Abstract
A stacked semiconductor device includes a first semiconductor package and a second semiconductor package stacked thereon, and further includes a plate member interposed between the first semiconductor package and the second semiconductor package. The plate member has a plate body, protruding strips protruding toward its edges from the plate body, and leg portions respectively provided on the protruding strips. Each of the leg portions is disposed on a surface, which opposes one surface of a wiring substrate, of the protruding strip, and contacts the one surface of the wiring substrate. Thus, defective connection of connecting terminals due to warping of the wiring substrate and loading inclination of the first semiconductor package is reduced, resulting in an improved yield.
