させることを目的とする。In order to uniformly form a film on the surface to be formed, the present invention generates an electric field, that is, lines of electric force, approximately parallel to the surface of the substrate to be formed, and an equipotential surface perpendicular to the surface, thereby causing a plasma gas phase reaction. This plasma, especially the positive column, is surrounded by a surrounding insulator such as a glass or alumina ceramic plate to electrically shield it from a metal reaction vessel such as stainless steel.
The purpose is to form a film with a uniform thickness by generating a parallel electric field similar to that at the center of the plasma at the edges (periphery).

つきの範囲に有せしめることができる方法がなかった。Conventionally, in the plasma vapor phase reaction (hereinafter referred to as PCVD) method, a pair of electrodes are arranged in parallel to form a parallel plate type electrode, and a plasma discharge is generated between the electrodes using a glow discharge method to form a semiconductor film, etc. was going on. Further, heating of this substrate was provided so that radiant heat was applied to the back surface of the substrate perpendicularly to the substrate. For this reason, only one substrate having the same area as the substrate could be heated with one heater. In addition, in this PCVD method, since the positive column generated by plasma tends to spread throughout the entire space inside the reaction vessel, the substrate is not disposed within the positive column but is placed closely on one of the electrodes. (perpendicular to the electric field)
There is no other way to make the coating uniform within ±5% of variation other than by changing the structure.

不向きであるという欠点を有する。However, in this method, the surface on which the electrode is formed cannot be made larger than the electrode area (3). Therefore, it has the disadvantage of being unsuitable for mass production.

A method of arranging them in a forest with a distance of 6 cm is known.

板に被膜形成を行うことができるという特長を有する。That is, in the so-called floating plasma vapor phase reaction method (hereinafter referred to as PPCVD method) in which a vapor phase reaction is performed by separating the substrate electrically from any electrode, it has the advantage that a film can be formed on a large number of substrates. .

ごときものであった。Therefore, compared to the conventional method of disposing a substrate on one electrode of a parallel plate type electrode, productivity could be increased by 5 to 20 times. However, the uniformity of the film thickness obtained by such PPCVD method was as shown in FIG. 1 as an example.

Furthermore, as shown in (B), (D>, and (E)), the central part of the electrode was thick, and the electrode end part was thin.

たため、かかる不均一性被膜(5)
が形成されてしまったためであることが判明した。As a result of further investigation of the invention of the PPCVD method by a dud student, we found that a 1-3 cm wide area was formed at the top and bottom of the space above the part surrounded by the insulating material (quartz) in the peripheral part (38), <38'). Because there are gaps (73) and (73'>, and a conductive stainless steel container is placed at ground level outside of these gaps, plasma leaks to the outside from here. This leakage causes the electric field in the reaction space to It was found that this was due to the formation of such a non-uniform film (5) due to the disturbance of the electric lines of force.

The present invention satisfies these objects and at the same time has a structure in which the gap (73) in the reaction space is substantially eliminated by the insulating cover of the heater.

We propose a multi-chamber type PCVD method in which reaction vessels are connected via separation parts when laminating and forming a bond on a substrate, as shown in FIG. 2.

By separating each other from each other, the film thickness is uniform at the top, bottom, and around the center 1 of the substrate, which is arranged approximately parallel to the film formation surface, and the film quality is homogeneous. It is meant to improve.

61), <51> or (62), <521>, and reactive gas supply nozzles (17>, (18) and exhaust nozzles (17') (1B') were provided. That is,
The structure is such that the outside of the electrode is wrapped in an insulating hood. Furthermore, in order to confine the reaction space between the hoods, the outer periphery is h'? Surrounded by 3 edges (3B>, <38'). In other words, the space surrounded by the insulator holder, that is, the confined space (8
) By supplying the active gas that causes a plasma reaction only to the cylindrical space (6), <8) of the reaction space, the reaction that has turned into plasma is generated in the entire space inside the chamber (reaction vessel><101>, (102)). This prevents the product from diffusing and spreading.Also, Figure 3 shows a cross-sectional view of Figure 2, showing the front (left side of the drawing) and rear (right side of the drawing) of the reaction vessel.
An opening/closing door was provided, and heating means (13), <13') using a halogen lamp or the like was provided on the inner surface of this door. This way, even if the lamp breaks down, it will be easy to replace and it will be safe! During this process, contamination of the inner surface of the reaction vessel (103) could be prevented.

法はきわめて有効であることが判明した。This improvement in efficiency is due to the fact that the film thickness at the periphery of a large-area substrate can be reduced from the conventional 5000±3000 to 5000±250, which is the optimal film thickness for one layer (20
), and similarly, compared to conventional P- or N-type semiconductor layers where the film thickness varied too much and sufficient open-circuit voltage could not be produced, the method of the present invention was able to make the film thickness extremely uniform. As a result, the open voltage for one element was 0.85 to 0.9V (0.87±0.02V), but the short circuit current was as large as 18±2mA/ctA.
In addition, the PF was as large as 0.60 to 0.70, and its variation was small within panels and batches, proving that the method of the present invention is industrially very effective.
