ABSTRACT:
A system and a method are disclosed for manufacturing double epitaxial layer N-type lateral diffusion metal oxide semiconductor transistors. In one embodiment two N-type buried layers are used to minimize the operation of a parasitic PNP bipolar transistor. The use of two N-type buried layers increases the base width of the parasitic PNP bipolar transistor without significantly decreasing the peak doping profiles in the two N-type buried layers. In one embodiment two N-type buried layers and one P-type buried layer are used to form a protection NPN bipolar transistor that minimizes the operation of parasitic NPN bipolar transistor. The N-type lateral diffusion metal oxide semiconductor transistors of the invention are useful in inductive full load or half bridge converter circuits that drive very high current.
