METHOD FOR MAKING A SEMICONDUCTOR DEVICE HAVING A HYPER-ABRUPT JUNCTION REGION INCLUDING A SUPERLATTICE
Last updated:
Abstract:
A method for making semiconductor device may include forming a hyper-abrupt junction region on a substrate and including a first semiconductor layer having a first conductivity type, a superlattice layer on the first semiconductor layer, and a second semiconductor layer on the superlattice layer and having a second conductivity type different than the first conductivity type. The first, second, and the superlattice layers may be U-shaped. The method may further include forming a gate dielectric layer on the second semiconductor layer of the hyper-abrupt junction region, forming a gate electrode on the gate dielectric layer, and forming spaced apart source and drain regions adjacent the hyper-abrupt junction region.
