DC and RF performance of 0.25 μm p-type SiGe MODFET
Abstract
The DC and RF performance of 0.25 μm gateleagth p-type SiGe modulation-doped field-effect transistor (MODFFT) is reported. The hole channel consists of compressively strained Si0.3Ge0.7 layer grown on a relaxed Si0.7G0.3 buffer on a Si substrate. The combination of high-hole of 230 mS/mm was measured. A unity current gain cut-off frequency (fr) of 24 GHz and a maximum frequency of oscillation (fmax) of 37 GHz were obtained for these devices.
