Abstract :
Trenched Schottky-barrier (TSB) contact PMOS devices for use in latchup-free CMOS are examined in detail, and compared to Schottky-contact PMOS. Measurements and simulations show that the TSB structure has significant advantages in gain and current leakage over the Schottky-contact structure, CMOS using TSB PMOS may be made unconditionally free of Iatchup. The tradeoffs involving PMOS source-drain implant dose are made explicit and correlated to Iatchup measurements.
