Abstract

An improved method and apparatus for forming a plasma-polymerized methylsilane (PPMS) photo-sensitive resist material includes the steps of pressurizing the chamber to between about 1 to about 2 Torr, heating the substrate to between about 50.degree. C. and about 200.degree. C., and plasma-polymerizing the precursor methylsilane gas to deposit a stable film having high-photosensitivity at high deposition rates.
