ABSTRACT:
Disclosed is a process for depositing a conformal polymer coating on selected areas of a silicon substrate. The substrate is first exposed through a mask to a gaseous plasma so as to form a film of desired pattern, the plasma comprising a compound having strong electron donating characteristics. Then, the patterned film and the remaining substrate not covered by the film are exposed to the vapor of a monomer, which condenses and polymerizes on the exposed substrate surfaces, but not on the film. The film serves to inhibit substantial deposition of the coating, so as to provide a selective deposition, where the coating is formed only on those areas of the substrate where desired.
