Paper Abstract

In this paper we discuss several approaches for obtaining satisfactory coverage of plasma enhanced CVD TEOS, PETEOS, over severe topography in submicron and larger CMOS technologies. The problems inherent to PETEOS deposition are presented and several solutions are discussed. Adequate film contours can be obtained by the formation of a simple spacer plus a thick film etchback step. Other approaches discussed include a single deposition and etchback, multiple spacer formation, sloped metal profiles, planarization, and profile modification with physical sputtering.
