Description

Translated fromJapanese

本発明は、ミリ波帯又はテラヘルツ波帯の無線通信に用いるMMIC(monolithic microwave integrated circuit:モノシリックマイクロ波集積回路)を実装したMMIC集積モジュールの技術に関する。  The present invention relates to a technology of an MMIC integrated module on which an MMIC (monolithic microwave integrated circuit) used for millimeter wave band or terahertz wave wireless communication is mounted.

旧来より、ミリ波又はテラヘルツ波の高周波RF(radio frequency)信号を扱うICパッケージが開発されている。このICパッケージは電磁波を入力するための導波管ポートを備えた金属体であり、金属表面には酸化防止の金メッキが形成されている。また、導波管フランジも形成されており、アライメント用のピンや固定ボルト等を必要とするため、サイズが大きく高コストとなってしまう。  Traditionally, IC packages that handle high-frequency RF (radio frequency) signals of millimeter waves or terahertz waves have been developed. This IC package is a metal body provided with a waveguide port for inputting electromagnetic waves, and an anti-oxidation gold plating is formed on the metal surface. In addition, a waveguide flange is also formed, which requires alignment pins, fixing bolts, and the like, resulting in a large size and high cost.

そこで近年では、製造上の高コスト化を抑制するため、誘電性の基板を積層させ、その積層過程において各基板にビアを形成したり基板表面に金属線を配線したりすることにより、旧来よりも簡易にICパッケージを含むMMIC集積モジュールを生成する手法が提案されている(非特許文献1)。  Therefore, in recent years, in order to suppress high manufacturing costs, dielectric substrates are laminated, and vias are formed in each substrate in the lamination process, or metal wires are wired on the substrate surface, and so on. In addition, a method for easily generating an MMIC integrated module including an IC package has been proposed (Non-Patent Document 1).

この非特許文献1に記載されたFig.1を図7に示す。このMMIC集積モジュール100は、複数の誘電性基板1’を積層し、積層させた誘電性基板群の一部でキャビティ7を形成し、そのキャビティ7の上壁面の表面に平面型のアンテナ10を配置することにより、形成されている。  Fig. 1 described in this Non-PatentDocument 1. 1 is shown in FIG. In this MMIC integratedmodule 100, a plurality ofdielectric substrates 1 ′ are laminated, acavity 7 is formed by a part of the laminated dielectric substrate group, and aplanar antenna 10 is formed on the surface of the upper wall surface of thecavity 7. It is formed by arranging.

また、誘電性基板1’の表面には、MMIC集積モジュール100の外部からキャビティ7内のアンテナ10へ信号を伝達するためのアンテナフィード線21やアンテナグランド線22が配設され、RFIC23に低周波信号を供給するための信号線24やRFIC23用のグランド線25も更に配設されている。RFIC23は、誘電性基板群の外部裏表面に配置され、信号線24を介して低周波信号を受信し、その低周波信号を用いて高周波RF信号を生成して、アンテナフィード線21を介してアンテナ10から出力する。  On the surface of thedielectric substrate 1 ′, anantenna feed line 21 and an antenna ground line 22 for transmitting a signal from the outside of the MMIC integratedmodule 100 to theantenna 10 in thecavity 7 are disposed, and theRFIC 23 has a low frequency. Asignal line 24 for supplying signals and aground line 25 for the RFIC 23 are further provided. The RFIC 23 is disposed on the outer back surface of the dielectric substrate group, receives a low frequency signal via thesignal line 24, generates a high frequency RF signal using the low frequency signal, and passes theantenna feed line 21. Output from theantenna 10.

このようなMMIC集積モジュール100において、RFIC23は、ワイヤボンディング又はフリップチップボンディングにより誘電性基板群の外部裏表面にマウント実装されている。かかる構成より、RFIC23からの高周波RF信号は図示しないボンディングやワイヤを介してアンテナ10に到達するため、高周波RF信号の信号損失が大きくなってしまう。その結果、高周波RF信号の送信側と受信側のそれぞれにおいて、信号パワーやノイズフィギュア等の特性劣化が生じることになる。  In such an MMIC integratedmodule 100, theRFIC 23 is mounted on the outer back surface of the dielectric substrate group by wire bonding or flip chip bonding. With this configuration, the high-frequency RF signal from theRFIC 23 reaches theantenna 10 through bonding or wires (not shown), so that the signal loss of the high-frequency RF signal increases. As a result, characteristics such as signal power and noise figure are deteriorated on the transmission side and reception side of the high-frequency RF signal.

