Abstract :
This paper presents a low cost 0.25-μm technology with low standby power for 3.3 V applications. It is shown that as a single gate oxide n-type polysilicon gate technology is scaled, gate-induced drain-leakage (GIDL) in buried-channel PMOS becomes a serious limiting factor in achieving low standby power. The impact of technology choices such as spacer material, spacer width and poly reoxidation conditions on PMOS GIDL is discussed. A technology that successfully limits PMOS leakage is presented.
