  • Silicon sub-mount capable of single wire bonding and of providing ESD protection for light emitting devices
    Publication number: 20040089872
    Abstract: An apparatus consisting of a single wire bond silicon sub-mount used to make an LED device which also has built-in ESD protection in the sub-mount. The single wire bond silicon sub-mount uses a pass-through interconnection between the topside of the sub-mount and the underside so that the LED chip mounted thereon is electrically coupled through the sub-mount to the anode.
    Type: Application
