Paper Abstract

In conventional IC processes, the smallest size of any features that can be created on a wafer is severely limited by the pitch of the processing system. This approach is a key enabler of printing mask features on wafers without requiring new manufacturing equipment and with minor changes to existing manufacturing processes. The approach also does not require restrictions on the design of the chip. This paper will discuss the method and full-chip decomposition tool used to determine locations to split the layout. It will demonstrate examples of over-constrained layouts and how these configurations are mitigated. It will also show the reticle enhancement techniques used to process the split layouts and the Lithographic Checking used to verify the lithographic results.
