Abstract

An apparatus for manufacturing photosensitive amorphous silicon objects comprises a pair of coaxial cylindrical electrodes inside a reaction tank of a plasma CVD device. A plurality of cylindrical substrates of an electrically conductive material disposed between these electrodes. A source gas is injected into the reaction tank through a plurality of inlets evenly spaced on the outer peripheral wall so that films of uniform quality can be produced efficiently.
