Semiconductor chip package and manufacturing method thereof

摘要

A semiconductor chip package comprising a chip with a lid having venting holes hermetically sealed with screws and a manufacturing method thereof are provided. The semiconductor chip package of the present invention comprises a chip such as a central processing unit (CPU) chip generating a large amount of heat; a substrate having upper and lower surfaces, the chip attached to the upper surface of the substrate; external connection terminals extending from the lower surface of the substrate and electrically connected to the chip; a lid attached to the upper surface of the substrate. The lid has a cavity for receiving the chip on a lower surface and venting holes penetrating the lid. The package includes sealing screws for hermetically sealing the venting holes. With the present invention, the venting holes formed through the lid are hermetically sealed without creating any voids or cracks in the sealant as in the prior art.
