Abstract: Semiconductor print engine structures (304) are formed by growing high quality epitaxial layers (26) of monocrystalline materials overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. The compliant substrate includes an accommodating buffer layer (24) including a layer of monocrystalline oxide spaced apart from a silicon wafer (22) by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer (28) dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer (24).

Abstract: High quality monocrystalline metal oxide layers are grown on a monocrystalline substrate such as a silicon wafer. The monocrystalline metal oxide is grown on the silicon substrate at a temperature low enough to prevent deleterious and simultaneous oxidation of the silicon substrate. After a layer of 1-3 monolayers of the monocrystalline oxide is grown, the growth is stopped and the crystal quality of that layer is improved by a higher temperature anneal. Following the anneal, the thickness of the layer can be increased by restarting the low temperature growth. An amorphous silicon oxide layer can be grown at the interface between the monocrystalline metal oxide layer and the silicon substrate after the thickness of the monocrystalline oxide reaches a few monolayers.

Abstract: Phased array components utilizing two or more different types of semiconductor in one monolithic device are provided. High quality epitaxil layers of monocrystalline materials (26) can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer (24) comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface 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 interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxil growth of single crystal silicon onto single crystal oxidematerials.
