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 3):
The device of  claim 1 , further comprising a device isolation well disposed in the substrate, the device isolation well encompasses the device well and comprises first polarity type dopants to isolate the device well having second polarity type dopants from the substrate, wherein the second polarity type dopants are different from the first polarity type dopants.
