  • Publication number: 20060270190
    Abstract: A method for transferring a monocrystalline, thin layer from a first substrate onto a second substrate involves deposition of a doped semiconductor layer on a substrate and epitaxial growth of a thin, monocrystalline, semiconductor layer on the doped layer. After bonding the thin epitaxial monocrystalline semiconductor layer to a second substrate, hydrogen is introduced into the doped layer, and the thin layer is cleaved and transferred to the second substrate, with the cleaving controlled to happen at the doped layer.

  • Publication number: 20060234474
    Abstract: A method for transferring a monocrystalline, thin layer from a first substrate onto a second substrate involves epitaxial growth of a sandwich structure with a strained epitaxial layer buried below a monocrystalline thin layer, and lift-off and transfer of the monocrystalline thin layer with the cleaving controlled to happen within the buried strained layer in conjunction with the introduction of hydrogen.

  • Publication number: 20050140283
    Abstract: A multilayer structure to form an active matrix display with single crystalline Si TFTs over a transmissive substrate. A light-emitting device is integrated with a single-crystalline Si layer over the light-transmitting substrate. The light generated by the light-emitting device is emitted from the substrate.
