Semiconductor integrated circuit device and its manufacturing method

摘要

A semiconductor wafer which has finished formation of a relocating wiring layer thereon is stored and after determination of a design, solder bumps are formed over bump lands (one end of the relocating wiring layer) in accordance with a pattern which differs with a design, whereby a function or characteristic depending on the design is selected. The semiconductor wafer is then cut into a plurality of semiconductor chips, whereby a wafer level CSP is available.
