ABSTRACT:
An integrated circuit is made that includes an insulated gate transistor and a buried contact. The buried contact is used to divide an active device area in two discrete parts, that are doped during source-drain doping in other active device mesas of the integrated circuit. Discrete contacts to these regions, along with the buried contact, provide an additional type of electrical component in the integrated circuit, such as a bipolar lateral transistor.
