Semiconductor apparatus, and method of manufacturing semiconductor apparatus

A semiconductor apparatus manufacturing method, comprising:

• providing a semiconductor wafer in which a semiconductor chip is formed, the semiconductor chip being provided with a predetermined circuit and a plurality of electrode pads on a main surface;
• forming bump electrodes on the plurality of electrode pads;
• providing a wired board whose area is smaller than that of the semiconductor chip, and which includes land parts corresponding to the plurality of electrode pads formed on the semiconductor chip respectively, and a wiring for electrically connecting the electrode pads and the land parts;
• mounting the wired board on the semiconductor chip which is determined as a non-defective product of the semiconductor chips formed on the semiconductor wafer by electrically connecting the bump electrode pad of the semiconductor chip and the wiring electrically connected to the land part;
• and
• cutting and separating the semiconductor wafer on which the wired board is mounted onto each of the semiconductor chips, and picking up the separated semiconductor chip.
