ABSTRACT:
A ball grid array packaged semiconductor device mounted on a mounting board and including pads formed within a package and are connected to signal lines of a bare chip by bonding wires. There are formed first vias extending from the respective pads to a bottom surface of a package, and second vias extending from the same respective pads to a top surface of the package to form continuous vias. This makes it possible to connect the mounting boards to the top and bottom surfaces of the package, thereby enabling reduction of the wiring density of wiring patterns on the mounting boards, and thereby facilitating routing of the wiring patterns on the mounting boards. The semiconductor device is capable of reducing wiring density of the wiring pattern on the mounting board.
