Abstract:
1. A semiconductor device comprising: a string array including T bipolar junction transistors, where T is an integer and wherein the string array comprises: a common collector region for the T bipolar junction transistors; a common base region for the T bipolar junction transistors; and a plurality of emitters, one emitter for each of the T bipolar junction transistors, wherein the plurality of emitters includes emitter contacts; B base contacts for the T bipolar junction transistors, the B base contacts electrically coupling the common base region, where B is an integer and is less than T; a logic region including one or more logic transistors; and an isolation region for isolating the logic transistors, wherein the emitter contacts are offset from a center of an array spacing established by the string array and the plurality of emitters.
