Abstract:
A semiconductor device manufacturing apparatus that uses a thermal CVD reaction to deposit a film onto a substrate, said apparatus having a vaporizer for vaporizing a raw material to form a vapor phase deposition material, and a power supply for supplying a d.c. electrical potential to said substrate or said film deposited thereupon for attracting said vapor phase material,wherein said power supply supplies said d.c. electrical potential to said substrate or said film deposited thereupon, either directly or indirectly, and said power supply further comprises a d.c. electrical potential controller which controls said potential to be supplied to said substrate or said film deposited thereupon; and wherein electrode terminals are provided on peripheral area of either said substrate or a region on which said film being deposited on said substrate, and said electrode terminals comprise a plurality of pairs of two electrode terminal units, each one of said pairs comprising two electrode terminal units, a first electrode terminal unit and a second electrode terminal unit which being oppositely arranged with interposing an area of said substrate on which said film will be deposited, therebetween.