そのため、RFICの上にアンテナを一体的に形成する手法も提案されている。図8は、2つ目の従来のMMIC集積モジュール100の構成を示す図である。このMMIC集積モジュールは、金属筐体31の内部に形成されたキャビティ7の底面にシリコン基板32を埋め込み、そのシリコン基板32のキャビティ7側の表面にRFICを有するMMICチップ2と回路の実装基板33を配置し、そのMMICチップ2の表面にアンテナ10を形成している。また、シリコン基板32の他方の表面に半球状のシリコンレンズ3’’をダイボンディング接合し、そのシリコンレンズ3’’の球部の一部を金属筐体31から外部へ突出するように配置している。  Therefore, a method of integrally forming an antenna on the RFIC has been proposed. FIG. 8 is a diagram showing a configuration of a second conventional MMIC integratedmodule 100. In this MMIC integrated module, asilicon substrate 32 is embedded in the bottom surface of acavity 7 formed inside ametal housing 31, and theMMIC chip 2 having an RFIC on the surface of thesilicon substrate 32 on thecavity 7 side and acircuit mounting substrate 33. And theantenna 10 is formed on the surface of theMMIC chip 2. Ahemispherical silicon lens 3 ″ is die-bonded to the other surface of thesilicon substrate 32, and a part of the spherical portion of thesilicon lens 3 ″ is disposed so as to protrude from themetal housing 31 to the outside. ing.

かかる構成より、MMICチップ2の上にアンテナ10が形成されているため、高周波RF信号の信号損失を抑制することができる。また、MMICチップ2に対して、そのMMICチップ2の化合物半導体材料と誘電率が近いシリコンからなるシリコン基板32とシリコンレンズ3’’を接合しているため、アンテナ10からの電波を効率良く空気中に放射することができる。  With this configuration, since theantenna 10 is formed on theMMIC chip 2, signal loss of the high-frequency RF signal can be suppressed. Further, since thesilicon substrate 32 made of silicon having a dielectric constant close to that of the compound semiconductor material of theMMIC chip 2 and thesilicon lens 3 ″ are bonded to theMMIC chip 2, the radio wave from theantenna 10 is efficiently air-aired. Can radiate in.

特に高抵抗シリコンは、テラヘルツ帯の領域において誘電体損失が無く、レンズやプリズムの材料として一般的に用いられている。また、シリコンレンズ3’’の半径やシリコン基板32の厚さを適切に設計することにより、ガウシアン性の良い放射パターンや高利得特性を得ることができる(特許文献1)。  In particular, high-resistance silicon has no dielectric loss in the terahertz band region and is generally used as a material for lenses and prisms. Further, by appropriately designing the radius of thesilicon lens 3 ″ and the thickness of thesilicon substrate 32, a radiation pattern with good Gaussian properties and high gain characteristics can be obtained (Patent Document 1).

なお、このMMIC集積モジュール100は、外部からの信号を受信可能である。アンテナ10で受信した信号は、ワイヤ34で接続された実装基板33を経由して信号端子35へ出力され、データ信号線36を通じて外部へ出力される。  The MMIC integratedmodule 100 can receive an external signal. A signal received by theantenna 10 is output to thesignal terminal 35 via themounting substrate 33 connected by thewire 34 and output to the outside through thedata signal line 36.

しかしながら、図8に示したMMIC集積モジュールでは、MMIC上のアンテナからの電波がシリコンレンズ側と金属筐体のキャビティ側の両方に放射するため、キャビティ側に放射された電磁波は損失となってしまい、アンテナ効率や利得が低下し、更にはMMICチップ上の電気線路に再結合することにより増幅器等の回路で発振現象が発生するという課題があった。  However, in the MMIC integrated module shown in FIG. 8, since the radio wave from the antenna on the MMIC radiates to both the silicon lens side and the cavity side of the metal housing, the electromagnetic wave radiated to the cavity side is lost.

