    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 semiconductor package includes a substrate; a chip mounted on a surface of the substrate; a lid having a flat portion and a support portion extending from the flat portion, wherein the support portion is attached to the substrate, with the chip being encompassed by the flat portion, the support portion and the substrate, and at least one cut-away portion is formed at an outer edge of a surface of the support portion attached to the substrate; an adhesive for attaching the lid to the substrate and filling the cut-away portion to allow an applied amount of the adhesive to be observed from the cut-away portion; and a plurality of solder balls mounted on another surface of the substrate. The applied amount of the adhesive can be adjusted optimally by provision of the cut-away portion to improve bonding strength between the lid and substrate and prevent flash of the adhesive.
