"The invention provides a photoelectric conversion element manufacturing apparatus that forms a semiconductor stack film on a substrate by using microwave plasma CVD. The apparatus includes a chamber which is a enclosed space containing a base, on which the a subject substrate for thin-film formation is mounted, a first gas supply unit which supplies plasma excitation gas to a plasma excitation region in the chamber, a pressure regulation unit which regulates pressure in the chamber, a second gas supply unit which supplies raw gas to a plasma diffusion region in the chamber, a microwave application unit which applies microwaves into the chamber, and a bias voltage application unit which selects and applies a substrate bias voltage to the substrate according to the type of gas."