[First Embodiment]
FIG. 1 is a cross-sectional view of an MMIC integratedmodule 100 according to the first embodiment. FIG. 2 is a perspective view of the MMIC integratedmodule 100. The MMIC integratedmodule 100 is mainly configured by including a multilayerdielectric substrate package 1, an MMICchip 2, and alens 3.

多層型誘電性基板パッケージ1は、セラミックやLTCC(Low Temperature Co-fired Ceramics)等の誘電性基板を積層することにより形成される。任意の誘電性基板には、その表面において、多層型誘電性基板パッケージ1の外表面に形成・配置された外部電極4に接続される配線5が形成され、更に誘電性基板間を導通するビア6が形成される。また、最上及び中間に位置する複数の誘電性基板を用いて凹形状の内部空間(キャビティ)7が形成され、そのキャビティ7の底面の上に、配線5及びビア6を介して外部電極4に電気的に接続される内部電極8が形成・配置される。  The multilayerdielectric substrate package 1 is formed by laminating dielectric substrates such as ceramics or LTCC (Low Temperature Co-fired Ceramics). Awiring 5 connected to theexternal electrode 4 formed and arranged on the outer surface of the multilayerdielectric substrate package 1 is formed on the surface of an arbitrary dielectric substrate, and further, a via that conducts between the dielectric substrates. 6 is formed. In addition, a concave internal space (cavity) 7 is formed using a plurality of dielectric substrates positioned at the uppermost and middle positions, and theexternal electrode 4 is formed on the bottom surface of thecavity 7 via thewiring 5 and thevia 6. An electrically connectedinternal electrode 8 is formed and arranged.

MMICチップ2は、多層型誘電性基板パッケージ1のキャビティ7に収まるサイズで形成され、そのキャビティ7の底面の上にフリップチップ実装される。例えば、金属性の接合用ボール9を用いて、キャビティ7内の内部電極8に電気的に接続する。MMICチップ2の表面には、図示しないRFIC(Radio Frequency Integrated Circuit)が形成され、更にオンチップ型のアンテナ10が形成されている。また、そのアンテナ10の形成面がキャビティ7の底面に向かい合うようにフリップチップ実装される。かかる構造により、外部電極4からの低周波信号を配線5,ビア6,内部電極8,接合用ボール9を介して受信し、その低周波信号を用いてRFICで高周波RF信号を生成し、その高周波RF信号の電波をアンテナ10から放射する。図1の場合、アンテナ10から上側と下側へ放射される。また、外部からの高周波RF信号をアンテナ10で受信し、同様の経路を逆に辿り外部電極4へ出力することも可能である。  TheMMIC chip 2 is formed in a size that can fit in thecavity 7 of the multilayerdielectric substrate package 1, and is flip-chip mounted on the bottom surface of thecavity 7. For example, ametallic bonding ball 9 is used to electrically connect to theinternal electrode 8 in thecavity 7. An RFIC (Radio Frequency Integrated Circuit) (not shown) is formed on the surface of theMMIC chip 2, and an on-chip type antenna 10 is further formed. Theantenna 10 is flip-chip mounted so that the surface on which theantenna 10 is formed faces the bottom surface of thecavity 7. With this structure, a low frequency signal from theexternal electrode 4 is received via thewiring 5, the via 6, theinternal electrode 8, and thebonding ball 9, and a high frequency RF signal is generated by the RFIC using the low frequency signal. A radio wave of a high frequency RF signal is radiated from theantenna 10. In the case of FIG. 1, it radiates | emits from theantenna 10 to the upper side and the lower side. It is also possible to receive a high-frequency RF signal from the outside by theantenna 10 and output it to theexternal electrode 4 by following the same path in reverse.

