Abstract
A method is introduced for suppressing the penetration of boron for BF 2+-implanted pMOS devices with a stacked amorphous/ poly-Si (SAP) gate structure. It is shown that after inductive-coupling-nitrogen-plasma (ICNP) treatment, boron diffusion through the thin gale oxide is large ly suppressed. As shown from the charge-to-breakdown measurements, the ICNP process will improve the quality of pMOS devices, with Q(bd) thr ee times higher than for the control samples.
