Abstract

A semiconductor device-manufacturing method includes a laminated wafer formation step and a dicing step. In the laminated wafer formation step, a metal plate is first laid on one side of a wafer with a solder material interposed, and then the metal plate and the wafer are subjected to decompression pressing to form a one-piece structure. As a result, a laminated wafer is obtained. In the dicing step, the laminated wafer is diced into laminated chips.
