Abstract
A semiconductor device includes a wiring board; a stack of semiconductor chips disposed over the wiring board, each of the semiconductor chip comprising via electrodes, the semiconductor chips being electrically coupled through the via electrodes to each other, the semiconductor chips being electrically coupled through the via electrodes to the wiring board; a first seal that seals the stack of semiconductor chips; and a second seal that covers the first seal. The first seal is smaller in elastic modulus than the second seal.
