摘要:
A semiconductor device includes a first semiconductor package, a second semiconductor package. The first semiconductor package includes a first semiconductor package base having a first cavity formed therein, a first mount component mounted in the first cavity, and a first magnet disposed on the first semiconductor package base. The second semiconductor package includes a second semiconductor package base having a second cavity formed therein, a second mount component mounted in the second cavity, and a second magnet disposed on the second semiconductor package base so as to adsorb the first magnet. The first semiconductor package and the second semiconductor package are stacked by an adsorption of magnetic force between the first magnet and the second magnet.

PROBLEM TO BE SOLVED: To provide a semiconductor device in which semiconductor packages are layered, the semiconductor device that facilitates attachment and detachment of the semiconductor packages. SOLUTION: A semiconductor package (10) and a semiconductor package (20) are layered by making magnets (22, 23) formed respectively therein attract each other. Through self-alignment effects of the magnet (22) and magnet (23), the semiconductor package (10) and semiconductor package (20) are positioned, such that a contact (13) comes in contact with a pad formed on the semiconductor package (20). At this time, the contact (13) is pressed against the semiconductor package (20) by an elastic member (14) connected to the contact (13) so that the contact (13) can surely come in contact with the pad.

PROBLEM TO BE SOLVED: To provide a semiconductor device of package structure which is suitable for mass production and capable of being connected at a narrow pitch for simultaneously realizing a multiple pin and miniaturization, and to provide its manufacturing method. SOLUTION: A relay board 5-1 is arranged between an upper package and a lower package. Size reduction in solder balls 6 and a pitch reduction can be realized by arranging the relay board 5-1. The relay board 5-1 is set one size larger than that of the upper package and lower package. Underfill can be prevented from leaking and spreading, because the relay board 5-1 is one size larger. A laminated package of high reliability can be realized with many pins, at a narrow pitch, having high mass productivity, and at a low cost. COPYRIGHT: (C)2007,JPO&INPIT