レンズ3は、半球状の形を有し、電磁波の波長の数倍以上ある径を有する。例えば、シリコン,テフロン,ポリエチレン、石英等の誘電性レンズを用いて形成される。接着剤11やUV樹脂等を用いてキャビティ7の開口面に配置され、固定される。その際、電磁波の放射パターンの中心軸がレンズ3の中心軸と一致するように配置することが好ましい。また、光学的に透明な材料をレンズ材料に用いることが好ましい。これにより、目視により、MMICチップ2やアンテナ10の位置との位置合わせが可能となり、実装も容易となる。また、シリコンを用いる場合には、例えば10kΩ・cm以上の高抵抗シリコンを用いることが好ましい。これにより、ガウシアン性の良い放射パターンや高利得特性を得ることができる。また、レンズ3の周縁を支える誘電性基板を変更したり、接合用ボール9のサイズを調整したりすることにより、そのキャビティ7に収容されるMMICチップ2に直接接合させることが好ましい。  Thelens 3 has a hemispherical shape and a diameter that is several times the wavelength of the electromagnetic wave. For example, a dielectric lens such as silicon, Teflon, polyethylene, or quartz is used. It arrange | positions and fixes to the opening surface of thecavity 7 using theadhesive agent 11 or UV resin. At this time, it is preferable to arrange the electromagnetic radiation pattern so that the central axis of the radiation pattern coincides with the central axis of thelens 3. Further, it is preferable to use an optically transparent material for the lens material. As a result, it is possible to align with the positions of theMMIC chip 2 and theantenna 10 by visual observation, and mounting becomes easy. Further, when silicon is used, it is preferable to use high resistance silicon of, for example, 10 kΩ · cm or more. As a result, it is possible to obtain a radiation pattern with good Gaussian properties and high gain characteristics. Further, it is preferable to directly join theMMIC chip 2 accommodated in thecavity 7 by changing the dielectric substrate that supports the periphery of thelens 3 or adjusting the size of the joiningball 9.

このような構成要素を備えたMMIC集積モジュール100において、本実施の形態では、アンテナ10と対向する誘電性基板の表面(キャビティ7の底面)に金属性の反射板12を形成する。例えば、キャビティ7の底面に位置する誘電性基板の一部を切除等することにより、アンテナ10の存在する位置において深さd×幅wの小キャビティ7’を形成し、その小キャビティ7’の底面の上を金属層で覆うようにする。  In the MMICintegrated module 100 including such components, in the present embodiment, ametallic reflector 12 is formed on the surface of the dielectric substrate (the bottom surface of the cavity 7) facing theantenna 10. For example, a part of the dielectric substrate located on the bottom surface of thecavity 7 is cut away to form asmall cavity 7 ′ having a depth d × width w at the position where theantenna 10 exists, and thesmall cavity 7 ′ Cover the bottom with a metal layer.

このように、小キャビティ7’の底面に金属層を形成することにより、アンテナ10から小キャビティ7’側へ放射された電波を反対方向へ反射させことができる。なお、小キャビティ7’の深さdとは、MMICチップ2のアンテナ形成面と小キャビティ7’の底面との間の距離であり、例えば、使用する帯域の中心波長λの1/6〜1/3の範囲内が好ましい。また、形成された金属層を接地するようにしても構わない。これにより、電波の反射効率を高めることができる。  Thus, by forming a metal layer on the bottom surface of thesmall cavity 7 ′, the radio wave radiated from theantenna 10 toward thesmall cavity 7 ′ can be reflected in the opposite direction. The depth d of thesmall cavity 7 ′ is a distance between the antenna formation surface of theMMIC chip 2 and the bottom surface of thesmall cavity 7 ′, and is, for example, 1/6 to 1 of the center wavelength λ of the band to be used. Within the range of / 3 is preferable. Further, the formed metal layer may be grounded. Thereby, the reflection efficiency of a radio wave can be improved.

