发明名称 SEMICONDUCTOR DEVICES WITH REDUCED STI TOPOGRAPHY BY USING CHEMICAL OXIDE REMOVAL
摘要 A thermal oxide may be removed in semiconductor devices prior to performing complex manufacturing processes, such as forming sophisticated gate electrode structures, by using a gaseous process atmosphere instead of a wet chemical etch process, wherein the masking of specific device regions may be accomplished on the basis of a resist mask.
