A new process, electron cyclotron resonance (ECR) microwave plasma oxidation, has been developed to produce a gate quality oxide directly on SiGe alloys. One mu m Al gate Si0.88Ge0.15 p-metal-oxide-semiconductor field-effect-transistors (pMOSFET's) with ECR-grown gate oxide have been fabricated. It is found that saturation transconductance increases from 48 mS/mm at 300 K to 60 mS/mm at 77 K. Low field hole mobilities of 167 cm(2)/V-s at 300 K and 530 cm(2)/V-s at 77 K have been obtained.
