Mosfet short channel effect

WebShort-channel effects in thin-film silicon-on-insulator (SOI) MOSFETs are shown to be unique because of dependences on film thickness and body and back-gate (substrate) biases. These dependences enable control of threshold-voltage reduction, channel-charge enhancement due to a drain bias, carrier velocity saturation, channel-length modulation … Channel length modulation (CLM) is an effect in field effect transistors, a shortening of the length of the inverted channel region with increase in drain bias for large drain biases. The result of CLM is an increase in current with drain bias and a reduction of output resistance. It is one of several short-channel effects in MOSFET scaling. It also causes distortion in JFET amplifiers.

Second Order Effects in MOSFET - Ques10

WebThe channel strength and the threshold voltage can be changed through application of appropriate voltage to the body terminal of the MOSFET. This is known as the body effect. For gate voltages less than threshold voltage, current drops off exponentially and as feature sizes decrease the way MOSFETs behave in this region becomes important. WebHistorically, the short channel length limit was thought to be 500nm in the 70s, 250nm in the 80s, 100nm in the 90s when I was in grad school, and now 22nm is in production. So the channel length scaling potential was vastly underestimated, primarily because our ability to make transistor quality thin oxide was underestimated. WebShort-channel effects in MOSFET's.
