Abstract :
It has been shown that the PIII/PLAD poly-Si gate doping process offers unique advantages over conventional beam line systems, including system simplification, lower cost, higher throughput, and device performance equivalence or improvement. PMOS devices fabricated by a B 2H6/H2 PIII/PLAD process on P+ poly-gate doping are intensively evaluated in this paper. In addition to higher throughput, PMOS devices fabricated by a PLAD process showed an equivalent electrical performance to those fabricated by conventional beam line ion implantation, including similar poly-Si gate resistance and depletion, threshold and sub-threshold characteristics, drive current, and gate-oxide integrity
