Abstract
The invention simplifies the manufacturing processes and increases the yield. A semiconductor wafer equipped with a plurality of semiconductor chip forming sections is prepared. An electrical characteristic examination is conducted for each of the semiconductor chip forming sections to determine good product sections or bad product sections. At least another segmented semiconductor chip is electrically connected to each of the semiconductor chip forming sections that are determined to be good product sections.
