    摘要: The present disclosure provides a method for forming two device wafers starting from a single base substrate. The method includes first providing a structure which includes a base substrate with device layers located on, or within, a topmost surface and a bottommost surface of the base substrate. The base substrate may have double side polished surfaces. The structure including the device layers is spalled in a region within the base substrate that is between the device layers. The spalling provides a first device wafer including a portion of the base substrate and one of the device layers, and a second device wafer including another portion of the base substrate and the other of the device layer.

    摘要: A method of controlled layer transfer is provided. The method includes providing a stressor layer to a base substrate. The stressor layer has a stressor layer portion located atop an upper surface of the base substrate and a self-pinning stressor layer portion located adjacent each sidewall edge of the base substrate. A spalling inhibitor is then applied atop the stressor layer portion of the base substrate, and thereafter the self-pinning stressor layer portion of the stressor layer is decoupled from the stressor layer portion. A portion of the base substrate that is located beneath the stressor layer portion is then spalled from the original base substrate. The spalling includes displacing the spalling inhibitor from atop the stressor layer portion. After spalling, the stressor layer portion is removed from atop a spalled portion of the base substrate.

    摘要: A method for manufacturing a thin film direct bandgap semiconductor active solar cell device comprises providing a source substrate having a surface and disposing on the surface a stress layer having a stress layer surface area in contact with and bonded to the surface of the source substrate. Operatively associating a handle foil with the stress layer and applying force to the handle foil separates the stress layer from the source substrate, and leaves a portion of the source substrate on the stress layer surface substantially corresponding to the area in contact with the surface of the source substrate. The portion is less thick than the source layer. The stress layer thickness is below that which results in spontaneous spalling of the source substrate. The source substrate may comprise an inorganic single crystal or polycrystalline material such as Si, Ge, GaAs, SiC, sapphire, or GaN. In one embodiment the stress layer comprises a flexible material.

    摘要: Imparting a controlled amount of stress in an assembly comprising a semiconductor circuit on a substrate comprises depositing a tensile stressed metal film stressor layer onto the surface of the circuit. Establishing a fracture region below electrically active regions of the circuit, adhering a foil handle to the assembly and pulling it away from the assembly induces mechanical fracture in the fracture region below the electrically active regions. The mechanical fracture propagates parallel and laterally to the surface of the substrate and below the circuit to produce a thin flexible circuit on a residual substrate. The circuit is under compressive strain that is changed by modifying the stressor layer or residual substrate. Individualized circuits or a circuit may also be defined above the fracture by dividing the circuit into preselected regions with surrounding trenches before fracture. We harvest the circuit(s) by pulling the foil handle away from the assembly.
