  A special type of metal oxide semiconductor field effect transistor (MOSFET) which is designed to handle the significant power level is known as power MOSFET. A trench gate power MOSFET market is an attempt to achieve the high power drive capability by making a complete chip to vertically conduct the current from one surface to another. This is accomplished by stacking millions of trenches on a chip which are deep enough to cross the opposite doped ‘body’ region below the top surface. Each trench has a gate electrode and gate dielectric which control the current conduction in their vicinity by virtue of the field effect. Like any other MOSFET, a trench gate power MOSFET also contains the gate, source, drain, channel, and body regions as well as exhibits a current flow in vertical direction. It has a LDD (lightly doped drain) region between the drain and the channel making it capable of sustain the large voltage in an OFF-state condition.  The low resistance of a trench gate...
