Abstract
This disclosure relates to an integrated circuit using an insulated gate field effect transistor of the punch-through type for use in high speed electronic computation. Until now the punch-through phenomena has been considered a defect in the insulated gate field effect transistor. However, the effective utilization of the punch-through phenomena is achieved by using a specially designed insulated gate field effect transistor having a selected structure or material.