また、本実施の形態では、反射板12を複数のビア6で囲むように形成・配置し、更にアンテナ10を複数の接合用ボール9で囲むように形成・配置する。例えば、接合用ボール9を小キャビティ7’の側壁面の一部として用いるようにする。図1のX−X’断面の一部を下から上に見た図を図3に示す。図3では、MMICチップ2上のアンテナ10と接合用ボール9との配置状態を示している。MMICチップ2のアンテナ形成面には、アンテナ10を囲むように金属層13が形成され、この金属層13の上に所定の間隔で接合用ボール9を配置する。更に、図1に示したように、図3のように配置された複数の接合用ボール9と同じ配置状態となるように複数のビア6を形成し、反射板12を囲むようにする。  In this embodiment, thereflector 12 is formed and arranged so as to be surrounded by the plurality ofvias 6, and theantenna 10 is formed and arranged so as to be surrounded by the plurality ofbonding balls 9. For example, thebonding ball 9 is used as a part of the side wall surface of the small cavity 7 '. FIG. 3 shows a part of the X-X ′ cross section of FIG. 1 viewed from the bottom to the top. FIG. 3 shows an arrangement state of theantenna 10 and thebonding ball 9 on theMMIC chip 2. Ametal layer 13 is formed on the antenna formation surface of theMMIC chip 2 so as to surround theantenna 10, and thebonding balls 9 are arranged on themetal layer 13 at a predetermined interval. Further, as shown in FIG. 1, a plurality ofvias 6 are formed so as to be in the same arrangement state as the plurality ofbonding balls 9 arranged as shown in FIG.

このように、アンテナ10を囲むように複数の接合用ボール9を配置し、反射板12を囲むように複数のビア6を形成することにより、アンテナ10から小キャビティ7’側へ放射された電波が水平方向へ分散することを防止できる。なお、接合用ボール9の間隔やビア6の間隔は、使用する帯域の中心波長λの1/4以下が好ましい。また、金属層13を接地し、その金属層13上の接合用ボール9や当該接合用ボール8に電気的に接続されるビア6をRFICのアース用電極の一部として用いるようにしても構わない。  In this way, by arranging the plurality ofbonding balls 9 so as to surround theantenna 10 and forming the plurality ofvias 6 so as to surround the reflectingplate 12, the radio wave radiated from theantenna 10 to thesmall cavity 7 ′ side. Can be prevented from spreading in the horizontal direction. The interval between thebonding balls 9 and the interval between thevias 6 is preferably ¼ or less of the center wavelength λ of the band to be used. Alternatively, themetal layer 13 may be grounded, and thebonding ball 9 on themetal layer 13 and the via 6 electrically connected to thebonding ball 8 may be used as part of the RFIC ground electrode. Absent.

本実施の形態によれば、MMICチップ2上のアンテナ10と対向するように小キャビティ7’の底面に反射板12を形成し、その反射板12を囲むように複数のビア6を形成し、更にアンテナ10を囲むように複数の接合用ボール9を配置するので、アンテナ10から小キャビティ7’側へ放射された電波を反対方向のみに反射することが可能となり、MMIC集積モジュール100から電波を効率的に放射することができる。  According to the present embodiment, the reflectingplate 12 is formed on the bottom surface of thesmall cavity 7 ′ so as to face theantenna 10 on theMMIC chip 2, and the plurality ofvias 6 are formed so as to surround the reflectingplate 12, Further, since a plurality ofbonding balls 9 are disposed so as to surround theantenna 10, it is possible to reflect the radio wave radiated from theantenna 10 toward the small cavity 7 'only in the opposite direction, and the radio wave from the MMICintegrated module 100 can be reflected.

[Second Embodiment]
FIG. 4 is a diagram illustrating the MMICintegrated module 100 according to the second embodiment. FIG. 2A is a cross-sectional view of the MMICintegrated module 100. FIG. 6B is a view of the XX ′ cross section of FIG.

本MMIC集積モジュール100は、第1の実施の形態と同様に、図示しない導体層が表面に形成された誘電体層(第1の実施の形態における誘電性基板)1’を積層することにより多層型誘電性基板パッケージ1を形成する。また、ビア6を形成した誘電体層1’を積層することにより、MMICチップ2を格納する長方形のキャビティ7を形成する。  Similar to the first embodiment, the MMICintegrated module 100 has a multilayer structure in which a dielectric layer (dielectric substrate in the first embodiment) 1 ′ having a conductor layer (not shown) formed thereon is laminated. A molddielectric substrate package 1 is formed. Further, by laminating thedielectric layer 1 ′ in which the via 6 is formed, arectangular cavity 7 for storing theMMIC chip 2 is formed.

