Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials.

Abstract: High quality cubic boron nitride layers can be grown overlying monocrystalline substrates (102) such as large silicon wafers by forming a compliant substrate for growing the nitride layer. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer (104) on a silicon wafer (102). The accommodating buffer layer (104) is a layer of monocrystalline oxide spaced apart from the silicon wafer (102) by an amorphous interface layer of silicon oxide (108). The amorphous interface layer (108) dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer (104).

One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. A monocrystalline graded layer, in which the lattice constant varies with the thickness of the layer, is then formed over the accommodating buffer layer, such that a lattice constant of the top of the graded layer substantially matches the lattice constant of a subsequently grown monocrystalline film.

Abstract: High quality epitaxial layers of oxide can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous intermediate layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous intermediate layer. Waveguides may be formed of high quality monocrystalline material atop the monocrystalline buffer layer. The waveguides can suitably be formed to modulate the wave. Monolithic integration of oxide based electro-optic devices with III-V based photonics and Si circuitry is fully realized.
