Description

Translated fromJapanese

本発明は、複数の蒸着源を備えた蒸着装置に関する。 The present invention relates to a vapor deposition apparatus equipped with a plurality of vapor deposition sources.

近年、有機発光素子は、低電圧駆動による高輝度発光が可能な発光素子として注目されている。このような発光素子を構成する有機材料には、高分子と低分子がある。低分子材料を用いた発光素子は、通常、真空蒸着法により形成する。有機発光素子は複数の機能層からできており、機能層としては、ホール注入層、ホール輸送層、発光層、電子輸送層、電子注入層などがあり、これらが陽極と陰極の間に順次蒸着により形成される。
一般的に用いられる蒸着装置には、インライン型とクラスター型がある。インライン型は、大判基板の成膜に適しており、一方でクラスター型は、小型から大型基板まで、用途に合わせた対応が可能である。また、発光素子の層構成変更に対しても、蒸着室の追加が容易であり、柔軟に対応が可能である。クラスター型の蒸着装置においては、クロスコンタミネーション、タクト等を考慮した場合、各層ごとにチャンバーを設けることが基本的には望ましい。しかしながら、装置コストを抑え、且つ装置の小型化のために蒸着室の数を減らしたり、或いは複数の材料を同時蒸着したりするために、同一チャンバー内で異なる複数の材料を蒸着する場合がある。
特許文献1には、複数の蒸着源を備えたクラスター型の蒸着装置が開示されており、係る蒸着装置においては、個々の蒸着源にシャッターが配置され、該シャッターの開閉により、蒸着・非蒸着を制御している。
In recent years, organic light-emitting devices have attracted attention as light-emitting devices that can emit high-intensity light by driving at low voltages. Organic materials constituting such light-emitting elements include polymers and low molecules. Light-emitting elements using low-molecular materials are usually formed by vacuum evaporation. Organic light-emitting devices are made of multiple functional layers, and the functional layers include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer, which are successively deposited between an anode and a cathode. formed by
There are two types of commonly used vapor deposition equipment: in-line type and cluster type. The in-line type is suitable for forming films on large-sized substrates, while the cluster type can be used to suit the application, from small to large substrates. Further, it is easy to add a deposition chamber to change the layer structure of a light emitting element, and this can be flexibly handled. In a cluster-type vapor deposition apparatus, it is basically desirable to provide a chamber for each layer in consideration of cross-contamination, tact, etc. However, in order to reduce equipment costs and reduce the number of deposition chambers to make the equipment more compact, or to deposit multiple materials simultaneously, there are cases in which multiple different materials are deposited within the same chamber. .
Patent Document 1 discloses a cluster-type vapor deposition apparatus equipped with a plurality of vapor deposition sources, and in such a vapor deposition apparatus, a shutter is arranged at each vapor deposition source, and by opening and closing the shutter, it is possible to switch between vapor deposition and non-evaporation. is under control.