キャビティ7を構成する最上の誘電体層1’に形成されたビア6aのサイズは他のビア6bのサイズと異なり、最上及びその下の誘電体層1’による枠部をステップ状とし、レンズ3を実装する。なお、誘電体層1’の材料は、セラミックスやガラスフィラーを混入したセラミックス混合材料、ポリイミド等のポリマー材料でもよいが、誘電損失が小さい材料が好ましい。セラミックス材料を用いた場合には、誘電体層1’を積層した後に高温で焼成を行う。誘電体層1’の厚さは数〜数十ミクロンであり、シルクスクリーン印刷やメッキ処理により形成する。一方、導体層の材料は、金、銀、タングステン、銅などでもよい。  The size of the via 6a formed in the uppermost dielectric layer 1 'constituting thecavity 7 is different from the size of theother vias 6b, and the frame portion formed by the uppermost and lower dielectric layer 1' is stepped to form thelens 3 Is implemented. The material of thedielectric layer 1 ′ may be a ceramic mixed material mixed with ceramics or glass filler, or a polymer material such as polyimide, but a material having a small dielectric loss is preferable. When a ceramic material is used, thedielectric layer 1 ′ is laminated and then fired at a high temperature. The dielectric layer 1 'has a thickness of several to several tens of microns and is formed by silk screen printing or plating. On the other hand, the material of the conductor layer may be gold, silver, tungsten, copper or the like.

本実施の形態では、第1の実施の形態と異なり、バンプ9’を用いてMMICチップ2をキャビティ7の底面にフリップチップ実装する。また、小キャビティ7’を形成することなく、反射板12をバンプ9’の実装面と同一平面に形成する。アンテナ10から反射板12までの距離は、第1の実施の形態と同様に、例えば、使用する帯域の中心波長λの1/6〜1/3の範囲内とする。  In the present embodiment, unlike the first embodiment, theMMIC chip 2 is flip-chip mounted on the bottom surface of thecavity 7 usingbumps 9 ′. Further, thereflector 12 is formed on the same plane as the mounting surface of the bump 9 'without forming the small cavity 7'. The distance from theantenna 10 to thereflector 12 is, for example, in the range of 1/6 to 1/3 of the center wavelength λ of the band to be used, as in the first embodiment.

本実施の形態によれば、MMICチップ2のアンテナ10と対向するように、キャビティ7の底面に反射板12を形成し、そのアンテナ10を囲むように複数のバンプ9’を配置するので、アンテナ10から小キャビティ7’側へ放射された電波を反対方向のみに反射することが可能となり、MMIC集積モジュール100から電波を効率的に放射することができる。  According to the present embodiment, thereflector 12 is formed on the bottom surface of thecavity 7 so as to face theantenna 10 of theMMIC chip 2, and the plurality ofbumps 9 ′ are arranged so as to surround theantenna 10. The radio waves radiated from 10 to thesmall cavity 7 ′ side can be reflected only in the opposite direction, and the radio waves can be efficiently radiated from the MMICintegrated module 100.

〔第3の実施の形態〕
図5は、第3の実施の形態に係るMMIC集積モジュール100を示す図である。同図(a)は、MMIC集積モジュール100の断面図である。同図(b)は、同図(a)のX−X’断面の一部を上から下に見た図である。以下、第1,2の実施の形態との相違点を中心に説明する。
[Third Embodiment]
FIG. 5 is a diagram showing an MMICintegrated module 100 according to the third embodiment. FIG. 2A is a cross-sectional view of the MMICintegrated module 100. FIG. 4B is a view of a part of the XX ′ cross section of FIG. Hereinafter, the difference from the first and second embodiments will be mainly described.

