The first commercial transistors had a top-down structure made entirely of silicon: specifically, a polysilicon gate electrode, a thin (~20 nm) SiO 2 dielectric and a silicon bulk channel 1,2. In the ...

Advanced Micro Devices has developed two sets of next-generation transistors using different approaches that produce higher levels of performance than conventional transistors, the company said at the ...

Gate stack engineering has helped enable aggressive device scaling in silicon complementary metal–oxide–semiconductor technology. Two-dimensional (2D) materials are a potential replacement for silicon ...
