Method for manufacturing semiconductor device

Abstract

According to an embodiment, a method for manufacturing a semiconductor device includes forming a slit in a first wafer in which a first semiconductor layer is formed on a first substrate, sticking together the first wafer in which the slit is formed and a second wafer in which a second semiconductor layer is formed on a second substrate, the sticking being performed between a side of the first semiconductor layer and a side of the second semiconductor layer, thinning the first substrate or the second substrate of a member obtained by the sticking, forming an interconnection on a face of the substrate that is thinned, and dicing a member on which the interconnection is formed in accordance with a position of the slit.
