Abstract :
Reverse short-channel effect modulation by poly-Si doping level is explained in terms of the effective oxide thickness change due to poly-Si depletion. This modulation is not accounted for in the conventional theories of RSCE and should be taken into consideration in design of submicron CMOSFETs
