    摘要: An improved method and apparatus for crystallizing amorphous or polycrystalline material is disclosed. In this invention, a material which is to be crystallized is formed on a substrate and single crystalline seed material is disposed in contact and/or adjacent to or with at least a portion of the material which is to be crystallized. A layer of material which serves as a "wetting agent" is then formed over the material to be crystallized. The structure thus formed is subjected to a heat treatment which melts the material being crystallized and when the material solidifies its crystalline structure is substantially epitaxial based on the seed material. The "wetting agent" layer serves to prevent deleterious balling up of the material during crystallization.

    摘要: An improved method and apparatus for optimizing the electrical properties while crystallizing material is disclosed. In this invention, a material which is to be crystallized is formed on a substrate and subjected to a heat treatment to intentionally induce thermal stress while crystallizing the material. The heat treatment melts the material being crystallized and when the material solidifies, a built-in stress is retained which, in the case of n-doped Si on fused silica results in a tensile stress which produces an electron mobility in the film of 870 cm.sup.2 /volt-sec as compared to similarly fashioned unstressed n-doped Si on SiO.sub.2 coated Si which has an electron mobility of 500 cm.sup.2 /volt-sec.

    摘要: An active matrix color sequential liquid crystal display has an active matrix circuit, a counterelectrode panel and an interposed layer of liquid crystal. The active matrix circuit has an array of transistor circuits formed in a first plane. Each transistor circuit is connected to a pixel electrode in an array of pixel electrodes having a small area. The counterelectrode panel extends in a second plane that is parallel to the first plane, such that the counterelectrode panel receives an applied voltage. The liquid crystal layer is interposed in a cavity between the two planes. In a preferred embodiment, an oxide layer extends over the pixel electrode array. The oxide can have a first thickness in a peripheral region around the array of the pixel electrodes and a thinner second thickness in a pixel electrode region extending over the array of pixel electrodes.

    摘要: An improved electrode for a p-type gallium nitride based semiconductor material is disclosed that includes a layer of an oxidized metal and a first and a second layer of a metallic material. The electrode is formed by depositing three or more metallic layers over the p-type semiconductor layer such that at least one metallic layer is in contact with the p-type semiconductor layer. At least two of the metallic layers are then subjected to an annealing treatment in the presence of oxygen to oxidize at least one of the metallic layers to form a metal oxide. The electrodes provide good ohmic contacts to p-type gallium nitride-based semiconductor materials and, thus, lower the operating voltage of gallium nitride-based semiconductor devices.

    摘要: A bonding pad for an electrode is in contact with p-type gallium nitride-based semiconductor material that includes aluminum. The bonding pad may also includes one or more metals selected from the group consisting of palladium, platinum, nickel and gold. The bonding pad can be used to attach a bonding wire to the p-electrode in a semiconductor device, such as a light-emitting diode or a laser diode without causing degradation of the light-transmission and ohmic properties of the electrode. The bonding pad may be formed of substantially the same material as an electrode in making an ohmic contact with n-type gallium nitride-based semiconductor material (n-electrode). This allows the bonding pad and the n-electrode to be formed simultaneously when manufacturing a gallium nitride-based light-emitting device which substantially reduces the cost to manufacture the device.
