Filed: 2000-08-10
Abstract: PROBLEM TO BE SOLVED: To reduce the mounting volume and to shorten the length of wiring between semiconductor chips while ensuring the performance of a semiconductor device at the time of mounting the semiconductor chips on a mounting board. SOLUTION: A plurality of semiconductor chips are produced by forming first pad electrodes 8 of an arbitrary wiring layer, forming second pad electrodes 5 of an arbitrary wiring layer different from that of the first pad electrodes 8 at positions different from the first pad electrodes 8 in the horizontal direction, and then forming external terminals of bumps 4 penetrating a semiconductor substrate 10 while conducting with the second pad electrodes 5.
