ABSTRACT:
The voltage characteristics of switching integrated circuits of the type disclosed in U.S. Patent No. 3,918,083 are improved by employing a mesa-type etch to physically separate the four vertical transistors. Interconnection may be carried out by wire bonding respective collector and emitter areas or, preferably, passivating materials are used to fill the etched grooves and interconnection is carried out by vapor deposition (e.g. planar) techniques.
