A linear integrated optocoupler and method for forming the same.

摘要

A linear optocoupler (71) having a light emitting diode (28) and a detector diode (29) formed on a common semiconductor substrate (33). Light emitted by the light emitting diode (28) is transmissive to semiconductor substrate (33). A layer of light reflective material (34) is formed on a side opposite from which the light emitting diode (28) and the detector diode (29) on the semiconductor substrate (33). A portion of light emitted by the light emitting diode (28) transmits through the semiconductor substrate (33) to be reflected by the layer of light reflective material (34). The reflected light transmits through the semiconductor substrate (33) to be received by the detector diode (29). A photo detector diode (61) and the semiconductor substrate (33) including the light emitting diode (28) and the detector diode (29) are mounted on a lead frame (51) co-planar to one another. A light flux coupling media (76) couples light from the light emitting diode (28) to the photo detector diode (29).
