Paper Abstract

While waiting for EUV lithography to become ready for adoption, we need to create designs compatible with both EUV single exposures as well as with 193i multiple splits strategy for technology nodes 7nm and below needed to keep the scaling trend intact. However, the standard approach of designing standard cells in two-dimensional directions is no more valid owing to insufficient resolution of 193-i scanner. Therefore, we propose a standard cell design methodology, which exploits purely one-dimensional interconnect.
