Abstract:
A transistor, such as laterally diffused (LD) transistor, having a band region below a drift well is disclosed. The band region and drift well are oppositely doped. The band region is self-aligned to the drift well. The band region reduces the depth of the drift well. A shallower drift well reduces risk of punch-through, improving reliability. In addition, the shallower drift well reduces the drain to body parasitic capacitance which improves performance.

Claim (Index 12):
The device of  claim 1 , wherein:\n the gate comprises first and second gates to serve as first and second fingers, wherein\n second sidewalls of the first and second gates are adjacent sidewalls with the second S/D region serving as a common second S/D region for the first and second gates, \n the first S/D region of the first and second gates comprises\n a first first S/D region disposed adjacent to a first sidewall of the first gate, and \n a second first S/D region disposed adjacent to a first sidewall of the second gate; \n \n the drift well disposed in the device region and encompasses the common second S/D region; and the self-aligned band region is disposed below the drift well.
