    摘要: A sensor semiconductor device and a manufacturing method thereof are disclosed. The method includes: providing a light-permeable carrier board with a plurality of metallic circuits; electrically connecting the metallic circuits to a plurality of sensor chips through conductive bumps formed on the bond pads of the sensor chips, wherein the sensor chips have been previously subjected to thinning and chip probing; filling a first dielectric layer between the sensor chips to cover the metallic circuits and peripheries of the sensor chips; forming a second dielectric layer on the sensor chips and the first dielectric layer; forming grooves between the sensor chips for exposing the metallic circuits such that a plurality of conductive traces electrically connected to the metallic circuits can be formed on the second dielectric layer; and singulating the sensor chips to form a plurality of sensor semiconductor devices. The present invention overcomes the drawbacks of breakage of trace connection due to a sharp angle formed at joints, poor electrical connection and chip damage due to an alignment error in cutting from the back of the wafer, as well as an increased cost due to multiple sputtering processes for forming traces.
