  • EPROM in high density CMOS having added substrate diffusion
    Patent number: 5969382
    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.
    Type: Grant
    Filed: November 3, 1997
    Date of Patent: October 19, 1999
    Assignee: Delco Electronics Corporation
    Inventors: John Robert Schlais, Randy Alan Rusch

  • EPROM in double poly high density CMOS
    Patent number: 5872034
    Abstract: 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.
