A Benchmark Study Of Complementary-Field Effect Transistor (CFET) Process Integration Options Done By Virtual Fabrication


Four process flow options for Complementary-Field Effect Transistors (C-FET), using different designs and starting substrates (Si bulk, Silicon-On-Insulator, or Double-SOI), were compared to assess the probability of process variation failures. The study was performed using virtual fabrication techniques without requiring fabrication of any actual test wafers. In the study, Nanosheet-on-Nanoshe... » read more
