Symmetrical npn transistors with a sidewall base contact structure (SICOS) were developed and high cutoff frequencies of 14 GHz in downward and 4 GHz in upward operation were obtained. Using these transistors, high speed ECL circuits, frequency divider circuits and multiplier circuits are constructed and their performances are nearly equal to that of GaAs devices.
