Patent ID: 7855426

Claim:
An optical sensor assemblage, comprising: a sensor chip assemblage including an optically transparent irradiation region, a mounting region surrounding the optically transparent irradiation region, and a wire-bond region; an optically isolating mounting frame including a chip receiving region and a plurality of connector elements; and an optically isolating packaging device; wherein: the sensor chip assemblage is joined in the mounting region to the chip receiving region, and in the wire-bond region to at least one of the connector elements, the chip receiving region includes a window disposed in such a way that at least a portion of the optically transparent irradiation region is not covered by the chip receiving region, the optically isolating packaging device surrounds the sensor chip assemblage and the optically isolating mounting frame in such a way that optical radiation can enter the sensor chip assemblage substantially only through the window the sensor chip assemblage includes a first chip and a second chip, the first chip includes a first surface and a second surface oppositely located to the first surface, the second chip includes a third surface and a fourth surface oppositely located to the third surface, the first chip and the second chip are joined via the first surface and the third surface, the first chip and the second chip enclose a cavity in which a sensor is disposed, the first chip includes on the first surface the wire-bond region, the wire-bond region protrudes laterally beyond the second chip, and at least another of the connector elements is bonded onto the wire-bond region with a bonding pad at an end of a conductor path.
