Fundamentals of Silicon Processing and Microelectronic Devices

Fundamentals of Silicon Processing and Microelectronic Devices

This short course is designed to give an overview of how microelectronic devices are  fabricated on silicon wafer from ingot formation to an IC chip. If you are part of the semiconductor industry and working in areas such as design, layout, process, test, TCAD, reliability, yield enhancement, metrology or PFA, you need to have an overall picture and understanding of what is happing in the other areas  where it will make your role more effective. Here, you will learn how a silicon wafer looks like and how a generic CMOS process flow can be built on a wafer and how the different process modules can be integrated together. Also the electrical aspects (role of electrons and holes) of the devices are  discussed. The top view (Layout) and the  cross-section of all the process steps are presented. In conclusion the latest on transistor performance including metal gate are discussed.
