Patent ID: 7514120

Claim:
A precoat film forming method of a film forming device having a loading table for loading an object to be processed inside, said method comprising: (1) raising the temperature of the loading table to a predetermined temperature; (2) maintaining the loading table constant at the predetermined temperature while feeding processing gas inside the film forming device to deposit a precoat TiN film on a surface of the loading table until the film reaches a minimum thickness within a range of film thickness, where radiation heat quantity from the loading table becomes constant; (3) loading the object onto the loading table, processing the object at a processing temperature lower than the predetermined temperature to form a TiN film on the object, and thereafter removing the object from the loading table; (4) idling the film forming device at the processing temperature until a next object is to be loaded onto the loading table for processing; and (5) repeating step (3) for the next object.
