摘要： A semiconductor package with a heat sink is provided in which at least one chip is mounted on the substrate and covered by a heat sink. The heat sink is formed with a plurality of grooves or holes at positions in contact with the substrate, allowing an adhesive material to be applied between the heat sink and the substrate and filled into the grooves or holes for attaching the heat sink onto the substrate. The adhesive material filled into the grooves or holes provides an anchoring effect for firmly positioning the heat sink on the substrate. Therefore, it is not necessary to form predetermined holes on the substrate for being coupled to fixing members such as bolts, and incorporation of the heat sink would not affect trace routability and arrangement of input/output connections such as solder balls on the substrate and would not lead to cracks of the chip.

摘要： A flip-chip semiconductor device is proposed, including a substrate, a plurality of stiffeners disposed at peripheral areas of the substrate, with a gap formed between each of the adjacent stiffeners; at least a semiconductor chip mounted on an area of the substrate surrounded by the stiffeners via flip-chip technique; and a beat sink attached to the semiconductor chip. By such arrangement, warpage of the semiconductor device may be prevented. As an opening is formed at an appropriate position of the stiffener structure, distortion of the stiffener may be avoided. Further, as the beat sink is not attached to the stiffener, solder bumps may be free from thermal stress due to mismatch in coefficient of thermal expansion between the heat sink and the substrate while preventing delamination of the heat sink caused by thermal stress.

摘要： A bump structure of a semiconductor package and a method for fabricating the same are provided. The bump structure is used to connect a semiconductor element to a carrier of the semiconductor package. The fabrication method primarily employs an electroplating process to form the bump structure including an under bump metallurgy (UBM) layer, at least one I-shaped conductive pillar, and a solder material. This allows fine-pitch electrical connection pads to be arranged in the semiconductor package, and also provides an enhanced support structure and a sufficient height between the semiconductor element and the carrier.
