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.

EPROM in high density CMOS having added substrate diffusion

A method of making an EPROM transistor in a high density CMOS integrated circuit having a gate electrode to metallization 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.

Method of making EPROM in high density CMOS having metallization

A method of making an EPROM transistor in a high density CMOS integrated circuit having a poly to poly capacitor and including two layers of polysilicon. 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 the low voltages which high density CMOS transistors can handle.
