  • Abstract
    In this work the effect of doping concentration on the piezoresistive and electrical properties of poly-SiGe deposited at temperatures compatible with MEMS integration on top of CMOS are evaluated for the first time. With proper tuning of the boron content, a gauge factor around 14 and a TCR close to 0 are achievable. These results prove the potential of using poly-SiGe as a sensing layer for MEMS-above-CMOS applications.
