Abstract:
1. A method of fabricating a semiconductor device on a semiconductor-on-insulator substrate comprising a support layer, a buried insulator layer overlying the support layer, and a layer of semiconductor material overlying the buried insulator layer, the method comprising: forming epitaxially grown semiconductor material overlying the layer of semiconductor material, the epitaxially grown semiconductor material having a first conductivity type, and at least a portion of the epitaxially grown semiconductor material serving as a first semiconductor region of the semiconductor device; forming a second semiconductor region in the epitaxially grown semiconductor material, the second semiconductor region located above the first semiconductor region and having a second conductivity type; forming a third semiconductor region in the epitaxially grown semiconductor material, the third semiconductor region located above the second semiconductor region and having the first conductivity type; forming a fourth semiconductor region in the epitaxially grown semiconductor material, the fourth semiconductor region located above the third semiconductor region and having the second conductivity type; and forming a fifth semiconductor region in the epitaxially grown semiconductor material, the fifth semiconductor region extending through the fourth semiconductor region and the third semiconductor region to the second semiconductor region, and having the second conductivity type.
