  • Patent number: 6737123
    Abstract: A silicon-based film is formed superimposing a direct-current potential on the high-frequency power to set the potential of the high-frequency power feed section to a potential which is lower by V1 than the ground potential; the V1 satisfying |V2|≦|V1|≦50×|V2|, where V2 is the potential difference from the ground potential, produced in the electrode in the state the plasma has taken place under the same conditions except that the direct-current potential is not superposed on the high-frequency power and the electrode is brought into a non-grounded state. This can provide a silicon-based film having superior characteristics at a high film formation rate, and a semiconductor device making use of this silicon-based film, having superior adherence, environmental resistance, and can enjoy a short tact time at the time of manufacture.
