Abstract:
A CMOSFET having a center line comprising:an insulating substrate;a first semiconductor layer of a first conductivity type and a second semiconductor layer of a second conductivity type formed on the insulating substrate, each of the first semiconductor layer and the second semiconductor layer having a center portion and two edge portions, and being spaced apart from each other by a predetermined distance;a third semiconductor layer of a second conductivity type formed to have a predetermined length extending from the edge portions of the first semiconductor layer toward the second semiconductor layer;a fourth semiconductor layer of a first conductivity type symmetrically formed with respect to the third semiconductor layer and the center line and having a predetermined length extending from the edges portions of the second semiconductor layer;a insulating layer formed on the entire surface of the first, second, third, and fourth semiconductor layers; anda gate electrode formed between the center portions of the first and second semiconductor layers, and being bounded by the first, second, third, and fourth semiconductor layers.
