    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 stackable semiconductor device and a manufacturing method thereof are disclosed. The method includes providing a wafer comprised of a plurality of chips, wherein a plurality of solder pads are formed on the active surface of each chip, and a plurality of grooves are formed between the solder pads of any two adjacent ones of the chips; forming a dielectric layer on regions between the solder pads of any two adjacent ones of the chips ; forming a metal layer on the dielectric layer electrically connected to the solder pads and forming a connective layer on the metal layer, wherein the width of the connective layer is smaller than that of the metal layer; cutting along the grooves to break off the electrical connection between adjacent chips; thinning the non-active surface of the wafer to the extent that the metal layer is exposed from the wafer; and separating the chips to form a plurality of stackable semiconductor devices. Accordingly, a multi-chip stack structure can be obtained by stacking and electrically connecting a plurality of semiconductor devices through the electrical connection between the connective layer of a semiconductor device and the metal layer of another semiconductor device, thereby effectively integrating more chips without having to increase the stacking area, and further the problems of poor electrical connection, complicated manufacturing processes and high costs known in the prior art can be avoided.
