    摘要: A method of semiconductor eutectic alloy metal (SEAM) technology for integration of heterogeneous materials and fabrication of compliant composite substrates takes advantage of eutectic properties of alloys. Sub1 and Sub2 are used to represent the two heterogeneous materials to be bonded or composed into a compliant composite substrate. For the purpose of fabricating compliant composite substrate, the first substrate material (Sub1) combines with the second substrate material (Sub2) to form a composite substrate that controls the stress in the epitaxial layers during cooling. The second substrate material (Sub2) controls the stress in the epitaxial layer grown thereon so that it is compressive during annealing. A joint metal (JM) with a melting point of Tm is chosen to offer variable joint stiffness at different temperatures. JM and Sub1 form a first eutectic alloy at a first eutectic temperature Teu1 while JM and Sub2 form a second eutectic alloy at a second eutectic temperature Teu2. Tm1 and Tm2 are the melting points of Sub1 and Sub2, respectively. The following condition should be met: Tm1, Tm2>Tm>Teu1, Teu2. After cleaning of Sub1 and Sub2, JM is deposited on the bonding sides of Sub1 and Sub2. After preliminary bonding by applying force to press the bonding surfaces together at room temperature, high temperature bonding is subsequently performed, during which the temperature is ramped up to a temperature equal to or higher than Tm. During cooling, JM solidifies first, after which two eutectic alloys solidify.

    摘要: A compliant substrate for the formation of semiconductor devices includes a crystalline base layer and a thin-film crystalline layer on and loosely bonded to the base layers. The thin-film layer has a high degree of lattice flexibility. A compliant substrate for formation of semiconductor devices may also include a crystalline base layer, and, on the base layer, a thin film layer having a lattice constant different from the lattice constant of the base layer. A method for formation of a compliant substrate for formation of semiconductor devices includes forming a thin film layer on a first substrate, bonding a first surface of the thin film layer to a surface of a second substrate having a lattice constant different from the lattice constant of the thin film layer either with or without twist bonding, and removing the first substrate to expose a second surface of the thin film layer.

    摘要: A prosthetic retina for implantation in an eye having a defective retina is formed from an array of nanowires having a predetermined spatial distribution, density, size and shape implanted in close proximity to the retina. An electrical conductor is formed at a first end of all nanowires in the array of nanowires and placed in contact with a bias source which biases the array. A plurality of electrodes is located on a second end of each of one nanowire or a bundle of nanowires in the array. Each nanowire produces a photocurrent at a corresponding electrode in response to detection of light impinging on the array of nanowires and the photocurrent stimulates one or more neurons adapted for visual perception. In the preferred embodiment, the predetermined spatial distribution mimics a distribution of rods and cones in a normal eye.

    摘要: A method for producing a stress-engineered substrate includes selecting first and second materials for forming the substrate. An epitaxial material for forming a heteroepitaxial layer is then selected. If the lattice constant of the heteroepitaxial layer (aepi) is greater than that (asub) of the immediate substrate layer the epitaxial layer is deposited on, then the epitaxial layer is kept under “compressive stress” (negative stress) at all temperatures of concern. On the other hand, if the lattice constant of the heteroepitaxial layer (aepi) is less than that (asub) of the immediate substrate layer the epitaxial layer is deposited on, then the epitaxial layer is kept under “tensile stress” (positive stress). The temperatures of concern range from the annealing temperature to the lowest temperature where dislocations are still mobile.
