    摘要: Methods and structures for monolithically integrating monocrystalline silicon and monocrystalline non-silicon materials and devices are provided. In one structure, a monolithically integrated semiconductor device structure comprises a silicon substrate and a first monocrystalline semiconductor layer disposed over the silicon substrate, wherein the first monocrystalline semiconductor layer has a lattice constant different from a lattice constant of relaxed silicon. The structure further includes an insulating layer disposed over the first monocrystalline semiconductor layer in a first region and a monocrystalline silicon layer disposed over the insulating layer in the first region. The structure includes at least one silicon-based photodetector comprising an active region including at least a portion of the monocrystalline silicon layer. The structure also includes a second monocrystalline semiconductor layer disposed over at least a portion of the first monocrystalline semiconductor layer in a second region and absent from the first region, wherein the second monocrystalline semiconductor layer has a lattice constant different from the lattice constant of relaxed silicon.

    摘要: Semiconductor-based devices, and methods for making the devices, involve a first device that includes a buried channel layer, a dielectric layer, and a compositionally graded spacer layer. The spacer layer includes a first material and a second material, and is located between the buried channel layer and the dielectric layer. A second device includes a buried channel layer, a relaxed surface layer, and a spacer layer located between the buried channel layer and the relaxed surface layer. The spacer layer has a composition that is different from a composition of the relaxed layer. The spacer layer and the relaxed surface layer each have bandgap offsets relative to the buried channel layer to reduce a parasitic channel conduction. A substrate for fabrication of devices, and methods for making the substrate, involves a substrate that includes a first layer, such as a silicon wafer, a substantially uniform second layer, and a graded-composition third layer.
