TCAD Application CMOS Devices Example 

Sentaurus Technology Template: CMOS Processing 

The process flow represents a generic 90 nm technology node and is intended to serve as a convenient starting point for any deep submicron CMOS simulation project. The setup of the Sentaurus Workbench (SWB) project supports NMOS and PMOS devices, and allows for the simulation of structures with different gate lengths. Other variations can be included by adjusting the template. The Sentaurus Workbench template project also performs certain device simulations to extract key electrical parameters in order to facilitate customized calibration and optimization projects.
