Abstract
A semiconductor device includes: a first semiconductor chip including an electrode pad on one surface of the first semiconductor chip; a multilayer chip stack that is disposed on the one surface of the first semiconductor chip to be connected to the electrode pad; a columnar spacer that is disposed on the one surface of the first semiconductor chip; and an underfill resin. The multilayer chip stack includes a plurality of second semiconductor chips each of which comprises a connection terminal. The connection terminal of one of the second semiconductor chips is directly connected to the electrode pad. Another one of the second semiconductor chips is mounted on the one of the second semiconductor chips. A gap between the first semiconductor chip and the one of the second semiconductor chips and a gap between adjacent ones of the second semiconductor chips are filled with the underfill resin.
