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.

A heat dissipating semiconductor package and the fabrication method therefor are provided. The fabrication method for the heat dissipating semiconductor package mainly includes steps of: containing a substrate having a chip mounted thereon in an aperture of a carrier, wherein the carrier has an electroconductive layer; allowing a heat dissipating structure having supporting portions to be mounted on and electrically connected to the electroconductive layer of the carrier via the supporting portions thereof while heat dissipating structure being mounted on the chip; after an encapsulation process and removing a part of the encapsulant above the heat dissipating sheet by lapping to expose a surface of the heat dissipating structure from the encapsulant, depositing and forming a metal passivation layer on the surface of the heat dissipating structure by electroplating for preventing the heat dissipating structure from oxidizing.

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.

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.