特開2015-124440号公報Japanese Patent Application Publication No. 2015-124440

特許文献1に開示されているように、複数の蒸着源を有するインライン型の蒸着装置においては、蒸着源の選択をシャッターの開閉で制御している。
一方、一つの蒸着室内で複数層を順次形成する場合には、タクト短縮のため、各蒸着源の蒸着レートが変動しないよう常にモニターで蒸着レートを測定し、制御しておくことが望ましい。しかしながら、シャッターが蒸着源に近い場合、シャッターが閉じている状態では、シャッターが邪魔をして蒸着レートを膜厚センサーでモニターすることができない。従って、シャッターが閉じている時でも蒸着レートをモニターするためには、シャッターを蒸着源からある程度離す必要がある。そして、シャッターを蒸着源から離した状態で、シャッターが閉じている時に被蒸着基板に蒸着源からの蒸発物の付着を防止するためには、シャッターのサイズを大きくする必要がある。
シャッターのサイズを大きくすると、複数のシャッターを同時に開いた場合にシャッター同士が干渉しないように、隣り合う蒸着源の間隔を広げる必要があり、蒸着室のサイズの大型化を招くという問題があった。
本発明の課題は、複数の蒸着源と、個々の蒸着源に対応するシャッターと、を有するクラスター型の蒸着装置において、装置の大型化を招くことなく、常時蒸着レートをモニターすることができる構成を提供することにある。
As disclosed inPatent Document 1, in an in-line vapor deposition apparatus having a plurality of vapor deposition sources, selection of the vapor deposition sources is controlled by opening and closing a shutter.
On the other hand, when a plurality of layers are sequentially formed in one deposition chamber, it is desirable to constantly measure and control the deposition rate with a monitor so that the deposition rate of each deposition source does not fluctuate in order to shorten the takt time. However, when the shutter is close to the deposition source, the deposition rate cannot be monitored with the film thickness sensor because the shutter interferes with the closed state. Therefore, in order to monitor the deposition rate even when the shutter is closed, it is necessary to keep the shutter some distance from the deposition source. In order to prevent evaporated matter from the deposition source from adhering to the substrate to be deposited when the shutter is closed and the shutter is separated from the deposition source, it is necessary to increase the size of the shutter.
When increasing the size of the shutter, it was necessary to increase the distance between adjacent deposition sources to prevent interference between shutters when multiple shutters were opened at the same time, which caused the problem of increasing the size of the deposition chamber. .
An object of the present invention is to configure a cluster-type evaporation apparatus that has a plurality of evaporation sources and shutters corresponding to each evaporation source so that the evaporation rate can be constantly monitored without increasing the size of the apparatus. Our goal is to provide the following.

本発明は、水平方向に並んで配置した第一の蒸着源と第二の蒸着源と、前記第一の蒸着源の開口部の上方に配置された第一のシャッターと、前記第二の蒸着源の開口部の上方に配置された第二のシャッターと、蒸着室内に有する蒸着装置であって、
前記第一のシャッターと前記第二のシャッターとは互いに高さが異なり、且つ、それぞれ独立に水平方向に移動することにより開閉し、垂直方向からの平面視において前記第一のシャッターと前記第二のシャッターとが共に開状態で互いに重なる領域を有し、
前記重なる領域において、前記第一のシャッターと前記第二のシャッターの間を隔てる隔壁を有し、前記隔壁は前記蒸着室に固定されていることを特徴とする。
The present invention includesa first vapor deposition sourceand a second vapor deposition source arranged side by side in the horizontal direction,a first shutter arranged above anopening of thefirst vapor deposition source, anda second vapor deposition source. A vapor deposition apparatushaving a second shutter disposed above an opening of a vapor deposition sourcein a vapor deposition chamber ,
The first shutterand the second shutter have different heights, and are opened and closed by movingindependently in the horizontal direction, andthe first shutter and the second shutter are different in height from each other when viewed from the vertical direction. have a regionwhere the shutters overlap each other in the open state,
In the overlapping region, a partition wall is provided to separatethe first shutterand the second shutter, and the partition wall is fixed to the vapor deposition chamber .

本発明によれば、二つのシャッターを互いに異なる高さに設けることで、両シャッターが開いた状態でも互いに干渉することがない。よって、シャッターを蒸着源から離し、且つシャッター自体を大型化しても、二つの蒸着源同士の間隔を広げる必要がなく、装置を大型化するおそれがない。また、二つのシャッターの間に隔壁を設けたことにより、シャッターの高さを異ならせたことによるクロスコンタミネーションなどの不都合も抑制される。 According to the present invention, by providing the two shutters at different heights, they do not interfere with each other even when both shutters are open. Therefore, even if the shutter is separated from the vapor deposition source and the shutter itself is increased in size, there is no need to widen the distance between the two vapor deposition sources, and there is no risk of increasing the size of the apparatus. Further, by providing a partition wall between the two shutters, inconveniences such as cross contamination caused by different heights of the shutters can be suppressed.

本発明の蒸着装置は、複数の蒸着源と、個々の蒸着源に対応するシャッターと、を有するクラスター型の蒸着装置である。本発明においては、2個の蒸着源に対応する二つのシャッターの高さを互いに異なるように構成し、さらに、これらシャッターの重なる領域において、二つのシャッター間に隔壁を設けたことに特徴を有する。 The vapor deposition apparatus of the present invention is a cluster type vapor deposition apparatus having a plurality of vapor deposition sources and a shutter corresponding to each vapor deposition source. The present invention is characterized in that the heights of the two shutters corresponding to the two evaporation sources are configured to be different from each other, and a partition wall is provided between the two shutters in the area where these shutters overlap. .

