Abstract
Summary form only given. The authors discuss the use of an MBE grown Si0.7Ge0.3 strained layer as an etch stop, and the successful fabrication of bond and etch-back silicon on insulator with an undoped 200-nm silicon layer using this technology. Full integrity of the etch stop was maintained following oxidation and bonding of the prime wafer. Defects generated in the strained etch stop region during thermal treatments did not propagate into the active silicon device region
