摘要:
A method to achieve multiple threshold voltage (Vt) devices on the same semiconductor chip is disclosed. The method provides different threshold voltage devices using threshold voltage adjusting materials and a subsequent drive in anneal instead of directly doping the channel. As such, the method of the present disclosure avoids short channel penalties. Additionally, no ground plane/back gates are utilized in the present application thereby the method of the present disclosure can be easily integrated into current complementary metal oxide semiconductor (CMOS) processing technology.