先ず、複数の蒸着源と、シャッターとを有する従来の蒸着装置について図4を用いて説明する。図4は、従来のクラスター型の蒸着装置の蒸着室100の構成を模式的に示す断面図であり、主要な構成部材のみを図示している。図中、1,2は蒸着源であり、水平方向に所定の距離を置いて配置され、それぞれ上方に開口を有する坩堝1a,2aを有している。坩堝1a,2aの外周にはヒーター1b,2bが配置され、該ヒーター1b,2bによって坩堝1a,2aを加熱することにより、坩堝1a,2a内に収納された蒸着材料1c,2cを蒸発させて上方に向けて飛散させることができる。尚、蒸着源1,2は、図示した部材以外にも、不図示のリフレクターや熱電対などの部材を有している。 First, a conventional vapor deposition apparatus having a plurality of vapor deposition sources and a shutter will be described with reference to FIG. FIG. 4 is a cross-sectional view schematically showing the configuration of avapor deposition chamber 100 of a conventional cluster-type vapor deposition apparatus, and only main constituent members are shown. In the figure, 1 and 2 are vapor deposition sources, which are arranged at a predetermined distance in the horizontal direction and havecrucibles 1a and 2a each having an opening at the top.Heaters 1b and 2b are arranged around the outer periphery of thecrucibles 1a and 2a, and by heating thecrucibles 1a and 2a with theheaters 1b and 2b, thevapor deposition materials 1c and 2c stored in thecrucibles 1a and 2a are evaporated. It can be scattered upwards. Incidentally, thevapor deposition sources 1 and 2 include members such as reflectors and thermocouples (not shown) in addition to the members shown.

蒸着室100の天井には基板ホルダー20が回転軸20aによって回転可能に取り付けられ、該基板ホルダー20の下面に被蒸着基板9が取り付けられ、さらに、被蒸着面(下面)側にマスク10が取り付けられている。蒸着時には、被蒸着基板9は被蒸着面内で回転し、マスク10の開口部に蒸着源1,2からの蒸発物が蒸着する。 Asubstrate holder 20 is rotatably attached to the ceiling of thevapor deposition chamber 100 by a rotatingshaft 20a, a substrate 9 to be vaporized is attached to the lower surface of thesubstrate holder 20, and amask 10 is attached to the surface to be vaporized (lower surface). It is being During vapor deposition, the substrate 9 to be vapor-deposited rotates within the surface to be vapor-deposited, and the evaporated material from the vapor-deposition sources 1 and 2 is vapor-deposited into the opening of themask 10.

蒸着源1,2に対しては、それぞれからの蒸発物の被蒸着基板9への蒸着を妨げるシャッター5,6が配置されている。シャッター5,6はそれぞれ、支持材5a,6aによって回転し、図4に実線で示される位置は開状態、破線5b,6bで示される位置は閉状態である。シャッター5,6は、閉状態5b、6bでは、それぞれ、蒸着源1,2の開口部と被蒸着基板9との間を遮って、被蒸着基板9への蒸発物の飛散を妨げる。よって、図4に示される蒸着装置においては、シャッター5,6の開閉によって、被蒸着基板9への蒸着を制御することができる。例えば、蒸着材料1c,2cの一方のみを蒸着する場合には、係る一方の側のシャッターを開状態とし、他方のシャッターを閉状態とする。また、シャッター5,6を両方開状態として蒸着を行えば、蒸着材料1c、2cの共蒸着を行うこともできる。Shutters 5 and 6 are arranged for theevaporation sources 1 and 2 to prevent evaporated substances from each from being evaporated onto the substrate 9 to be evaporated. Theshutters 5 and 6 are rotated by supportingmembers 5a and 6a, respectively, and the positions shown by solid lines in FIG. 4 are in the open state, and the positions shown bybroken lines 5b and 6b are in the closed state. In the closedstates 5b and 6b, theshutters 5 and 6 block the spaces between the openings of theevaporation sources 1 and 2 and the substrate 9 to be evaporated, and prevent the evaporated material from scattering to the substrate 9 to be evaporated. Therefore, in the vapor deposition apparatus shown in FIG. 4, vapor deposition on the substrate 9 to be vapor deposited can be controlled by opening and closing theshutters 5 and 6. For example, when depositing only one of thedeposition materials 1c and 2c, the shutter on one side is opened and the other shutter is closed. Further, if vapor deposition is performed with bothshutters 5 and 6 open, thevapor deposition materials 1c and 2c can be co-evaporated.

