Process for forming a film on a substrate having a field emitter

摘要

A process for forming a film on a substrate having a field emitter is disclosed. The substrate and field emitter are cleaned by hydrogen plasma to remove the impurities. Next, a silicon carbide film is selectively formed over said field emitter. A negative bias voltage of about 150 V to about 300 V is applied to substrate for increasing the nucleation sites of said silicon carbide film. Afterward, the negative bias voltage is stopped so as to grow a carbon-containing film from said silicon carbide film.
