Question

Explain short-channel effects in a MOSFET.

Answer 1

The Short-channel effect. In electronics,short-channel effects occur in MOSFETs in which there the channel length is comparable to that of the depletion-layer widths of the source and drain junctions. These effects include, in particular, drain-induced barrier lowering, velocity saturation, and hot carrier degradation.

Answer 2

The main drives for reducing the size of the transistors, i.e., their lengths, is increasing speed and reducing cost. When you make circuits smaller, their capacitance reduces, thereby increasing operating speed. In the same token, smaller circuits allow more of them in the same wafer, dividing the total cost of a single wafer among more dies.

However, with great reduction come great problems, in this case in the form of unwanted side effects, the so called short-channel effects. When the channel of the MOSFET becomes the same order of magnitude as the depletion layer width of source and drain, the transistors start behaving differently, which impacts performance, modeling and reliability. These effects can be divided among the following

hop this helped sorry for the last one that was off te wickapedia this one is all from me head plz mark brainliest