図4中、11は水平方向において蒸着源1,2を互いに仕切る仕切り板である。また、7,8はそれぞれ、蒸着源1,2の蒸着レートを測定するモニターである。ここで、閉状態の際にシャッター5,6が蒸着源1,2の開口部に近い場合、閉状態ではシャッター5,6に遮られてモニター7,8が蒸着源1,2の蒸着レートを測定することができない。シャッター5,6を蒸着源1,2の開口部から上方に離して配置すれば、モニター7,8はシャッター5,6と蒸着源1,2の開口部との隙間から蒸着レートを測定することができる。しかしながら、図4に一点鎖線で示すように、蒸着源1,2の開口部から被蒸着基板9に向かって、蒸発物の飛散領域が広がるため、シャッター5,6を蒸着源1,2から離すほど、シャッター5,6を大きくする必要がある。シャッター5,6は、開状態では互いに接近するため、シャッター5,6を大きくすれば、蒸着源1,2の間隙を広くする必要があり、蒸着室100を大型化する必要があった。 In FIG. 4, 11 is a partition plate that partitions thevapor deposition sources 1 and 2 from each other in the horizontal direction. Further, 7 and 8 are monitors that measure the evaporation rates of theevaporation sources 1 and 2, respectively. Here, if theshutters 5 and 6 are close to the openings of theevaporation sources 1 and 2 in the closed state, themonitors 7 and 8 are blocked by theshutters 5 and 6 and monitor the evaporation rates of theevaporation sources 1 and 2 in the closed state. cannot be measured. If theshutters 5 and 6 are placed apart from the openings of thedeposition sources 1 and 2 above, themonitors 7 and 8 can measure the deposition rate from the gap between theshutters 5 and 6 and the openings of thedeposition sources 1 and 2. I can do it. However, as shown by the dashed line in FIG. 4, the scattering area of the evaporated material expands from the openings of theevaporation sources 1 and 2 toward the substrate 9 to be evaporated, so theshutters 5 and 6 are moved away from theevaporation sources 1 and 2. The larger the distance, the larger theshutters 5 and 6 need to be. Since theshutters 5 and 6 approach each other in the open state, if theshutters 5 and 6 are made larger, it is necessary to widen the gap between thedeposition sources 1 and 2, and thedeposition chamber 100 needs to be enlarged.

本発明においては、第一の特徴として、シャッター5,6が閉状態の時もモニター7,8が蒸着レートを測定できるように、シャッター5,6を蒸着源1,2から上方に離して配置する。当然、シャッター5,6を大きくする必要があるが、ここで、図5に示すように、シャッター5,6の高さを互いに異ならせ、開状態で互いに重なるように配置することで、蒸着源1,2の間隔を広げる必要がなくなる。 The first feature of the present invention is that theshutters 5 and 6 are placed upwardly away from thedeposition sources 1 and 2 so that themonitors 7 and 8 can measure the deposition rate even when theshutters 5 and 6 are closed. do. Naturally, it is necessary to make theshutters 5 and 6 larger, but as shown in FIG. There is no need to widen the interval between 1 and 2.

しかしながら、シャッター5,6の高さを互いに異ならせた場合、蒸着源1,2間でクロスコンタミネーションを生じ易くなることがわかった。図6を用いて図5の蒸着装置におけるクロスコンタミネーションについて説明する。尚、図6は図5と同じ構成の蒸着装置の説明に必要な部材のみを図示する。 However, it has been found that when the heights of theshutters 5 and 6 are made different from each other, cross-contamination is likely to occur between thevapor deposition sources 1 and 2. Cross contamination in the vapor deposition apparatus of FIG. 5 will be explained using FIG. 6. Note that FIG. 6 shows only the members necessary for explaining the vapor deposition apparatus having the same configuration as FIG. 5.

