A semiconductor package and a method for fabricating the same are provided. The method includes providing a substrate having recognition points and a heat sink having openings, and placing the heat sink on the substrate with the recognition points being exposed through the openings; using a checking system to inspect the recognition points through the openings so as to ensure that the heat sink is placed at a predetermined position on the substrate; and attaching the heat sink to the substrate via an adhesive. By the above semiconductor package and method, there is no need to form positioning holes in the substrate such that any adverse effect on the circuit layout and reliability of the semiconductor package is avoided, and any positional shifting of the heat sink relative to the substrate can be determined in a real time manner.

A heat-dissipating semiconductor package and a fabrication method thereof are provided. A semiconductor chip is mounted and electrically connected to a substrate. A heat-dissipating structure includes a heat sink and at least one supporting portion, wherein the supporting portion is attached to the substrate at a position outside a predetermined package area for the semiconductor package, and the semiconductor chip is disposed under the heat sink. An encapsulant is formed on the substrate to encapsulate the semiconductor chip and the heat-dissipating structure, wherein a projection area of the encapsulant on the substrate is larger in size than the predetermined package area. A cutting process is performed along edges of the predetermined package area to remove parts of the encapsulant, the supporting portion and the substrate, which are located outside the predetermined package area, so as to form the semiconductor package integrated with the heat-dissipating structure.

An electronic carrier board is provided, including a carrier, at least two paired bond pads formed on the carrier, and a protective layer covering the carrier. The protective layer is formed with openings corresponding in position to the two bond pads. The openings are aligned in the same direction and expose at least a first sidewall and a second sidewall of each of the two bond pads. The first sidewall is perpendicular to an alignment direction of the bond pads and the second sidewall is parallel to the alignment direction of the bond pads. A distance between the first sidewall of at least one of the bond pads and a corresponding side of a corresponding one of the openings is at least about 50 μm greater than a distance between the second sidewall of the at least one bond pad and a corresponding side of the corresponding opening.

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. An opening is formed in the protective layer to expose at least three sides of each of the paired bond pads. The protective layer includes at least one independent residual portion located in the opening and between the paired bond pads, such that an electronic component is mounted on the independent residual portion and electrically connected to the bond pads. A groove without a dead space is formed between the electronic component and the carrier, such that a molding compound for encapsulating the electronic component can flow through the groove to fill the opening and a space under the electronic component and encapsulate the at least three sides of each of the bond pads.

A heat-dissipating semiconductor package structure and a method for manufacturing the same is disclosed. The method includes: disposing on and electrically connecting to a chip carrier at least a semiconductor chip and a package unit; disposing on the top surface of the package unit a heat-dissipating element having a flat portion and a supporting portion via the flat portion; receiving the package unit and semiconductor chip in a receiving space formed by the flat portion and supporting portion of the heat-dissipating element; and forming on the chip carrier encapsulant for encapsulating the package unit, semiconductor chip, and heat-dissipating element. The heat-dissipating element dissipates heat generated by the package unit, provides EMI shielding, prevents delamination between the package unit and the encapsulant, decreases thermal resistance, and prevents cracking.

This invention provides a method for fabricating a semiconductor device and a carrier applied therein. The method includes the steps of: disposing a chip-mounted substrate in an opening of a carrier; forming at least a storage aperture and at least an inspection aperture in the carrier; infusing an adhesive into the storage aperture to fill a gap between the substrate and carrier with the adhesive by capillarity; determining whether the inspection aperture is filled with the adhesive to ascertain whether the gap is completely filled with the adhesive; in response to a positive result, performing a molding process to form a molding compound for encapsulating the chip; and performing implantation of solder ball and a singulation process to form a semiconductor device with desirable dimensions. The inspection aperture is inspected with a naked eye to determine whether the gap is completely filled with the adhesive, thereby reducing inspection costs and increasing yields of products with no additional packaging costs.

A heat dissipating semiconductor package and a heat dissipating structure thereof are provided. The heat dissipating structure includes an outer surface, consecutive recessed step portions, and a pressure-releasing groove. The outer surface is exposed from an encapsulant made of a molding compound. The step portions are formed at an edge of the outer surface and have decreasing depths wherein the closer a step portion to a central position of the outer surface, the smaller the depth of this step portion is. The pressure-releasing groove is disposed next to and deeper than the innermost one of the step portions. A molding compound flows to the step portions and absorbs heat from an encapsulation mold quickly, such that a flowing speed of the molding compound is reduced. Pressure suffered by air remaining at the step portions is released through the pressure-releasing groove, thereby preventing flashes of the molding compound and resin bleeding.
