Abstract
Semiconductor device and method for fabricating the same, is disclosed, which can maintain a threshold voltage constant despite of decreased channel width, the device including a first, and a second conductive type wells in a substrate, a first, and a second gate insulating films on the first, and the second conductive type wells, a first gate electrode on the first gate insulating film, the first gate electrode being doped with a second conductive type except for edges of the first gate electrode in a channel width direction counter doped with a first conductive type, a second gate electrode on the second gate insulating film, the second gate electrode being doped with a first conductive type except for edges of the second gate electrode in a channel width direction counter doped with a second conductive type, and isolating regions formed between the first, and second conductive type wells, the first, and second gate insulating films, and the first, and second gate electrodes.
