Abstract
In a semiconductor device, pining regionsare disposed along the junction portion of a drain regionand a channel forming regionlocally in a channel width direction. With this structure, because the spread of a depletion layer from a drain side is restrained by the pining regions, a short-channel effect can be restrained effectively. Also, because a passage through which carriers move is ensured, high mobility can be maintained.
