Abstract:
1. A semiconductor wafer processing method for planarizing an additional layer formed on the front side of a semiconductor wafer, said semiconductor wafer processing method comprising: a semiconductor wafer holding step of holding said semiconductor wafer by using holding means included in a cutting device in a condition where the front side of said semiconductor wafer is exposed, said cutting device including a rotating member and a cutting member supported to said rotating member, said cutting member forming a cut surface, said holding means having a holding surface on which said semiconductor wafer is held, the angle of said holding surface to said cut surface being adjustable to substantially zero; an additional layer cutting step of flat cutting said additional layer formed on the front side of said semiconductor wafer by using said cutting member rotating with said rotating member; and an additional layer polishing step of polishing said additional layer after said additional layer cutting step.
