Abstract:
1. A semiconductor device comprising: a stack of semiconductor chips including a first semiconductor chip and a second semiconductor chip, the first semiconductor chip having a first group of bump electrodes and a second group of bump electrodes directed toward the second semiconductor chip, the second semiconductor chip having a group of bump electrodes directed toward the first semiconductor chip in corresponding relationship to the first semiconductor chip; and a supporting plate for supporting the stack of semiconductor chips, the supporting plate having an outer portion located outside the first semiconductor chin and provided with terminals in corresponding relationship to the second group of bump electrodes of the first semiconductor chip for enabling direct contact with the second group of bump electrodes; wherein the supporting plate is arranged at an intermediate height between an uppermost surface and a lowermost surface of the stack of semiconductor chips; wherein the supporting plate is formed with at least one opening in which the first group of bump electrodes of the first semiconductor chip are held in direct contact with the group of bump electrodes of the second semiconductor chip for wireless connection, the supporting plate also having an inner supporting portion interposed between the first semiconductor chip and the second semiconductor chip, the at least one opening separating the inner portion of the supporting plate from the outer portion of the separating plate; and wherein the second group of bump electrodes are held in direct contact with the terminals of the supporting plate for wireless connection at the at least one opening.
