ABSTRACT:
In a film-formation method for a semiconductor process, a silicon germanium film is formed on a target substrate by CVD in a process field within a reaction container. Then, a silicon coating film is formed to cover the silicon germanium film by CVD in the process field, while increasing temperature of the process field from the first temperature to a second temperature. Then, a silicon film is formed on the coating film by CVD in the process field.
