摘要:
Structure and methods of fabrication are disclosed for an enhanced FET devices in which dopant impurities are prevented from diffusing through the gate insulator. The structure comprises a Si:C, or SiGe:C, layer which is sandwiched between the gate insulator and a layer which is doped with impurities in order to provide a preselected workfunction. It is further disclosed how this, and further improvements for FET devices, such as raised source/drain and multifaceted gate on insulator, MODFET on insulator are integrated with strained Si based layer on insulator technology.
