A production method for a semiconductor device is provided whereby, when peeling a support body from an attached wafer, melting of a sheet-shaped resin composition pasted to the other surface of the wafer can be suppressed. The method comprises: preparing a support body-attached wafer, said support body-attached wafer having the support body bonded, via a temporary fixing layer, to one surface of the wafer having a through electrode formed therein; preparing a dicing tape-integrated sheet-shaped resin composition having a sheet-shaped resin composition having an external shape smaller than the other surface of the wafer formed upon a dicing tape; pasting the other surface of the support body-attached wafer to the sheet-shaped resin composition in the dicing tape-integrated sheet-shaped resin composition; and melting the temporary fixing layer by a solvent and peeling the support body away from the wafer. |
