Abstract: A METHOD FOR FORMING STRAINED SI OR SIGE ON RELAXED SIGE ON INSULATOR (SGOJ) IS DESCRIBED INCORPORATING GROWING EPITAXIAL SI1GE LAYERS ON A SEMICONDUCTOR SUBSTRATE, IMPLANTING HYDROGEN INTO A SELECTED SI1..GE LAYER TO FORM A HYDROGENERICH DEFECTIVE LAYER, SMOOTHING SURFACES BY CHEMO-MECHANICAL POLISHING, BONDING TWO SUBSTRATES TOGETHER VIA THEXMAL TREATMENTS AND SEPARATING TWO SUBSTRATES AT THE HYDROGEN-RICH DEFECTIVE LAYER. THE SEPARATED SUBSTRATES MAY HAVE ITS UPPER SURFACE SMOOTHED BY CMI’ FOR EPITAXIAL DEPOSITION OF RELAXED SI,GE,,, AND STRAINED SI1GE DEPENDING UPON COMPOSITION, STRAINED SI, STRAINED SIC, STRAINED GE, STRAINED GEC, AND STRAINED SI3GEC.
