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.

摘要： A fabrication method of under bump metallurgy (UBM) structure is provided. A blocking layer is applied over a surface of a semiconductor element formed with at least one bond pad and a passivation layer thereon. The passivation layer covers the semiconductor element and exposes the bond pad, and the blocking layer covers the bond pad and the passivation layer. The blocking layer is formed with at least one opening at a position corresponding to the bond pad. Metallic layers are formed on a surface of the blocking layer and at the opening. The metallic layers are patterned to form a UBM structure at the opening corresponding to the bond pad. Then the blocking layer is removed. The blocking layer can separate the metallic layers for forming the UBM structure from the passivation layer to prevent metallic residues of the UBM structure from being left on the passivation layer.

摘要： An electronic carrier board and a package structure thereof are provided. The electronic carrier board includes a carrier, at least one pair of bond pads formed on the carrier, and a protective layer covering the carrier. The protective layer is formed with openings for exposing the bond pads. A groove is formed between the paired bond pads and has a length larger than a width of an electronic component mounted on the paired bond pads. The groove is adjacent to one of the paired bond pads and communicates with a corresponding one of the openings where this bond pad is exposed. Accordingly, a clearance between the electronic component and the electronic carrier board can be effectively filled with an insulating resin for encapsulating the electronic component, thereby preventing voids and undesirable electrical bridging between the paired bond pads from occurrence.
