SCALING OF BIPOLAR TRANSISTORS

摘要

Bipolar transistor structures, methods of designing and fabricating bipolar transistors, methods of designing circuits having bipolar transistors. The method of designing the bipolar transistor includes: selecting an initial design of a bipolar transistor (240 of FIG. 18); scaling the initial design of the bipolar transistor to generate a scaled design of the bipolar transistor (245); determining if stress compensation of the scaled design of the bipolar transistor is required based on dimensions of an emitter of the bipolar transistor after the scaling (250); and if stress compensation of the scaled design of the bipolar transistor is required then adjusting a layout of a trench isolation layout level of the scaled design relative to a layout of an emitter layout level of the scaled design (255) to generate a stress compensated scaled design of the bipolar transistor (260).
