  • Patent number: 6452091
    Abstract: The peeling of a thin-film single-crystal from a substrate is carried out so that the directions of straight lines on the single-crystal surface made by planes on which the single-crystal is apt to cleave are different from the front line direction of the peeled single-crystal. This single-crystal is used in a solar cell and a drive circuit member of an image display element. A method is provided which prevents a decrease in quality and yield of a single crystal layer when it is peeled from a substrate. A flexible solar cell module having a thin film single-crystal layer is made so that its flexing direction is different from the single-crystal's cleaving direction. Thus, a thin-film single-crystal solar cell module having excellent durability and reliability due to a lack of defect or cracking during production and use, and a method for producing the same, is provided.

  • Patent number: 6440765
    Abstract: A method for fabricating an infrared-emitting light-emitting diode in which a layer sequence is applied onto a semiconductor substrate, preferably composed of GaAs. The layer sequence has, proceeding from the semiconductor substrate, a first AlGaAs cover layer, a GaAs and/or AlGaAs containing active layer and a second AlGaAs cover layer. In which case, the first AlGaAs cover layer and the active layer are fabricated by a metal organic vapor phase epitaxy (MOVPE) method and the second AlGaAs cover layer is fabricated by a liquid phase epitaxy (LPE) method. Furthermore, an electrically conductive coupling-out layer having a thickness of at least about 10 &mgr;m is deposited on the second AlGaAs cover layer by the LPE method. The coupling-out layer is optically transparent in the infrared spectral region.

  • Publication number: 20020106865
    Abstract: A method of forming a shallow trench isolation (STI) structure. A pad oxide layer and a cap layer are sequentially formed over a substrate. The pad oxide layer, the cap layer and the substrate are patterned to form a trench. Oxide material is deposited into the trench to form a first oxide layer. The cap layer is removed to expose a portion of the first oxide layer. The pad oxide layer is removed. A selective liquid phase deposition is conducted to form a second oxide layer around the exposed first oxide layer.

  • Patent number: 6406982
    Abstract: A trench is formed in a semiconductor substrate through a mask composed of a silicon oxide film formed on the semiconductor substrate. Then, an edge portion at an opening portion of the mask is etched so that an opening width thereof is wider than that of the trench. After that, an inner surface of the trench is smoothed by thermal treatment around at 1000° C. in non-oxidizing or non-nitriding atmosphere under low pressure. Then, the trench is filled with an epitaxial film. After that, the epitaxial film is polished, whereby a semiconductor substrate for forming a semiconductor device is obtained.

  • Patent number: 6306736
    Abstract: A process for the formation of shaped Group III-V semiconductor nanocrystals comprises contacting the semiconductor nanocrystal precursors with a liquid media comprising a binary mixture of phosphorus-containing organic surfactants capable of promoting the growth of either spherical semiconductor nanocrystals or rod-like semiconductor nanocrystals, whereby the shape of the semiconductor nanocrystals formed in said binary mixture of surfactants is controlled by adjusting the ratio of the surfactants in the binary mixture.

  • Patent number: 6306739
    Abstract: In this invention, one or more metal-containing sources and one or more ammonium halides are heated such that they evaporate into a vacuum environment (except that, in MOMBE, a beam of the organometallic source compound may be created by other means) and made to impinge on a substrate. The materials interact on the substrate to form a film of the desired nitride compound or alloy; the substrate usually will be heated to promote chemical reaction and good film properties such as high crystallinity. Other sources—to provide dopant impurities like silicon or magnesium, for example—would be part of a deposition system envisioned in this invention. Multiple film layers, including quantum wells and superlattices, may be formed using this method, in addition to a single film.

  • Patent number: 6306734
    Abstract: A method for growing of oriented whisker arrays on a single-crystalline substrate consists in vapor-phase transport of the material to be crystallized form a solid-state source body of the same composition as the whiskers to the substrate coated with liquid-phase particles that serve as nucleation/catalyzing centers for the whisker growth. The source body has a plane surface that is faced to the substrate and parallel to it so that a vectorly-uniform temperature field, whose gradient is perpendicular to both the substrate and the source, is created. The vectorly-uniform temperature field is realized by an apparatus with high-frequency heating of specially designed bodies that are arranged in a special position in respect to the high-frequency inductor. Laser and/or lamp heat sources can be also used either separately or in combinations with the high-frequency heater. In the apparatus, the material source is heated, while the substrate takes heat from the material source.
