发明名称 Method of pattern transfer
摘要 Pattern transfer is achieved by forming a first patterned hard mask layer with a circuit pattern and a plurality of dummy patterns on a substrate, forming a second pattern mask layer on the substrate, exposing the circuit pattern of the first pattern mask layer, and removing a portion of the substrate exposed by the first patterned mask layer, so as to transfer the circuit pattern to the substrate.
