Y shape gate formation in single layer of ZEP520A using 3D electron beam lithography
Single layer of ZEP520A are used to fabricate Y shape profile. 3D EBL with Monte Carlo simulation are used to achieve desired profile with Beamer software. 50nm Y shape gate have been successfully replicated using this method. Advantages of Y shape gate over T shape gate are discussed.
