    摘要： Semiconductor device structures and related fabrication methods are provided. An exemplary semiconductor device structure includes a first region of semiconductor material having a first conductivity type and a first dopant concentration, a second region of semiconductor material having a second conductivity type overlying the first region, a drift region of semiconductor material having the first conductivity type overlying the second region, and a drain region of semiconductor material having the first conductivity type. The drift region and the drain region are electrically connected, with at least a portion of the drift region residing between the drain region and the second region, and at least a portion of the second region residing between that drift region and the first region. In one or more exemplary embodiments, the first region abuts an underlying insulating layer of dielectric material.

    摘要： A device includes a semiconductor substrate, source and drain regions in the semiconductor substrate, a channel region in the semiconductor substrate between the source and drain regions through which charge carriers flow during operation from the source region to the drain region, and a drift region in the semiconductor substrate, on which the drain region is disposed, and through which the charge carriers drift under an electric field arising from application of a bias voltage between the source and drain regions. A PN junction along the drift region includes a first section at the drain region and a second section not at the drain region. The drift region has a lateral profile that varies such that the first section of the PN junction is shallower than the second section of the PN junction.
