Abstract
One device includes a first chip having first electrodes on one surface, and a rough portion on another surface. The device also includes a second chip having second electrodes on one surface, and third electrodes electrically connected to the second electrodes and disposed on another surface, and stacked on the first chip so the third electrodes are electrically connected to the first electrodes. The device includes a resin layer covering the first and second chips so at least the other surface of the first chip and the one surface of the second chip are exposed. The device also includes a wiring board having connection pads formed on one surface, and stacked on the second chip so the connection pads are electrically connected to the second electrodes. The device includes a sealing resin portion formed on the wiring board to cover the first chip, the second chip, and the resin layer.
