    摘要: A method of forming different structures of a semiconductor device using a single mask and a hybrid photoresist. The method includes: applying a first photoresist layer on a semiconductor substrate; patterning the first photoresist layer using a photomask to form a first patterned photoresist layer; using the first patterned photoresist layer to form a first structure of a semiconductor device; removing the first patterned photoresist layer; applying a second photoresist layer on the semiconductor substrate; patterning the second photoresist layer using the photomask to form a second patterned photoresist layer; using the second patterned photoresist layer to form a second structure of a semiconductor device; removing the second patterned photoresist layer; and wherein either the first or the second photoresist layer is a hybrid photoresist layer comprising a hybrid photoresist.
