Semiconductor design is a multi-billion dollar industry, with huge investments at stake in every new design. To save money, simulation has become a critical part of the semiconductor design cycle. This book arms the designer with the mathematical and physical knowledge needed to implement effective semiconductor simulations. The accompanying CD-ROM features the fully-functioning SimGen simulation software for modeling semiconductor devices and applications.The book begins with an introduction to the essentials of physics and numerical analysis as they relate to semiconductor simulation. It introduces both electromagnetism and transport processes. Part II focuses on the SimGen software, which makes it dramatically easier to solve semiconductor transport equations. Part III reviews the analytic theory associated with each major semiconductor device, and compares the theory to simulations. Finally, Part IV introduces more advanced topics in device simulation, including mixed-mode simulations and simulation of power semiconductor devices.For all semiconductor device designers and researchers, both experimental and theoretical.
