A semiconductor package with a photosensitive chip and a fabrication method thereof are provided. A substrate having a core is prepared. A solder mask layer is applied over a surface of the core and formed with an opening to expose a continuous peripheral portion on the surface of the core. At least one photosensitive chip is mounted on and electrically connected to the substrate. An encapsulation dam is formed on the continuous peripheral portion of the core and surrounds the chip. The dam includes a shoulder portion adjacent to and flush with the solder mask layer, and a protruded support portion surrounding the shoulder portion. A lid is attached to the support portion of the dam for sealing the dam such that the chip is received in a space defined by the substrate, the dam and the lid.

A semiconductor package and a method for fabricating the same are provided. A leadframe including a die pad and a plurality of peripheral leads is provided. A carrier, having a plurality of connecting pads formed thereon, is attached to the die pad, wherein a planar size of the carrier is greater than that of the die pad, allowing the connecting pads on the carrier to be exposed from the die pad.

摘要:
A semiconductor package includes two substrates each having a plurality of electrical connection pads, at least one chip mounted on each of the substrates, an encapsulation body formed on each of the substrates for encapsulating the chip, and an cover for receiving the substrates and the chips therein. The chip is electrically connected to the electrical connection pads. The electrical connection pads are exposed from the cover and located on the same surface or oppositely arranged. The substrates and the cover each substantially has a rectangular shape, with a longer side of each of the substrates being vertical to a longer side of the cover. The semiconductor package is incorporated with multiple chips to enhance the performance and memory capacity thereof, and the substrates are smaller than those in the prior art and thus are more cost-effective to fabricate.
