Abstract(in English) | Degrading effects on BJT speed performance due to current- induced perturbation of the collector-base junction space-charge region(SCR)are analyzed.Inverse base-width modulation(IBWM)-- a widening of the quasi-neutral base width -- and SCR-width widening(SCRW)in highly-scaled HBT′s are identified as important m echanisms goveming device speed degradation at high currents. Simulations and transit-time evaluations of a SiGe-base HBT show that the speed degradation associated with IBWM is predominant. Simulations of a further scaled device show that SCRW can be the significant mechanism of speed degradation at high current densities. |
