Abstract
A method for forming a semiconductor device with a doped channel-region, and the device formed therefrom. In one embodiment, the method invention is comprised of two principal steps. The first step is to provide a semiconductor substrate to which the following process steps can be performed. The second step is to create a doping profile into the channel-region of the semiconductor substrate. The doping profile is created by a) performing a first doping implantation with a first dopant in a first concentration to a first depth within the semiconductor substrate, and b) performing a second doping implantation with a second dopant in a second concentration to a second depth within the semiconductor substrate.
