What is a MOSFET?
A MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a semiconductor device. A MOSFET is most commonly used in the field of power electronics. A semiconductor is made of manufactured material that acts neither like a insulator nor a conductor. An insulator is a natural material that will not conduct electricity, such as a dry piece of wood. A conductor is a natural material that conducts or passes electricity. Metals are the most common examples of conductors. Semiconductor material from which devices like a MOSFET are made exhibit both insulation like properties and conduction like properties. Most importantly, semiconductors are designed such that the conduction or insulation properties can be controlled. The transistor is perhaps the best known semiconductor device. Early transistors use a technology referred to as bi-polar material. Pure silicon can be doctored or \”corrupted\”–a process that is referred to as \”doping\”. It is possible to make either p type (positive)
