Abstract
An integrated injection logic (IIL) structure including active devices, one of which is a switching transistor having base current injection from another active device where an epitaxial zone forms an emitter-base junction. A diffused zone in the epitaxial layer forms a collector for the switching transistor and an insulating structure defines perimeters of the collector-base junction and the emitter-base junction such that the widths thereof are about equal for maximizing current gain with minimal temperature dependence.
