Paper Abstract

This paper reports on the integrity of thin N2O oxides in tungsten polycide (poly-Si/WSi2 stack) gated MOS structures, which was characterized by their charge-to-breakdown (QBD). In this study, WSi2 films were formed either by chemical vapor deposition (CVD) or sputtering. It is found that with CVD-WSi2 gate, N2O gate oxide has a much degraded integrity in terms of high infant-mortality rate and low QBD values compared with the sputtered WSi2 gate.
