Abstract
A semiconductor chip and a wiring board are coupled to each other through conductor posts. The centers of conductor posts situated above openings at the outermost periphery shift from the centers of the openings in a direction away from the center of the semiconductor chip. When a region where each of the conductor posts and an insulating layer are overlapped with each other is designated as an overlapped region, the width of the overlapped region more on the inner side than the opening is smaller than the width of the overlapped region more on the outer side than the opening. Thus, while stress applied to the conductor posts is relaxed, coupling reliability between the semiconductor chip and the wiring board is retained.
