| 摘要 |
A metal-oxide-semiconductor (MOS) device is formed comprising a semiconductor layer of a first conductivity type, a first source/drain region of a second conductivity type formed in the semiconductor layer, and a second source/drain region of the second conductivity type formed in the semiconductor layer and spaced apart from the first source/drain region. The MOS device further comprises a first gate formed proximate an upper surface of the semiconductor layer and at least partially between the first and second source/drain regions, the first gate comprising a plurality of sections spaced apart from one another, and a second gate formed proximate the upper surface ofthe semiconductor layer, the second gate comprising a first end formed between at least two of the plurality of sections of the first gate and a second end opposite the first end formed above at least a portion of the first gate, the second end being wider than the first end, the first and second gates being electrically isolated from one another.
