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 14):
The device of  claim 12 , wherein:\n the drift well comprises opposing drift well edges along a channel width direction of the device region; and the self-aligned band region comprises opposing band region edges along the channel width direction which extend farther under the first and second gates than the opposing drift well edges along the channel width direction, and wherein portions of the opposing band region edges extending farther under the first and second gates than the opposing drift well edges along the channel width direction extend almost to the top surface of the substrate.
