Patent ID: 11923429
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. A semiconductor device comprising:
a device region disposed in a semiconductor substrate;
a first source/drain region and a second source/drain region disposed in the device region, wherein both the first source/drain region and the second source/drain region have a first doping type, wherein the first source/drain region is laterally spaced from the second source/drain region, and wherein a portion of the device region extends laterally from the first source/drain region to the second source/drain region; and
a gate disposed over the device region, wherein the gate comprises a first doped region, a second doped region, and a third doped region, wherein both the first doped region and the third doped region have the first doping type, wherein the second doped region has a second doping type opposite the first doping type, and wherein the second doped region is disposed laterally between the first doped region and the third doped region.
