A method is provided of making a semiconductor package with a heat spreader in which a chip carrier module plate consisting of a plurality of array-arranged chip carriers is mounted with at least one chip on each of the chip carriers. A heat spreader module plate is attached to the chips, with an interface layer formed on a top surface of the heat spreader module plate. The chip carrier module plate, the chips and the heat spreader module plate are encapsulated. Adhesion force between the interface layer and the encapsulant is larger than that between the interface layer and the heat spreader module plate, and adhesion force between the interface layer and the heat spreader module plate is smaller than that between the heat spreader module plate and the encapsulant.

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.

A heat dissipation unit and a semiconductor package having the same are disclosed. The semiconductor package includes a carrier; an electronic component mounted on and electrically connected to the carrier; a heat dissipation unit, which includes a flat section attached to the electronic component, extension sections connected to the flat section, and a heat dissipation section connected to the extension sections; and an encapsulant encapsulating the electronic component and the heat dissipation unit, wherein stress releasing sections are at least disposed at intersectional corners between the extension sections and the flat section so as to prevent projections from being formed by concentrated stresses in a punching process of the heat dissipation unit, thereby maintaining flatness of the flat section and further preventing circuits of the electronic component from being damaged due to a contact point produced between the electronic component and the flat section in a molding process.

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.
