The invention discloses a sensor package and a method for fabricating the same. The sensor package includes: a substrate with an opening; a sensor chip disposed in the opening and electrically connected to the substrate; an encapsulant filling spacing between the sensor chip and the opening so as to secure the sensor chip to the substrate; and a transparent cover attached to the substrate via an adhesive layer, wherein the adhesive layer covers the sensor chip and bonding wires and is formed with an opening for exposing sensor region of the sensor chip. Securing the sensor chip in the opening of the substrate reduces the height of the sensor package, and meanwhile the process cost is reduced by eliminating the need of formation of conductive bumps on the sensor chip or the transparent cover and eliminating the need of specially designed substrate.

A semiconductor package using copper wires and a wire bonding method for the same are proposed. The package includes a carrier having fingers and a chip mounted on the carrier. The method includes implanting stud bumps on the fingers of the carrier and electrically connecting the chip and the carrier by copper wires with one ends of the copper wires being bonded to bond pads of the chip and the other ends of the copper wires being bonded to the stud bumps on the carrier. The implanted stud bumps on the carrier improve bondability of the copper wires to the carrier and thus prevent stitch lift. With good bonding, residues of copper wires left behind after a bonding process have even tail ends and uniform tail length to enable fabrication of solder balls of uniform size, thereby eliminating a conventional step of implanting stud bumps on the bond pads of chips and preventing ball lift from occurring.

A sensor-type package and a fabrication method thereof are provided. A sensor-type chip is mounted on a substrate and is electrically connected to the substrate via bonding wires. A light-pervious body is attached to the sensor-type chip, and has one surface covered with a covering layer and another surface formed with an adhesive layer. An encapsulant encapsulates the light-pervious body. As an adhesive force between the covering layer and the encapsulant is greater than that between the covering layer and the light-pervious body, the covering layer and a portion of the encapsulant located on the covering layer can be concurrently removed, such that the light-pervious body is exposed and light can pass through the light-pervious body to be captured by the sensor-type chip. The above arrangement eliminates the need of using a dam structure as in the prior art and provides a compact sensor-type package with improved fabrication reliability.
