Abstract
Abstract A plurality of substrates are stacked on top of each other. A flexible cable serially connects the substrates. Semiconductor packages are mounted on the surfaces of the substrates. An adhesive material bonds adjoining semiconductor packages and holds the semiconductor packages in place with respect to each other. The bottommost substrate is provided with external leads by which the semiconductor module is mounted on the motherboard.