シャッター5,6の裏面(蒸着源1,2側)には、閉状態の際に蒸着源1,2からの蒸発物が付着する。図6(a)に示すように、シャッター5,6を同時に開状態とした場合、高さが高い方のシャッター6の裏面に付着した蒸発物31が剥離して、高さが低い方のシャッター5の表面に落下する場合がある。この状態で、図6(b)に示すようにシャッター5を閉状態に向けて回転させると、シャッター5上の蒸発物31aが、図6(c)に示すように蒸着源1上に落下するおそれがある。蒸着源1上に落下した蒸発物31aは、蒸着源1の開口部を塞いだり、ヒーター1bによって加熱されて蒸着材料1cと共に飛散して被蒸着基板9に蒸着(クロスコンタミネーション)してしまうおそれがある。 Evaporated substances from thevapor deposition sources 1 and 2 adhere to the back surfaces of theshutters 5 and 6 (on thevapor deposition sources 1 and 2 side) when the shutters are in the closed state. As shown in FIG. 6(a), when theshutters 5 and 6 are opened at the same time, the evaporatedmatter 31 attached to the back surface of thehigher shutter 6 is peeled off and theshutter 6 is opened. It may fall on the surface of 5. In this state, when theshutter 5 is rotated toward the closed state as shown in FIG. 6(b), the evaporatedmatter 31a on theshutter 5 falls onto thedeposition source 1 as shown in FIG. 6(c). There is a risk. The evaporatedmaterial 31a that has fallen onto theevaporation source 1 may block the opening of theevaporation source 1, or be heated by theheater 1b and be scattered together with theevaporation material 1c, causing evaporation onto the substrate 9 to be evaporated (cross contamination). There is.

本発明においては、第二の特徴として、シャッター5,6間に隔壁を設けることで、図6に示したようなシャッター6の裏面に付着した蒸発物の蒸着源1への落下を防止する。図1を用いて説明する。 The second feature of the present invention is that by providing a partition between theshutters 5 and 6, evaporated matter adhering to the back surface of theshutter 6 as shown in FIG. 6 is prevented from falling to theevaporation source 1. This will be explained using FIG.

図1は、本発明の蒸着装置の好ましい実施形態の蒸着室の主要な構成を概略的に示す垂直方向の断面図である。本実施形態の構成は、基本的に図5に示した従来の蒸着装置と同様の構成を備え、さらに、隔壁12を備えている。 FIG. 1 is a vertical sectional view schematically showing the main structure of a vapor deposition chamber of a preferred embodiment of the vapor deposition apparatus of the present invention. The configuration of this embodiment is basically the same as the conventional vapor deposition apparatus shown in FIG. 5, and further includespartition walls 12.

本実施形態においては、図5の蒸着装置と同様に、二つの蒸着源1,2と、これらの蒸着源1,2の蒸着レートを測定する二つのモニター7,8を備えている。蒸着源1,2に対しては、蒸発物の被蒸着基板9への飛散を妨げるシャッター5,6が配置されている。シャッター5,6は、閉状態においてもモニター7,8が蒸着レートを測定し得るように、蒸着源1,2から上方に離れた位置において支持材5a,6aにより回転可能に配置されている。シャッター5,6は、垂直方向からの平面視において、開状態で互いに重なる領域を有しており、本実施形態においては、該重なる領域において、シャッター5,6間を遮る隔壁12が設けられている。 In this embodiment, like the vapor deposition apparatus of FIG. 5, twovapor deposition sources 1 and 2 and twomonitors 7 and 8 for measuring the vapor deposition rates of thesevapor deposition sources 1 and 2 are provided.Shutters 5 and 6 are arranged for theevaporation sources 1 and 2 to prevent evaporated materials from scattering onto the substrate 9 to be evaporated. Theshutters 5 and 6 are rotatably arranged by supportingmembers 5a and 6a at positions upwardly away from thevapor deposition sources 1 and 2 so that themonitors 7 and 8 can measure the vapor deposition rate even in the closed state. Theshutters 5 and 6 have regions that overlap each other in the open state when viewed in plan from the vertical direction, and in this embodiment, apartition wall 12 that blocks the space between theshutters 5 and 6 is provided in the overlap region. There is.

