Abstract:
1. A semiconductor device comprising: a body region in a substrate, the body region being of a first conductivity type; a gate pattern disposed on the body region, the gate pattern comprising a linear portion extending longitudinally in a first direction in an X-Y plane, and a bending portion extending from one end of the linear portion and bending from the first direction in the X-Y plane; and a channel region located beneath the gate pattern, wherein the linear portion of the gate pattern has a uniform width, and the channel of the semiconductor device has a first length in a first portion of the channel region located beneath the linear portion of the gate pattern, the first length being equal to the width of the first portion of the channel region, whereby the width of the first portion of the channel region is a first dimension thereof in a second direction perpendicular to the first direction in the X-Y plane, the channel of the semiconductor device has a second length in a second portion of the channel region located beneath the bending portion of the gate pattern, the second length being equal to the width of the second portion of the channel region at one point therealong, whereby the width of the second portion of the channel region is a second dimension thereof in a direction different from each of the first and second directions in the X-Y plane, and the second channel length is greater than the first channel length.
