Integrated injection-logic semiconductor circuit

摘要

An integrated injection-logic (IIL) semiconductor circuit with a transverse transistor and a vertical transistor is created which exhibits an additional area (19) in the vicinity of the collector areas (16, 17) of the vertical transistor (Q1) and which is arranged in such a manner that its breakdown voltage is less than that for the collector areas. The additional area (19) is electrically connected to the base area (14) of the vertical transistor (Q1), thus eliminating damage due to voltage surges. <IMAGE>
