Method of forming film on semiconductor substrate in film-forming apparatus
First Claim
1. A method of forming a thin film on a substrate in a film-forming apparatus comprising upper and lower electrodes in a processing chamber, between which radio-frequency power is applied, wherein a film-forming process is conducted at a designated temperature on a substrate loaded on the lower electrode which is provided with a heater, and in one lot, at least one substrate is processed, said method comprising:
- at the end of a stand-by period in which no film forming is performed between lots and before initiating the film-forming process, heating the lower electrode to a temperature close to the temperature for film forming.

Abstract
A thin film is formed on a substrate in a film-forming apparatus which has upper and lower electrodes between which radio-frequency power is applied in a processing chamber, and a heater is used to heat the lower electrode on which the substrate is loaded. In one lot, at least one substrate is processed. The electrode is heated at the end of a stand-by period between lots and before starting the film-forming process.
