Generally, semiconductor devices are manufactured by forming a plurality of semiconductor device regions having desired functions on a single semiconductor substrate such as Si, GaAS, or GAP by performing treatments such as epitaxial growth and impurity diffusion. The elements are obtained by performing dicing or the like and mechanically dividing each element using dividing grooves, and these elements are assembled into products.

As a means of this division, as shown in FIG. 1, the semiconductor substrate 1 is pasted on a highly extensible sheet 3 coated with an adhesive 2, a dividing groove 4 is formed, and an external force is applied to the rear sheet. A widely used method is to obtain the element 5 by achieving this and at the same time prevent the scattering of minute elements after division. There are some problems. When the process of assembling such semiconductor elements into products becomes automated, it is required to supply each element in a fixed array, and this requires a certain degree of strength when pasting it onto a sheet and dividing it. It is necessary that the element be easily peeled off from the sheet, and conventional methods have not been able to fully meet this requirement. This invention has been made in view of this point, and the semiconductor substrate is divided into semiconductor elements while being attached to the first sheet, and the first sheet is divided into semiconductor elements.
After pasting the second sheet on the other top surface of the semiconductor substrate to which the sheet has not been pasted, the first sheet is peeled off and the second sheet is pasted.
The present invention provides a manufacturing method for obtaining semiconductor elements in a predetermined arrangement on a sheet.

That is, when a semiconductor substrate is attached to a first sheet, a thin resin film is formed on the main surface of the substrate facing the sheet and attached to the sheet, so that the first sheet can be easily peeled off after being divided into elements. , the elements are attached and arranged on the second sheet. Examples of the present invention will be described below.

A gap light emitting device will be described below as an example of a semiconductor device. As shown in FIG. 2, 11 is a gap substrate that has been subjected to epitaxial growth and impurity diffusion, and one main surface of this substrate 11 is coated with vinyl resin dissolved in a solvent, and then dried. A thin film 12 is produced. The substrate 11 is attached to the '1st sheet 13 with the main surface having the resin thin film facing the first sheet 13 coated with the acrylic adhesive 14. Next, as shown in FIG. 2, dividing grooves 16 are formed by dicing from the other main surface 15 of the substrate 11 to which no sheet is attached so that light emitting elements of a predetermined size can be obtained. When the sheet is stretched in the outer circumferential direction while applying pressure through the sheet, the substrate is cracked in a predetermined manner along the dividing grooves, and a predetermined Gap light emitting element 17 is obtained.
This state is shown in FIG. 2C. A Gap light emitting element 17 is obtained which is divided on the first sheet 13, and the resin thin film 12 is also divided in the same way and attached to one surface of the light emitting element 17. Then a second sheet 1 with adhesive 18 applied to the surface
9 to the other main surface 20 of the substrate to which the first sheet 13 is not attached (this main surface is attached to the first sheet of the element stuck on the stretched first sheet). After affixing the first sheet 13 with the adhesive-coated surfaces facing each other (the opposite main surface), the first sheet 13 is peeled off in the direction of the arrow, as shown in FIG. 20. At this time, the resin thin film 12 is separated from the elements while remaining attached to the adhesive of the first sheet, and the light emitting elements are attached and arranged on the second sheet.
When the light emitting elements in this state are assembled into a semiconductor light emitting device, the work can be done extremely efficiently since all the elements are arranged with the same main surface facing up and at appropriate intervals on the sheet. I can recommend it. As described above, according to the method of the present invention, the resin thin film is interposed between the sheet and the substrate to attach the substrate, so that the thin film is applied in a solution state and dried to cover the surface of the substrate. The adhesiveness of the substrate to the sheet is extremely good by penetrating into the concave portions of the uneven parts, and on the other hand, the anti-peeling strength of the resin thin film is low against forces in the direction perpendicular to the sheet surface and the main surface to which the substrate is attached. weak,
When a force is applied to the sheet in a perpendicular direction to separate it from the first sheet, it can be peeled off very easily.

For this reason, the semiconductor elements can be arranged at predetermined intervals on the second sheet rather than on the stretched sheet as described above, and there is no need to take out the semiconductor elements from the sheet. It can be carried out extremely easily without any damage to the structure, is more efficient than conventional methods, has uniform properties, and can contribute to process automation. Although the above description has been made regarding a gap light emitting element, the present invention is not limited to this, and it goes without saying that the present invention can be applied to any type of element formed by dividing a semiconductor element from a semiconductor substrate.
