Abstract
A semiconductor device includes a semiconductor substrate, an insulating layer, a semiconductor layers and a silicide layer. The insulating layer is formed on the semiconductor substrate. The semiconductor layer is formed on the insulating layer and includes a polycrystalline silicon. The silicide layer is formed on the semiconductor layer. The semiconductor layer has a first semiconductor part and a second semiconductor part. The first semiconductor part includes a first semiconductor region of a first conductivity type, and a second semiconductor region of a second conductivity type. The second semiconductor part is adjacent the second semiconductor region. In a width direction of the first semiconductor part, a second length of the second semiconductor part is greater than a first length of the first semiconductor part. A distance between the first and second semiconductor regions is 100 nm or more in an extension direction in which the first semiconductor region extends.
