(57) Abstract: An object of the present invention is to realize a bump manufacturing method and a semiconductor device with improved bump manufacturing yield. SOLUTION: A forming step of forming a bump on a dummy wafer, a dicing step of dicing the dummy wafer to form a dummy chip, an inspection step of inspecting a bump formed on the dummy wafer, and the inspection step of the dummy chip The method is configured to include a transfer step of transferring the bumps of the dummy chip, which has passed the above, to the actual chip on which the circuit is formed. |
