FILM FORMING PROCESS METHOD

摘要

A susceptor device is provided in a film- forming vessel (4) for semiconductor processing. The susceptor device includes a susceptor (16) having a top surface on which a wafer (W) to be processed is placed and a side surface extending downward from the top surface and a heater (18) provided in the susceptor (16) and serving to heat the wafer (W) through the top surface. The top and side surfaces of the susceptor (16) is coated with a CVD pre-coat layer (28). The pre-coat layer (28) has a thickness great enough to substantially saturate the amount of heat originated from the heater (18) and radiated from the top and side surfaces of the susceptor (16).
