Patent ID: 7498191

Claim:
A method of making a semiconductor-on-diamond substrate, comprising: depositing a base layer onto a lattice-orienting Si substrate such that the base layer lattice is substantially oriented by the Si substrate, said base layer including a member selected from the group consisting of AlP, BAs, GaN, InN, and combinations thereof; depositing a semiconductor layer onto the base layer such that the semiconductor layer lattice is substantially oriented with respect to the base layer lattice; disposing a layer of diamond onto the semiconductor layer; removing the lattice-orienting Si substrate and the base layer from the semiconductor layers, wherein the base layer is deposited onto a (100) face of the lattice-orienting Si substrate such that the base layer is deposited as a cubic base layer and the semiconductor layer is deposited onto a (100) face of the cubic base layer such that the semiconductor layer is deposited as a cubic semiconductor layer.
