摘要： A sensor semiconductor device and a method for fabricating the same are provided. At least one sensor chip is mounted and electrically connected to a lead frame. A first and a second encapsulation molding processes are sequentially performed to form a transparent encapsulant for encapsulating the sensor chip and a part of the lead frame and to form a light-impervious encapsulant for encapsulating the transparent encapsulant. The transparent encapsulant has a light-pervious portion formed at a position corresponding to and above a sensor zone of the sensor chip. The light-pervious portion is exposed from the light-impervious encapsulant. Light may penetrate the light-pervious portion, without using an additional cover board, thereby reducing manufacturing steps and costs. The above arrangement avoids prior-art problems of poor reliability caused by a porous encapsulant and poor signal reception caused by interference of ambient light entering into a conventional chip only encapsulated by a transparent encapsulant.

摘要： 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.
