  • Publication number: 20240072210
    Abstract: A micro light emitting diode structure including an epitaxial structure, a first insulating layer and a second insulating layer is provided. The epitaxial structure includes a first type semiconductor layer, a light emitting layer and a second type semiconductor layer. The first type semiconductor layer, the light emitting layer and a first portion of the second type semiconductor layer form a mesa. A second portion of the second type semiconductor layer is recessed relative the mesa to form a mesa surface. The first insulating layer covers from a top surface of the mesa to the mesa surface along a first side surface of the mesa, and exposes the second side surface. The second insulating layer directly covers a second side surface of the second portion, wherein a thickness ratio of the first insulating layer to the second insulating layer is between 10 and 50.

  • Publication number: 20060214330
    Abstract: An imprint lithographic method for making a polymeric structure comprising the steps of: (a) providing a mold having a shape forming a mold pattern; (b) providing a substrate having a higher surface energy relative to said mold; (c) providing a polymer film on said mold, said polymer film having a selected thickness, wherein the selected thickness of the polymer film on the mold pattern is capable of forming at least one frangible region in the polymer film having a thickness that is less than the remainder of the polymer film; (d) pressing the mold and the substrate relatively toward each other to form said frangible region; and (e) releasing at least one of said mold and said substrate from the other, wherein after said releasing, said frangible region remains substantially attached to said mold while the remainder of said polymer film forms the polymeric structure attached to said substrate.

  • Patent number: 6982215
    Abstract: A method for using ion implantation to implant phosphorous or arsenic impurities into shallow source/drain regions or into polysilicon electrodes used in devices having shallow source/drain electrodes. A phosphorous source having an abundance of P2+ ions is used in an ion beam system adjusted to select P2+ ions. Since each ion contains two phosphorous atoms the ion beam requires twice the beam energy and half the beam density. This provides good wafer throughput and improved source life. An arsenic source having an abundance of As2+ ions can be substituted for the solid phosphorous source resulting in a beam of As2+ ions.

  • Publication number: 20050258570
    Abstract: The present invention is directed to micro- and nano-scale imprinting methods and the use of such methods to fabricate supported and/or free-standing 3-D micro- and/or nano-structures of polymeric, ceramic, and/or metallic materials. In some embodiments, a duo-mold approach is employed in the fabrication of these structures. In such methods, surface treatments are employed to impart differential surface energies to different molds and/or different parts of the mold(s). Such surface treatments permit the formation of three-dimensional (3-D) structures through imprinting and the transfer of such structures to a substrate. In some or other embodiments, such surface treatments and variation in glass transition temperature of the polymers used can facilitate separation of the 3-D structures from the molds to form free-standing micro- and/or nano-structures individually and/or in a film.
