Abstract
A plasma CVD system has a reactor which can be evacuated, a substrate holding means in the reactor, a material gas feed means for feeding into the reactor a material gas for plasma CVD, a high-frequency power supply means for supplying an electrode high-frequency power of 30 MHz to 600 MHz, generated by a high-frequency power source, and means for exhausting gas remaining in the reactor after the reaction. The high-frequency power is supplied to produce a plasma across a substrate in the reactor to form a deposited film on the substrate, and the phase of reflected power is adjusted on the electrode at a side opposite the feeding point. High-quality deposited films having very uniform film thickness and homogeneous film quality can be formed at a high rate and stably on large-area substrates having any shapes.
