Abstract(in English)	We have achieved advanced high-frequency performance in small-scaled InGaP/GaAs HBT's due to the further reduction of the parasitic capacitance by refining the device design and the process technology. An f_T of 156 GHz and f_ of 255 GHZ were achieved for an HBT with an emitter size S_E of 0.5×4.5μm^2 at a collector current I_C of 3.5 mA, and an HBT with S_E of 0.25×1.5μm exhibite f_T of 114 GHz and f_ of 230 GHz at I_C of 0.9 mA. A 1/8 static frequency divider using these HBT's operated at a maximum toggle frequency of 39.5 GHz with power consumption per flip-flop of 190 mW.
