2443 results about "Wire bonding" patented technology

Wire bonding is the method of making interconnections (ATJ) between an integrated circuit (IC) or other semiconductor device and its packaging during semiconductor device fabrication. Although less common, wire bonding can be used to connect an IC to other electronics or to connect from one printed circuit board (PCB) to another. Wire bonding is generally considered the most cost-effective and flexible interconnect technology and is used to assemble the vast majority of semiconductor packages. Wire bonding can be used at frequencies above 100 GHz.

Light-emitting diode device and method of manufacturing the same

A light-emitting diode device, such as a blue, green, blue-green light-emitting diode, with a one-wire-bonding characteristic and the method of manufacturing the same have been disclosed. The light-emitting diode device has a GaN-based semiconductor laminated structure formed on an insulating substrate. The GaN-based semiconductor laminated structure includes an n-type layer on its bottom side, a p-type layer on its top side, and an active layer, for generating light, sandwiched between the n-type and p-type layers. An annular isolation portion such as a trench or a high resistivity portion formed by ion implantation is formed in the GaN-based semiconductor laminated structure to separate the p-type layer into a central p-type layer and a peripheral p-type layer and to separate the active layer into a central active layer and a peripheral active layer. A p-type electrode is formed on the central p-type layer without electrically connecting to the peripheral p-type layer. A conductive layer is coated to cover the sidewalls and the bottom surface of the insulating substrate and to ohmically contact with the n-type layer. Preferably, an adhesion layer is sandwiched between the sidewalls and the bottom surface of the insulating substrate and the conductive layer to enhance the adhesive property. According to the present invention, the conductive layer may be formed as a mirror-like reflector or a light-transmissive layer.
