Abstract
A sensor package structure is provided. The sensor package structure includes a substrate, a sensor chip disposed on the substrate, a plurality of electrical connection members electrically connecting the sensor chip to the substrate, a supporting adhesive layer formed on the sensor chip, and a light-permeable sheet disposed on the supporting adhesive layer. Each of the electrical connection members includes a head solder disposed on a connecting pad of the sensor chip, a wire having a first end and a second end, and a tail solder. The first end of the wire extends from the head solder so as to connect the second end onto a soldering pad of the substrate, and the wire has a first bending portion arranged adjacent to the head solder. The head solder and the first bending portion of each of the electrical connection members are embedded in the supporting adhesive layer.
