Abstract:
1. A semiconductor device production method comprising the steps of: preparing a wafer on which a plurality of integrated circuits are formed on a principal face; forming a rewiring which is electrically connected to the integrated circuits via a pad electrode; forming an electrode terminal on the rewiring; forming a first resin layer by sealing at least the rewiring and the electrode terminal formed on the principal face of the wafer with a first resin; processing a first dicing from a side of a back face of the wafer to the principal face of the wafer or halfway to the first resin layer when the first resin layer is formed; forming a second resin layer by sealing a cut line outlined upon the first dicing and the back face of the wafer continuously with a second resin; and processing a second dicing while leaving the second resin layer which covers a side face outlined upon the first dicing.
