Abstract:
A semiconductor device includes a wafer and a dicing saw tape that is laminated to a back surface of the wafer. An active surface of the wafer is opposite the back surface of the wafer. The semiconductor device further includes a lamination tape disposed in contact with the wafer. The lamination tape includes an under-film layer contacting the active surface of the wafer. The lamination tape further includes an adhesive layer contacting the under-film layer.
