Abstract
An embodiment of the present disclosure provides a semiconductor device. The semiconductor device includes an insulator formed on a top surface of a semiconductor substrate. The semiconductor device also includes a semiconductor layer containing a first region of a first conductivity type and formed on the insulator layer. The first region is a P+ region or an N+ region and has a volume of over 50-80% of that of the semiconductor layer. The semiconductor device further includes a second region of a second conductivity type in direct contact with the first region and forming a P-N junction with the first region. The second region has a doping concentration heavier than that of the first region. In addition, the semiconductor device includes a first metallization region in electrical contact with the first region and a second metallization region in electrical contact with the second region.
