Abstract:
1. A method of depositing a silicon thin film on a substrate by using a plasma CVD apparatus, comprising: holding the substrate having an area not smaller than 1,200 cm 2 and having a conductive film formed thereon with a substrate holder; disposing the substrate to face an electrode; and depositing a silicon thin film on the substrate under a power density of 100 mW/cm 2 or more, wherein the conductive film is removed from a peripheral region of the substrate, and the substrate holder is brought into contact with the peripheral region of the substrate from which the conductive film is removed so as to permit the substrate holder to hold the substrate, wherein the substrate holder is electrically insulated from the conductive film formed on the surface of the substrate.
