Abstract:
Transistors having improved breakdown voltages and methods of forming the same are provided herein. In one embodiment, a method of forming a transistor comprises the steps of: forming a drain and a source by doping a semiconductor with a first dopant type to form a first type of semiconductor, the drain and source being separated from one another, wherein the drain comprises a first drain region of a first dopant concentration adjacent a second drain region, such that at least a portion of the second drain region is positioned between the first drain region and the source, and further comprising forming an intermediate region by doping the semiconductor so as to form a second type of semiconductor intermediate the drain and source, the intermediate region spaced apart from the second drain region.
