Abstract
Plasma-enhanced deposition of a high-quality dielectric film for use as an intermetal dielectric in multilevel metal devices was demonstrated. Low-stress silicon dioxide films up to 2 mu m thick were deposited using tetraethylorthosilicate as a precursor. The films exhibit excellent step coverage, and the relatively low deposition temperature avoids hillock formation. Analysis of the films shows physical and electrical characteristics suitable for device applications.<>
