Abstract
Within a method for fabricating a semiconductor integrated circuit microelectronic fabrication, there is employed a planarizing method for forming, in a self aligned fashion, a patterned second gate electrode material layer laterally adjacent but not over a patterned first gate electrode material layer, such that upon further patterning of the patterned first gate electrode material layer and the patterned second gate electrode material layer there may be formed a first gate electrode over a first active region of a semiconductor substrate and a second gate electrode over a laterally adjacent second active region of the semiconductor substrate. The method is particularly useful within the context of complementary metal oxide semiconductor (CMOS) semiconductor integrated circuit microelectronic fabrications.
