Abstract
A device includes a wiring substrate. A first semiconductor-chip has a first face, a second face, and a first side face between an outer edge of the first face and an outer edge of the second face, where the first side face is a first condition plane. The first semiconductor-chip is located above the wiring substrate. A second semiconductor-chip has a third face, a fourth face, a second side face between an outer edge of the third face and an outer edge of the fourth face, and a through electrode passing through at least a semiconductor substrate between the third face and the fourth face. The second side face is the first condition plane and a second condition plane having more irregularities than the first condition plane. The second semiconductor-chip is located between the wiring substrate and the first semiconductor-chip. The resin is located around the first and second semiconductor-chips.
