METHOD FOR FORMING A LITHOGRAPHY PATTERN |
摘要 |
A method of lithography patterning includes forming a first material layer on a substrate, the first material layer being substantially free of silicon, and forming a patterned resist layer including at least one opening therein above the first material layer. A second material layer containing silicon is formed on the patterned resist layer and an opening is formed in the first material layer using the second material layer as a mask.
