摘要: A mask film of a material on which substantially no nitride semiconductor grows and having a plurality of openings in a stripe shape is formed on a main surface of a base substrate. Then, on the base substrate, a semiconductor layer of nitride is selectively grown through the mask film. Then, a laser beam is irradiated upon the interface between the semiconductor layer and the base substrate to separate the semiconductor layer from the base substrate, so that a nitride semiconductor substrate is formed from the semiconductor layer.

摘要: A semiconductor light source includes a light-emitting device 101 having a plurality of semiconductor layers made of nitride semiconductors, and a drive circuit 102 for driving the light-emitting device 101. The drive circuit 102 performs forward drive operation, in which a forward current is supplied to the light-emitting device to make the light-emitting device 101 emit light, and reverse drive operation, in which a reverse bias is applied to the light-emitting device. The magnitude of the reverse bias is limited by the value of a reverse current flowing through the light-emitting device.

摘要: A semiconductor laser (101) includes a first cladding layer (103), an active layer (105) and a second cladding layer (108). A window region (115) including fluorine, that is, an impurity element with higher electronegativity than nitrogen, is formed in the vicinity of a front end face (113) and a rear end face (114) of a laser resonator. The window region (115) is formed by exposing the front end face (113) and the rear end face (114) to carbon fluoride (CF4) plasma. The effective band gap of a portion of the active layer (105) disposed in the window region (115) is larger than the effective band gap of another portion of the active layer, and hence, it functions as an end face window structure for suppressing COD.

摘要: An InGaN-based light-emitting diode that emits light in blue, for example, is mounted on a support substrate as a semiconductor light-emitting element, and a transparent film is fixed to the support substrate so as to cover the semiconductor light-emitting element. An electrode pattern is formed on an upper surface of the transparent film, and the electrode pattern is electrically connected to terminal electrodes of the semiconductor light-emitting element through, for example, through-holes. The transparent film can contain a phosphor excited by light emitted from the semiconductor light-emitting element. It is not necessary to perform wire bonding for connecting the semiconductor light-emitting element to the electrode pattern and sealing with a sealant.

摘要: A first semiconductor film made of a nitride semiconductor is grown through epitaxial growth on a light transmitting substrate. A thermal decomposition layer is disposed in a space between the substrate and the first semiconductor film by irradiating laser light to the first semiconductor film from the back surface of the substrate. After a second semiconductor film made of a nitride semiconductor is grown through epitaxial growth while the first semiconductor film is placed on the substrate, the temperature of the substrate is lowered to room temperature. Then, by separating and removing the substrate from the first and second semiconductor films, it is possible to obtain a nitride semiconductor substrate having an area substantially as large as the area of the substrate.

摘要: A multilayer ceramic electronic component comprising an element body in which a dielectric layer and an internal electrode layer are stacked. The dielectric layer is constituted from a dielectric ceramic composition including; a compound having a perovskite structure expressed by a formula of ABO3 (A is at least one selected from Ba, Ca, and Sr; B is at least one selected from Ti, Zr, and Hf); an oxide of Mg; an oxide of rare earth elements including Sc and Y; and an oxide including Si. The dielectric ceramic composition comprises a plurality of dielectric particles and a grain boundary present in between the dielectric particles. In the grain boundary, when content ratios of Mg and Si are set to D(Mg) and D(Si) respectively, D(Mg) is 0.2 to 1.8 wt % in terms of MgO, and D(Si) is 0.4 to 8.0 wt % in terms of SiO2.
