    摘要: A semiconductor package and a fabrication method thereof are disclosed. The fabrication method includes the steps of providing a semiconductor chip having an active surface and a non-active surface opposing to the active surface, roughening a peripheral portion of the non-active surface so as to divide the non-active surface into the peripheral portion formed with a roughened structure and a non-roughened central portion, mounting the semiconductor chip on a chip carrier via a plurality of solder bumps formed on the active surface, forming an encapsulant on the chip carrier to encapsulate the semiconductor chip. The roughened structure formed on the peripheral portion of the non-active surface of the semiconductor chip can reinforce the bonding between the semiconductor chip and the encapsulant, and the non-roughened central portion of the non-active surface of the semiconductor chip can maintain the structural strength of the semiconductor chip.

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.

    摘要: 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.
