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 semiconductor package with a heat sink and a method for fabricating the same are proposed. The heat sink is provided with a rigid and thermally resistant detach member on a top surface thereof, and is attached via its bottom surface to a chip mounted on a chip carrier. The detach member is sized larger than the heat sink and can be easily removed from the top surface of the heat sink. Subsequently, a molding process is performed to form an encapsulant for completely encapsulating the chip, the heat sink and the detach member. Then, a singulation process is performed to cut along predetermined cutting lines located between sides of the heat sink and corresponding sides of the detach member. Finally, the detach member and a portion of the encapsulant formed on the detach member are removed from the heat sink. The above fabrication method reduces the packaging cost.
