Abstract:
The present invention is directed to a semiconductor chip comprising a high voltage device and a low voltage device disposed thereon. The chip may be formed in several different configurations. For example, the semiconductor chip may include a NPN bipolar transistor, PNP bipolar transistor, a diode, an N channel DMOS transistor and the like. the first doped well being configured as a base of the DMOS transistor, a P channel DMOS transistor and the like. These and other embodiments are described in further detail below.
