Abstract:
1. A MOSFET device, comprising: a ground plane formed of a monocrystalline Si based material, wherein said ground plane has dopant impurities of a first type with a concentration of between about 1×10 a Si based body layer epitaxially disposed on said ground plane and having an interface with said ground plane, wherein said body layer has a thickness of between about 2 nm and 7 nm, wherein said body layer has dopant impurities of a second type with a concentration of between about 5×10 a gate insulator layer disposed over said body layer; a gate disposed over said gate insulator layer, wherein said gate comprises a metal with a mid-gap workfunction, wherein said metal is in direct contact with said gate insulator layer, wherein said gate has a length of less than about 40 nm; and a source and a drain, wherein said source and said drain have dopant impurities of said second type with a concentration of between about 5×10
