What This Document Is
This document presents detailed results from process simulations conducted using TSUPREM4, a widely-used software tool in microfabrication. Specifically, it focuses on the fabrication of a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) device, a fundamental building block of modern electronics. The material originates from EE143 Microfabrication Technology at the University of California, Berkeley, Fall 2002, and was prepared in courtesy of Daewon Ha. It’s a collection of simulation outputs visualizing key stages in the MOSFET manufacturing process.
