Apparatus and method for attaching integrated circuit structures and devices utilizing the formation of a compliant substrate to a circuit board
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. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a 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. Once the integrated circuit having the above layers is fabricated, it is attached to a circuit board. The integrated circuit has an insulative layer formed on a side edge and electrical signals are passed from the integrated circuit to an input/output pad, through a conductive path and then to another input/output pad that is located on the circuit board.