シャッター5,6と隔壁12、仕切り板11の垂直方向からの平面視を図3(a)に示す。図3(a)中、破線で示す5c,6cはそれぞれ、回転によってシャッター5,6の占める領域の外周である。よって、領域5cと6cとが重なる領域21(斜線のハッチングで示される領域)が、シャッター5,6が開状態で互いに重なる領域である。隔壁12は該領域21に重なるように、シャッター5,6の間の高さに配置されており、シャッター5,6がいずれも開状態の時、シャッター5,6間を隔てる。係る隔壁12により、シャッター6の裏面に付着した蒸発物が剥離して落下した場合でも、剥離した蒸発物は隔壁12上に落下し、シャッター5の表面には落下しない。よって、シャッター6の裏面に付着した蒸発物が蒸着源1に落下して蒸着源1の開口部を塞いだり、クロスコンタミネーションを生じるといった不都合が抑制される。 A vertical plan view of theshutters 5 and 6, thepartition wall 12, and thepartition plate 11 is shown in FIG. 3(a). In FIG. 3A, 5c and 6c indicated by broken lines are the outer peripheries of the regions occupied by theshutters 5 and 6 due to rotation, respectively. Therefore, the region 21 (indicated by diagonal hatching) where theregions 5c and 6c overlap is the region where theshutters 5 and 6 overlap each other in the open state. Thepartition wall 12 is placed at a height between theshutters 5 and 6 so as to overlap thearea 21, and separates theshutters 5 and 6 when both are in the open state. Due to thepartition wall 12, even if the evaporated matter adhering to the back surface of theshutter 6 is peeled off and falls, the separated evaporated material falls onto thepartition wall 12 and does not fall onto the surface of theshutter 5. Therefore, inconveniences such as evaporated matter adhering to the back surface of theshutter 6 falling into thevapor deposition source 1 and blocking the opening of thevapor deposition source 1 or causing cross contamination can be suppressed.

本実施形態においては、隔壁12は、長手方向(紙面上下方向)の両端において支持材22で支持されている。また、本実施形態では、蒸着源1,2間を遮る仕切り板11の上端に、蒸着源2に向かって第二の隔壁13が取り付けられている。これにより、シャッター5の裏面に付着した蒸発物が剥離して蒸着源2側に落下するのを抑制し、該蒸発物によって、蒸着源2の開口部が塞がれたり、クロスコンタミネーションが生じるのが抑制される。 In this embodiment, thepartition wall 12 is supported by supportingmembers 22 at both ends in the longitudinal direction (vertical direction in the drawing). Further, in this embodiment, asecond partition wall 13 is attached to the upper end of thepartition plate 11 that blocks the gap between thevapor deposition sources 1 and 2, facing toward thevapor deposition source 2. This suppresses the evaporated matter adhering to the back surface of theshutter 5 from peeling off and falling to thedeposition source 2 side, and the evaporated matter blocks the opening of theevaporation source 2 and causes cross contamination. is suppressed.

さらに、図2に本発明の蒸着装置の他の実施形態の蒸着室の主要な構成を概略的に示す垂直方向の断面図を示し、図3(b)に図2の蒸着装置を上方から見た平面概略図を示す。本実施形態では、図1の蒸着装置に加えて、隔壁(以下、第一の隔壁と記す)12と第二の隔壁13とをつなぐ第一の側壁14と、第一の隔壁12の蒸着源1側の端部より上方に向かって突出する第二の側壁15と、を有している。このように、側壁14,15を設けることで、シャッター5,6の裏面に付着した蒸発物が剥離して、それぞれ蒸着源2,1側に落下するのをより効果的に抑制することができる。また、本実施形態のように、仕切り板11、第二の隔壁13、第一の側壁14、第一の隔壁12、第二の側壁15が順次連結されているため、一体で取り扱うことができ、付着した蒸発物の除去など、メンテナンスが容易である。Furthermore, FIG. 2shows a vertical cross-sectional view schematically showing the main structure of the vapor deposition chamber of another embodiment of the vapor deposition apparatus of the present invention, and FIG. 3(b) shows the vapor deposition apparatus of FIG. 2 from above. A schematic plan view is shown . In this embodiment, in addition to the vapor deposition apparatus of FIG. It has asecond side wall 15 that projects upward from the first end. By providing theside walls 14 and 15 in this way, it is possible to more effectively prevent the evaporated matter adhering to the back surfaces of theshutters 5 and 6 from peeling off and falling toward thevapor deposition sources 2 and 1, respectively. . Furthermore, as in this embodiment, thepartition plate 11, thesecond partition wall 13, thefirst side wall 14, thefirst partition wall 12, and thesecond side wall 15 are connected in sequence, so they cannot be handled as one unit. Maintenance, such as removing attached evaporated matter, is easy.

