Patent ID: 8025553

Claim:
A method of grinding a back-side surface of a wafer having a face-side surface provided with devices, said method comprising: a resin film covering step of covering said face-side surface of said wafer with a resin film; a wafer holding step of holding said wafer, with said face-side surface exposed, by a holding means of a cutting apparatus of which the facing angle relative to a machining plane of a cutting member held by a rotating body can be controlled to be substantially parallel; a wafer angle controlling step of regulating the facing angle of said holding means relative to said cutting member so as to control said face-side surface of said wafer held by said holding means to be substantially parallel to said machining plane of said cutting member; a resin film cutting step of cutting a surface of said resin film to be flat by said cutting member being rotated; and a back-side grinding step of holding said wafer by a holding means of a grinding apparatus with the cut surface of said resin film being directed downward and grinding said exposed back-side surface of said wafer.
