Abstract

In a POP type semiconductor device comprising a second semiconductor package as an upper package stacked on a first semiconductor package as a lower package, a plurality of main surface-side lands formed on a first wiring substrate of the first semiconductor package are disposed distributively on both sides of a chip mounting region as a boundary positioned at a central part of a main surface of the first wiring substrate, thus permitting the adoption of a through molding method. Consequently, a first sealing body formed on the main surface of the first wiring substrate in the first semiconductor package as a lower package extends from one second side of the first wiring substrate toward a central part of the other second side of the same substrate.
