Patent ID: 8412006

Claim:
An optocoupler comprising: a substrate; a plurality of conductive traces on the substrate; a conductive pad located on the substrate; an optical transmitter die, the optical transmitter die operable to emit light; a first conductive trace of the plurality of conductive traces configured to provide power to the optical transmitter die from a first power supply; an optical receiver die, the optical receiver die operable to receive light generated by the optical transmitter die; and a second conductive trace of the plurality of conductive traces configured to provide power to the optical receiver die from a second power supply, the first conductive trace being electrically isolated from the second conductive trace; wherein one of the optical transmitter and receiver dies is attached directly to the conductive pad, the other one of the optical transmitter and receiver dies is attached to the conductive pad through three layers of materials comprising an isolation layer sandwiched between two attachment layers.
