Abstract
A method of fabricating high-quality, substantially relaxed SiGe-on-insulator substrate is provided by implanting oxygen into a Si/SiGe multilayer heterostructure which comprises alternating Si and SiGe layers. Specifically, the high quality, relaxed SiGe-on-insulator is formed by implanting oxygen ions into a multilayer heterostructure which includes alternating layers of Si and SiGe. Following, the implanting step, the multilayer heterostructure containing implanted oxygen ions is annealed, i.e., heated, so as to form a buried oxide region predominately within one of the Si layers of the multilayer structure.
