WebDec 3, 2003 · Inadequate dopant activation in the poly-Si gate results in carrier depletion at the gate/gate oxide interface (poly-depletion), which in turn degrades the device's drive … Webadditional depletion at the gate sidewall due to the fringing gate fields. This additional potential drop in short gate lengths can worsen the polydepletion effects especially for nonuniformly doped, sub-100 nm poly gate devices. Achieving less steep dopant gradients can be a potential solution to overcome this problem. REFERENCES
Webgate into the channel region.1 To reduce the high gate resis-tance and gate depletion problems, the active dopant density in the poly-Si gate material must be increased. In fact, the active dopant density must be greater than 1.8731020 cm23 at LG525 nm CMOS technology generation for the poly-Si gate depletion layer to be less than 25% of the ...
