Abstract:
1. A method comprising: defining a well region within a substrate with a first dopant; defining a source region in the substrate outside of the well region, and a drain region within the substrate and within the well region, with a second dopant; defining a first gate region within the substrate and within the well region with a third dopant; forming a dielectric layer on the substrate between the source region and the well region; defining a first doped region within the substrate and between the dielectric layer and the first gate region with the second dopant, the first doped region also being within the well region; defining a second doped region within the substrate, outside of the well region, and between the dielectric layer and the first doped region with the second dopant; forming a first electrically conductive layer on the dielectric layer; and forming a second electrically conductive layer on the substrate and contacting both the first and second doped regions.
