The invention provides a stackable semiconductor device and a fabrication method thereof, including providing a wafer having a plurality of dies mounted thereon, both the die and the wafer having an active surface and a non-active surface opposing one another respectively, wherein each die has a plurality of solder pads formed on the active surface thereof and a groove formed between adjacent solder pads to form a first metal layer therein that is electrically connected to the solder pads; subsequently thinning the non-active surface of the wafer to where the grooves are located to expose the first metal layer therefrom, and forming a second metal layer on the non-active surface of the wafer for electrically connecting with the first metal layer; and separating the dies to form a plurality of stackable semiconductor devices. Thereby, the first and second metal layers formed on the active surface and the non-active surface of the semiconductor device can be stacked and connected to constitute a multi-die stack structure, thereby increasing integration without increasing the area of the stacked dies. Further, the problems known in the prior art of poor electrical connection, complicated manufacturing process and increased cost as a result of using wire bonding and TSV can be avoided.

A sensor semiconductor device and a method for fabricating the same are proposed. A sensor chip is mounted on a substrate, and a dielectric layer and a circuit layer are formed on the substrate, wherein the circuit layer is electrically connected to the substrate and the sensor chip. The dielectric layer is formed with an opening for exposing a sensor region of the sensor chip.

Therefore, the sensor semiconductor device is fabricated in a cost-effective manner, and circuit cracking and a know good die (KGD) problem are prevented.

The present invention relates to a semiconductor package with a heat sink. There is at least one chip adhered to the substrate and the heat sink is constituted by a planar plate and a support for supporting the planar plate to a height for positioning the planar plate above the chip. The planar plate has a top surface exposed outside a resin body used for encapsulating the chip and the heat sink, and a bottom surface opposed to the top surface. The planar plate further has a thick portion formed on the bottom surface relative to the position of the chip, wherein there is a gap formed between the end surface of the thick portion and the chip to prevent the heat sink from directly contacting with the chip, and an end surface of the thick portion has a plurality of flow channels formed along the flowing direction of the molding gate to avoid the formation of void in the gap so as to increase the yield rate of products.
