MOSFET Construction and Characteristics
MOSFET Construction and Characteristics: Figure 9-28 shows the MOSFET Construction and Characteristics of a metal oxide semiconductor FET (MOSFET), also known as an insulated gate FET. Starting with a high-resistive p-type substrate, two blocks of heavily-doped n-type material are diffused into the substrate, and then the surface is coated with a layer of silicon dioxide. …
