Abstract:
A lateral double-diffused metal-oxide-semiconductor transistor includes a silicon semiconductor structure and a vertical gate. The vertical gate include a (a) gate conductor extending from a first outer surface of the silicon semiconductor structure into the silicon semiconductor structure and (b) a gate dielectric layer including a least three dielectric sections. Each of the at least three dielectric sections separates the gate conductor from the silicon semiconductor structure by a respective separation distance, where each of the respective separation distances is different from each other of the respective separation distances.

Claim (Index 19):
A method for forming a vertical gate of a lateral double-diffused metal-oxide-semiconductor (LDMOS) transistor, the method comprising the steps of:\n forming a trench in a silicon semiconductor structure; forming a first dielectric liner in the trench; after the step of forming the first dielectric liner, filling the trench with a sacrificial material; removing a first portion of the sacrificial material to expose a first portion of the first dielectric liner; removing the first portion of the first dielectric liner; removing a remainder of the sacrificial material; forming a second dielectric liner at least where the first portion of the first dielectric liner was removed; and filling the trench with a conductive material to form a gate conductor.
