Method to define multiple layer patterns with a single exposure by charged particle beam lithography
摘要:
The present disclosure provides a method that includes forming a first patternable material layer on a substrate; forming a second patternable material layer over the first patternable material layer; and performing a charged particle beam lithography exposure process to the first patternable material layer and the second patternable material layer, thereby forming a first latent feature in the first patternable material layer and a second latent feature in the second patternable material layer.
