摘要： An (Al, Ga, In)N light emitting device, such as a light emitting diode (LED), in which high light generation efficiency is realized by fabricating the device on non-polar or semi-polar III-Nitride crystal geometries. Because non-polar and semi-polar emitting devices have significantly lower piezoelectric effects than c-plane emitting devices, higher efficiency emitting devices at higher current densities can be realized.

摘要： A gallium nitride (GaN) based light emitting diode (LED), wherein light is extracted through a nitrogen face (N-face) of the LED and a surface of the N-face is roughened into one or more hexagonal shaped cones. The roughened surface reduces light reflections occurring repeatedly inside the LED, and thus extracts more light out of the LED. The surface of the N-face is roughened by an anisotropic etching, which may comprise a dry etching or a photo-enhanced chemical (PEC) etching.

摘要： A method for fabricating a III-nitride based semiconductor device, including (a) growing one or more buffer layers on or above a semi-polar or non-polar GaN substrate, wherein the buffer layers are semi-polar or non-polar III-nitride buffer layers; and (b) doping the buffer layers so that a number of crystal defects in III-nitride device layers formed on or above the doped buffer layers is not higher than a number of crystal defects in III-nitride device layers formed on or above one or more undoped buffer layers. The doping can reduce or prevent formation of misfit dislocation lines and additional threading dislocations. The thickness and/or composition of the buffer layers can be such that the buffer layers have a thickness near or greater than their critical thickness for relaxation. In addition, one or more (AlInGaN) or III-nitride device layers can be formed on or above the buffer layers.

摘要： A key switch preferably used for a keyboard as an input device in electronic equipment. The key switch includes a base section; a key top disposed above the base section; a pair of link members interlocked to each other to support and direct the key top in a vertical direction relative to the base section; a switch member including a contact section capable of opening and closing in response to a vertical movement of the key top; and a biasing member capable of applying an elastic biasing force in a vertically upward direction to the key top. The key switch further includes a protection member disposed and inserted between the base section and the key top at a position where the protection member surrounds the pair of link members, the contact section and the biasing member. The protection member is elastically deformed to follow the vertical movement of the key top, and protects the pair of link members, the contact section and the biasing member from penetration of foreign matter.
