  • Abstract
    We have investigated what effects randomly oriented and rotated poly-Si gate grains have on lateral carrier profiles in sub-50-nm MOSFETs by direct observations and electrical measurements. Since amorphous gates suppress random channeling penetration of pocket implants, we have increased effective mobility (40%), improved Vth roll-off characteristic (7 nm) and decreased Vth fluctuation (-26%)
