Abstract
Single crystal layers of Group IV semiconductor materials, such as silicon, are grown on insulating substrates. The fabrication of this structure is achieved by forming on a single crystal substrate a layer of an insulating material, such as a silicon oxide. A small via hole is produced in the insulating layer to leave a portion of the underlying substrate uncovered. A precursor material is deposited on the insulating layer so that it covers at least a portion of the insulating layer and also contacts the substrate at the via hole. The precursor layer is then formed into a single crystal by inducing growth on the substrate at the via hole and propagating this growth through the precursor layer.
