0.3-μm Gate-length Metamorphic AIInAs/GalnAs HEMTs on Silicon Substrates by MOCVD
Fabrication and performance of high-frequency 0.3-nm gate-length depletion-mode metamorphic Alo.50Ino.soAs/Gao.47Ino.53As high electron mobility transistors (mHEMT) grown by Metalorganic Chemical Vapor Deposition (MOCVD) on n-type silicon substrates is reported. Using a combined optical and e-beam photolithography technology, submicron mHEMT devices on Si have been achieved. A maximum trans-conductance up to 739mS/mm was measured. The unity current gain cut-off frequency (fT) and the maximum oscillation frequency (fmax) were 72.4 and 77.3GHz, respectively. An input capacitance to gate-drain feedback capacitance ratio, Cgs/Cgd, of 6.8 and a voltage gain, gm/go, of 6.9 are observed in the device.
