  • Abstract
    A new design approach featured by potential profile engineering is proposed for deep sub-half micron buried channel pMOSFETs by placing n regions within the LDD depletion layers. The newly designed n regions are effective for suppressing drain induced barrier lowering (DIBL) of buried channel pMOSFETs, without any degradation in Vt controllability. Simulation results suggest the potential profile engineering is useful for designing 0.25 mu m buried channel pMOSFETs with high driving capability and good Vt controllability.<>
