Abstract
In a thin-film formation process and system, a target and a substrate are placed in a sputtering space and a film-forming space, respectively, the pressure in the film-forming space is maintained at a pressure lower than the pressure in the sputtering space and a pressure sufficient for sputtered particles to move in the film-forming space with their mean free path which is longer than the distance between the grid plate and the substrate, and the target is sputtered to form a thin film on the substrate.
