System for Low-Energy Plasma-Enhanced Chemical Vapor Deposition

摘要

A system ( 10 ) for low-energy plasma-enhanced chemical vapor deposition comprising plasma source ( 100 ), deposition chamber ( 200 ) and gas distribution system ( 300 ) for semiconductor epitaxy on substrates up to 300 mm in size is described. The system ( 10 ) allows for fast switching from high to low deposition rates, and film thickness control at the monolayer level. It incorporates chamber self-cleaning and the provisions for selective epitaxial growth. The system ( 10 ) contains a broad-area plasma source ( 100 ) which can be used also in other applications, such as low-energy ion implantation and plasma treatment of surfaces.
