Improving device performance and variability for 28nm and beyond low power SoC technology using advanced implant solutions

Advanced junction scaling with device performance gain, leakage reduction and reduced threshold voltage (Vth) variation are critical for CMOS 28nm node and future scaling. In this paper, implant induced defect engineering for higher drive current with reduced SRAM defectivity, advanced junction formation and Vth mismatch (Vtmin) on a state-of-the-art 28nm logic flow are demonstrated and discussed.
