发明名称 MULTIPLE EXPOSURE LITHOGRAPHY METHOD INCORPORATING INTERMEDIATE LAYER PATTERNING
摘要 A method of patterning a semiconductor substrate includes creating a first set of patterned features in a first inorganic layer; creating a second set of patterned features in one of the first inorganic layer and a second inorganic layer; and transferring, into an organic underlayer, both the first and second sets of patterned features, wherein the first and second sets of patterned features are combined into a composite set of patterned features that are transferable into the substrate by using the organic underlayer as a mask.
