Abstract
A method of making an EPROM transistor in a high density CMOS integrated circuit having a substrate to gate electrode material capacitor. The EPROM transistor is made using only the steps used to make the other components of the high density CMOS integrated circuit. The EPROM transistor is programmable at low voltages which high density CMOS transistors can handle.
