A multi-chip module has at least two semiconductor chips. Each of the semiconductor chips has chip electrodes of the semiconductor chip, electrically conductive interconnections for electrically connection with the chip electrodes, electrically conductive lands for electrically connection with the interconnections, external terminals placed on the lands, and a stress-relaxation layer intervening between the lands and the semiconductor chip. The semiconductor chips are placed on a mounting board via the external terminals. The distance between farthest ones of external terminal positioned at an outermost end portions of said second semiconductor chip is smaller than that of the first semiconductor chip.
