  • Masked-gate MOS S/D implantation
    Patent number: 5700729
    Abstract: The problem of how to prevent trapping charge during high energy ion implantation, as part of a PLDD, NLDD, PS/D, and NS/D manufacturing process, has been solved through use of a protective cap of photoresist which is applied to the gate prior to the high energy ion implantation. Said protective cap is readily removed after ion implantation.