本実施の形態では、第1,2の実施の形態と異なり、反射板12をバンプ9’の実装面(誘電体層1a’)の下の誘電体層1b’の表面に形成し、その反射板12の上に位置する誘電体層1a’に複数の空孔14を形成し、その空孔14を囲むように複数のビア6を形成する。また、その複数のビア6の形成位置に沿うように誘電体層1a’の表面に金属層15を凹状に形成し、その金属層15の上にMMICチップ2をフリップチップ実装する。図5(b)では、金属層15の形成パターン、空孔14の配置パターン、ビア6の配置パターンの各例を示している。  In the present embodiment, unlike the first and second embodiments, the reflectingplate 12 is formed on the surface of thedielectric layer 1b ′ below the mounting surface (dielectric layer 1a ′) of thebump 9 ′, and the reflection thereof. A plurality ofholes 14 are formed in the dielectric layer 1 a ′ located on theplate 12, and a plurality ofvias 6 are formed so as to surround theholes 14. Further, ametal layer 15 is formed in a concave shape on the surface of the dielectric layer 1 a ′ so as to follow the formation positions of the plurality ofvias 6, and theMMIC chip 2 is flip-chip mounted on themetal layer 15. FIG. 5B shows examples of the formation pattern of themetal layer 15, the arrangement pattern of theholes 14, and the arrangement pattern of thevias 6.

第1の実施の形態では、誘電性基板の一部を排除することにより、小キャビティ7’の深さを制御している。しかし、これによりMMIC集積モジュール100の底面の厚さが薄くなるため、物理的強度が弱くなり、誘電性基板の反りが大きくなる可能性がある。これに対し、本実施の形態では、削除対象であった誘電性基板1a’の該当部分に空孔14を形成しているので、MMIC集積モジュール1の物理的な強度が高くなり、等価的に誘電率を制御してキャビティの深さを実質的に制御することができる。  In the first embodiment, the depth of the small cavity 7 'is controlled by eliminating a part of the dielectric substrate. However, the thickness of the bottom surface of the MMICintegrated module 100 is thereby reduced, so that the physical strength is weakened and the warping of the dielectric substrate may be increased. On the other hand, in the present embodiment, since theholes 14 are formed in the corresponding portions of the dielectric substrate 1a ′ to be deleted, the physical strength of the MMIC integratedmodule 1 is increased and equivalently The dielectric constant can be controlled to substantially control the cavity depth.

〔第4の実施の形態〕
図6は、第4の実施の形態に係るMMIC集積モジュール100の断面図である。本実施の形態では、レンズ3の材料として、特に、テフロン,ポリエチレン,石英等の低誘電率の誘電体を使用し、レンズ3の下面に凸レンズ3’を形成している。これにより、アンテナ10から放射される電波の放射パターンを適切に制御することができ、アンテナ利得を向上することができる。
[Fourth Embodiment]
FIG. 6 is a cross-sectional view of the MMICintegrated module 100 according to the fourth embodiment. In the present embodiment, a low dielectric constant dielectric material such as Teflon, polyethylene, or quartz is used as the material of thelens 3, and theconvex lens 3 ′ is formed on the lower surface of thelens 3. Thereby, the radiation pattern of the radio wave radiated from theantenna 10 can be appropriately controlled, and the antenna gain can be improved.

以上より、第1〜第4の実施の形態によれば、MMICチップ2上のアンテナ10と対向するようにキャビティ7又は小キャビティ7’の底面に反射板12を形成・配置したので、アンテナ10から電波を効率的に放射でき、電波の損失を低減でき、結果としてアンテナ効率と利得を改善することができる。また、アンテナ10を囲むように接合用ボール9又はバンプ9’を配置し、反射板12を囲むようにビア6を形成したので、大気中への放射を抑制し、MMICチップ上に形成された増幅器等の発振を防止することができる。  As described above, according to the first to fourth embodiments, the reflectingplate 12 is formed and arranged on the bottom surface of thecavity 7 or thesmall cavity 7 ′ so as to face theantenna 10 on theMMIC chip 2. Can efficiently radiate radio waves, reduce radio wave loss, and as a result, improve antenna efficiency and gain. Further, since thebonding balls 9 or thebumps 9 ′ are arranged so as to surround theantenna 10 and the via 6 is formed so as to surround thereflector 12, the radiation to the atmosphere is suppressed and the via is formed on the MMIC chip. Oscillation of an amplifier or the like can be prevented.
