Abstract:
A system for annealing a film on a substrate in a vacuum processing chamber comprisinga plasma enhanced chemical vapor deposition chamber having a substrate support centered in the chamber,a sidewall opening in the chamber for ingress and egress of a substrate to be processed in the chamber while mounted on the substrate support;a gas inlet manifold having a plurality of openings for the passage of processing gas into the chamber mounted opposed to and spaced from the substrate support;an RF power supply connected to said chamber to form a plasma therein from said processing gas to deposit a film on said substrate;a plurality of microwave generators mounted above said chamber, each connected to a waveguide mounted so as to direct microwaves uniformly over the surface of said film through a plurality of windows in said chamber, said microwaves having a frequency that is absorbed by said film and that is not absorbed by said substrate.
