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： This invention provides a sensor semiconductor package and a method for fabricating the same. The method includes: mounting on a substrate a sensor chip having a sensor area; electrically connecting the sensor chip and the substrate by means of bonding wires; forming on a transparent member an adhesive layer with an opening corresponding in position to the sensor area; and mounting the transparent member on the substrate via the adhesive layer while heating the substrate, such that the adhesive layer melts, to thereby encapsulate the periphery of the sensor chip and the bonding wires while exposing the sensor area from the adhesive layer. Thus, the sensor area is sealed by the transparent member cooperative with the adhesive layer, making the sensor semiconductor package thus-obtained dam-free, light, thin, and compact, and incurs low process costs. Also, the product reliability is enhanced since the bonding wires are encapsulated by the adhesive layer without severing concern.

摘要： 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.
