Opis:: Measurements of 1/f noise in Si and Si0.64Ge0.36 PMOSFETs have been compared with theoretical models of carrier tunnelling into the oxide. Reduced noise is observed in the heterostructure device as compared to the Si control. We suggest that this is primarily associated with an energy dependent density of oxide trap states and a displacement of the Fermi level at the SiO2 interface in the heterostructure relative to Si. The present study also emphasizes the important role of transconductance enhancement in the dynamic threshold mode in lowering the input referred voltage noise.

Opis:: Measurements of current drive in p-Si1-xGex MOSFETs, with x = 0.7, 0.8 reveal an enhancement ratio of over 2 times as compared to a Si device at an effective channel length of 0.55 žm. They also show a lower knee voltage in the output I-V characteristics while retaining similar values of drain induced barrier lowering, subthreshold swing, and off current for devices with a Sb punch-through stopper. For the first time, we have quantitatively explained the low-frequency noise reduction in metamorphic, high Ge content, SiGe PMOSFETs compared to Si PMOSFETs.
