Abstract
A semiconductor device and processing technique is provided for monolithic integration of a single crystal compound element semiconductor on a ceramic substrate. A high resistivity semi-insulating buffer layer is epitaxially grown on the ceramic substrate and has an elastically transitional lattice constant matching at its lower surface the lattice constant of the ceramic substrate, and matching at its upper surface the lattice constant of the semiconductor layer.
