Patent ID: 7683479

Claim:
A semiconductor device, comprising: a package substrate equipped with a semiconductor chip thereon, a sealing resin formed on the package substrate for sealing around a periphery of the semiconductor chip, and a plurality of fixing members for fixing a separate component on a side of the package substrate where the semiconductor chip is equipped, so that the semiconductor chip is pressed between the package substrate and the separate component, wherein: each of the fixing members have a hook formed on the tip thereof and extending above the upper side of the semiconductor chip, and one end of each of the fixing members is buried in the sealing resin such that the fixing members are buried in the sealing resin along a circle, a plurality of guiding slots for guiding the hooks inside the separate component along the circle are provided on a side of the separate component facing the package substrate in such a way as to face the hooks, each guiding slot corresponding to a respective fixing member, and a rotary locking structure is provided, whereby the hook of each of the fixing members is inserted into the respective guiding slot, the separate component is rotated by a predetermined angle with respect to the package substrate along a concentric circle, and the hook of each of the fixing members travels inside the respective guiding slot, so that the separate component is pulled into contact with the semiconductor chip.
