Abstract: A gallium nitride (GaN) power device includes a GaN substrate structure having a first surface and a second surface, a metallic layer coupled to the second surface of the GaN substrate structure, and an active region including an array of vertical fin-based field effect transistors (FinFETs) coupled to the GaN substrate structure. The GaN power device also includes an edge termination structure circumscribing the active region and a seal ring structure circumscribing the edge termination structure and comprising a seal ring metal pad operable to conduct charge from the edge termination structure to the metallic layer.

Abstract: Interlacing equipment may be used to form fabric and to create a gap in the fabric. The fabric may include one or more conductive strands. An insertion tool may be used to align an electrical component with the conductive strands during interlacing operations. A soldering tool may be used to remove insulation from the conductive strands to expose conductive segments on the conductive strands. The soldering tool may be used to solder the conductive segments to the electrical component. The solder connections may be located in grooves in the electrical component. An encapsulation tool may dispense encapsulation material in the grooves to encapsulate the solder connections. After the electrical component is electrically connected to the conductive strands, the insertion tool may position and release the electrical component in the gap. A component retention tool may temporarily be used to retain the electrical component in the gap as interlacing operations continue.

Abstract: The hydrocarbon light-off time in engine exhaust is reduced by employing a hydrogen oxidation catalyst, a CO oxidation catalyst of light-off temperature for CO and/or hydrogen below ambient temperature, and sufficient oxygen and sufficient CO and/or hydrogen in the exhaust that the exothermic reaction of the oxygen with the CO and/or hydrogen over the CO oxidation catalyst generates enough heat to raise the temperature of the CO oxidation catalyst to at least the light-off temperature of the hydrocarbon oxidation catalyst.

Abstract: Substantial improvements in the control of pollutants from internal combustion engines may be obtained by pre-drying a catalyst/hydrocarbon trap system and preferably incorporating a water trap in a catalyst/hydrocarbon trap system. A pre-drying system dries the water trap, HC trap and catalyst, eg upon engine switch-off.
