Abstract

A method of forming sidewall spacers for a gate in a semiconductor device includes depositing a gate oxide layer over a gate and source/drain regions, and using a thermal anneal to oxidize silicon of the substrate and silicon of the gate after formation of the deposited oxide layer. A sidewall layer is deposited over the oxide layer following the oxidation, and the sidewall layer and oxide layer are patterned to form the sidewall spacers.
