A stacked semiconductor package and a method for manufacturing the same are presented which exhibit a reduced electrical resistance and an increased junction force. The semiconductor package includes at least two semiconductor chips stacked upon each other. Each semiconductor chip has a plurality of bonding pads formed on upper surfaces and has via-holes. First wiring lines are located on the upper surfaces of the semiconductor chips, on the surfaces of the via-holes, and respectively connected onto their respective bonding pads. Second wiring lines are located on lower surfaces of the semiconductor chips and on the surfaces of the respective via-holes which connect to their respective first wiring lines. The semiconductor chips are stacked so that the first wiring lines on an upper surface of an upwardly positioned semiconductor chip are respectively joined with corresponding second wiring lines formed on a lower surface of a downwardly positioned semiconductor chip.

The present invention relates to a magnetic cover that is coupled to a body of a product by means of a magnetic force, wherein the magnetic cover does not have any screw hole thereon since no screws are required to couple the magnetic cover to the body of the product, thereby providing good outer appearance to the product and conducting easy and convenient coupling and removing operations. In addition, even when the coupling and removing are carried out repeatedly or carelessly, no damage or deformation occurs, and further, no tool like a driver is needed for the coupling or removing.
