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 um. 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.
