ABSTRACT:
The method entails laying out NPN transistors in a bipolar integrated circuit in a manner which prevents crystal dislocations from making the transistor unreliable. The long edges of the collector contacts are aligned in a direction substantially perpendicular to the direction between the collector contact and the emitter-base junction.
