  • Radiation hardened CMOS structure using an implanted P guard structure and method for the manufacture thereof
    Patent number: 5220192
    Abstract: A radiation hardened NMOS transistor structure suited for application to radiation hardened CMOS devices, and the method for manufacturing it is disclosed. The new transistor structure is characterized by "P" doped guard bands running along and immediately underlying the two bird's beak regions perpendicular to the gate. The transistor and the CMOS structure incorporating it exhibit speed and size comparable to those of conventional non-rad-hard CMOS structure, relatively simple manufacturing, and excellent total-dose radiation hardness.