図1、図2に示した実施形態では、蒸着源が2個の場合を示したが、蒸着源が3個以上の場合でも、そのうちの2個の蒸着源について、本発明を適用すればよい。また、蒸着源が4個の場合には、2個一組として、それぞれの組に本発明を適用すればよい。いずれの場合も、隣り合う組の蒸着源同士は仕切り板で仕切ることが好ましい。また、図1、図2には、被蒸着基板を回転させて蒸着を行う形態を示したが、被蒸着基板を固定して、蒸着源を回転テーブルに載せて回転させる形態であってもよい。また、シャッター5,6は回転させて開状態と閉状態とする構成を示したが、水平移動する形態であれば、移動形態は特に限定されない。 In the embodiment shown in FIGS. 1 and 2, the case where there are two evaporation sources is shown, but even if there are three or more evaporation sources, the present invention may be applied to two of them. . Furthermore, when there are four evaporation sources, the present invention may be applied to each set of two. In either case, it is preferable that adjacent sets of vapor deposition sources be separated from each other by a partition plate. Furthermore, although FIGS. 1 and 2 show a configuration in which the deposition target substrate is rotated to perform the deposition, it is also possible to use a configuration in which the deposition target substrate is fixed and the deposition source is placed on a rotating table and rotated. . Moreover, although theshutters 5 and 6 are rotated to open and close, the movement form is not particularly limited as long as theshutters 5 and 6 are moved horizontally.

図1、図5に示す構成で、4個の蒸着源を備えた蒸着装置において、蒸着源を2個一組として、異なる4種の蒸着材料を用いて共蒸着を行った。一方の組のシャッターは同時に開状態、他方の組のシャッターは同時に閉状態とする工程を、5分ずつ、開状態と閉状態とを入れ替えて繰り返し、各蒸着源の蒸着レートを1.0nm/sで一定とし、連続120時間行った。また、図2の蒸着装置において、蒸着レートを1.0nm/sで一定とし、2個のシャッターを同時に5分間隔で開状態と閉状態とを繰り返して連続120時間、異なる蒸着材料の共蒸着を行った。蒸着終了後、蒸着源の加熱を停止し、蒸着室を大気状態に戻した後、各蒸着源の周辺をワイパーでふき取り、ワイパーに付着した物質をHPLC(高速液体クロマトグラフ)分析にかけた。その結果、図1、図2の蒸着装置では、いずれの蒸着源においても、他の蒸着源からの蒸発物は観察されなかったが、図5の蒸着装置では、同じ組の一方の蒸着源に他方の蒸着源からの蒸発物の付着が認められた。 In a vapor deposition apparatus having the configuration shown in FIGS. 1 and 5 and equipped with four vapor deposition sources, co-evaporation was performed using four different vapor deposition materials using a set of two vapor deposition sources. The process of opening one set of shutters at the same time and closing the other set of shutters at the same time is repeated for 5 minutes, alternating between the open and closed states, and the evaporation rate of each evaporation source is set to 1.0 nm/ The test was carried out continuously for 120 hours at a constant temperature of 120 s. In addition, in the evaporation apparatus shown in Fig. 2, the evaporation rate was kept constant at 1.0 nm/s, and the two shutters were simultaneously opened and closed at 5-minute intervals to perform co-evaporation of different evaporation materials for 120 consecutive hours. I did it. After the vapor deposition was completed, the heating of the vapor deposition sources was stopped and the vapor deposition chamber was returned to atmospheric conditions. The area around each vapor deposition source was wiped with a wiper, and the substances adhering to the wipers were subjected to HPLC (high performance liquid chromatography) analysis. As a result, in the evaporation apparatus of FIGS. 1 and 2, no evaporated matter from other evaporation sources was observed in any of the evaporation sources, but in the evaporation apparatus of FIG. Adhesion of evaporated matter from the other evaporation source was observed.
