Patent ID: 7482666

Claim:
An optoisolator device, the device comprising: a die attachment device having a planar surface; a first circuit die having a substantially quadrangular shape with first and second planar surfaces and a first side surface, the first circuit die having a receiver circuit formed substantially on the first planar surface of the first circuit die and a first photodiode formed adjacent to the first side surface of the circuit die and electrically coupled to the receiver circuit, where the second planar surface of the first circuit die is attached to the planar surface of the die attachment device; a second circuit die having a transmitter circuit that includes a first light emitting diode, where the second circuit die is attached to the die attachment device in a position substantially adjacent to the first side surface of the first circuit die so that there is an optically unobstructed path from the first light emitting diode to the first photodiode; and a clear plastic layer formed on the planar surface of the die attachment device over the first and second circuit dies.
