Patent ID: 8329554

Claim:
A method of making a semiconductor device, comprising: providing a wafer having a plurality of bumps formed on a surface of the wafer; forming an under-film layer over the bumps formed on the surface of the wafer to completely cover all portions of the bumps with the under-film layer; after forming the under-film layer, forming an adhesive layer over the under-film layer; after forming the adhesive layer, attaching a support layer over the adhesive layer; grinding a back surface of the wafer, wherein the support layer provides structural support to the wafer during the grinding process; following the grinding process, laminating a dicing saw tape to the back surface of the wafer; removing the support layer to expose the adhesive layer which remains disposed over the under-film layer; and after removing the support layer, removing the adhesive layer to expose the under-film layer, wherein all portions of the bumps remain completely covered by the under-film layer after removing the adhesive layer.
