Abstract
An integrated injection logic device formed on an insulating substrate. A lateral, load transistor and an adjacent, vertical switching transistor are formed in the semiconductor layer such that the collector region of the lateral transistor coincides with the base region of the switching transistor. The emitter of the switching transistor is located at the surface of the semiconductor injecting carriers downward into the collector. Isolated multiple collector contacts required for wired-AND logic are obtained by using separate Schottky-barrier contacts for each collector output.
