| Abstract: | Matlab numerical analysis, coupling with base current components in polysilicon emitter bipolar transistors, was adopted to illustrate the basic principles and mathematical methods in exact base current component extraction in detail. This method was employed to extract and analyse the base current component with different ideality factor and the variation trends in high forward current stressed polysilicon emitter biapolar transistors. The electrical parameters degradation characteristics and mechanisms were also discussed. This ideality factor extraction method was widely appropriate for various bipolar transistor technologies. |
