Towards MuGFETs: A power reduction perspective

The progress towards making efficient chips, in terms of area, speed and power continues to remain a major concern of every silicon industry. The various effects that become prominent at nanometer level hinders this progress. This is a paper that looks into: scaling, its effects (short-channel effects, as it is called) and compares scaled single gate and scaled multiple gate FETs on important properties. The use of scaled multiple gate MOSFETs (MuGFETs) ensures better gate control and alpha-power model demonstrates reduction in time delay in MuGFETs, than in scaled single gate FETs. This shows that the short-channel effects are overcome by scaled MuGFETs, thereby not only facilitating higher packaging density, but also reducing power consumption and at the same time improving switching performance.
