  • Publication number: 20100148120
    Abstract: A light-emitting apparatus composed of a light source that emits primary light and a phosphor that absorbs the primary light and emits secondary light offers high brightness, low power consumption, and a long lifetime while minimizing adverse effects on the environment. The phosphor is formed of a III-V group semiconductor in the form of fine-particle crystals each having a volume of 2 800 nm3 or less. The light emitted from the fine-particle crystals depends on their volume, and therefore giving the fine-particle crystals a predetermined volume distribution makes it possible to adjust the wavelength range of the secondary light.

  • Patent number: 7327770
    Abstract: To prevent deterioration induced by wire bonding in a laser device incorporating a semiconductor laser element having a nitride semiconductor laid on top of a nitride semiconductor substrate, the position at which a wire (301) is bonded to an electrode (113) formed on the top surface of a semiconductor layered structure is located off the area right above a dislocation (crystal defect)-concentrated region (X) of the substrate. Concentration of dislocations in the substrate spreads to the layered structure, producing a dislocation-concentrated region in the part of the layered structure located right above the dislocation-concentrated region of the substrate. If a wire is bonded above this region, the pressure applied when the wire is bonded causes the metal of which the electrode is made to diffuse along the concentrated dislocations, lowering the quality of the layered structure and thus resulting in deterioration of the element.

  • Patent number: 7326580
    Abstract: Aspects of the invention can provide a method of effectively observing the photodecomposition process of a monolayer in real time. The invention can provide a method of observing the decomposition process of a monolayer when the monolayer is irradiated with UV rays, where the structure of the constituent molecule of the monolayer in an ultrahigh vacuum atmosphere and an oxygen-containing atmosphere respectively can be measured by a molecular structure measuring device during the UV irradiation. The invention can also provide a method of controlling the degree of surface decomposition of the monolayer that controls the ozone concentration accompanying the UV irradiation based on observation results obtained by using the observation method. The invention can further provide a method of patterning the monolayer that employs the control method.
