Abstract
A novel high side power MOSFET is presented, the design of which is based on a modified 600 V CMOS process developed for lateral power devices. Simulation results indicate that the blocking voltage is in excess of 550 V. A significant enhancement in the blocking voltage is realised by incorporating the source within an n-buffer layer. The improvement can be attributed to the increase in the `punch-through´ voltage of the vertical parasitic PNP transistor. The transient characteristic of turn on is also analysed
