Abstract: A vertical GaN-based LED is made by growing an epitaxial LED structure on a silicon wafer. A silver layer is added and annealed to withstand >450° C. temperatures. A barrier layer (e.g., Ni/Ti) is provided that is effective for five minutes at >450° C. at preventing bond metal from diffusing into the silver. The resulting device wafer structure is then wafer bonded to a carrier wafer structure using a high temperature bond metal (e.g., AlGe) that melts at >380° C. After wafer bonding, the silicon is removed, gold-free electrodes (e.g., Al) are added, and the structure is singulated. High temperature solder (e.g., ZnAl) that is compatible with the electrode metal is used for die attach. Die attach occurs at >380° C. for ten seconds without melting the bond metal or otherwise damaging the device. The entire LED contains no gold, and consequently is manufacturable in a high-volume gold-free semiconductor fabrication facility.

Abstract: An LED device includes a strip-shaped electrode, a strip-shaped current blocking structure and a plurality of distributed current blocking structures. The current blocking structures are formed of an insulating material such as silicon dioxide. The strip-shaped current blocking structure is located directly underneath the strip-shaped electrode. The plurality of current blocking structures may be disc shaped portions disposed in rows adjacent the strip-shaped current blocking structure. Distribution of the current blocking structures is such that current is prevented from concentrating in regions immediately adjacent the electrode, thereby facilitating uniform current flow into the active layer and facilitating uniform light generation in areas not underneath the electrode. In another aspect, current blocking structures are created by damaging regions of a p-GaN layer to form resistive regions.

Abstract: An electronic device includes a body with a slide member, a supporter connected to the slide member to support the body placed on a plane, and a fastener combining the supporter and the slide member to make the supporter locate at a first position of the slide member. When the body is applied a force, the supporter moves along the slide rod to locate at a second position to adjust an angle between the body and the plane.

Abstract: The present invention discloses a vehicle emission monitoring device and a method thereof. The method of the present invention comprises steps: obtaining an OBS instantaneous fuel consumption and a carbon dioxide emission from an on-board emission measurement system (OBS); working out an OBS fuel consumption-carbon dioxide emission relationship with a statistical method or a regression method; obtaining an OBD instantaneous fuel consumption from an on-board diagnostic (OBD) system; establishing an OBS-OBD fuel consumption relationship; and converting the OBD instantaneous fuel consumption into an carbon dioxide emission according to the OBS-OBD fuel consumption relationship and the OBS fuel consumption-carbon dioxide emission relationship.

Abstract: A light source and method for making the same are disclosed. The light source includes a conducting substrate, and a light emitting structure that is divided into segments. The light emitting structure includes a first layer of semiconductor material of a first conductivity type deposited on the substrate, an active layer overlying the first layer, and a second layer of semiconductor material of an opposite conductivity type from the first conductivity type overlying the active layer. A barrier divides the light emitting structure into first and second segments that are electrically isolated from one another. A serial connection electrode connects the first layer in the first segment to the second layer in the second segment. A power contact is electrically connected to the second layer in the first segment, and a second power contact electrically connected to the first layer in the second segment.

Abstract: An article holder includes a base, a pair of opposing side walls spaced apart and diverging away from each other moving forward from the rear of the base, and lower and upper rear walls spaced from each other and substantially co-planar. The base, side walls and rear walls define a storage region for holding articles in a vertical orientation, and provide that one holder may be nested within another like holder.
