Abstract

WAFER PROCESSING METHOD OF THE DISCLOSURE A wafer processing method for processing a wafer having devices on the front side is provided. The wafer processing method includes a back grinding step of grinding the wafer to form a recess and an annular reinforcing portion surrounding the recess on the back side of the wafer, and a dividing step of cutting the wafer along division lines formed on the front side of the wafer. In the back grinding step, a taper surface is formed between the bottom surface of the recess and the annular reinforcing portion. The taper surface is inclined with respect to a direction perpendicular to the bottom surface of the recess. In the dividing step, a cutting blade is lowered to start cutting at a position radially inside the outer circumference of the wafer and is subsequently raised to stop cutting at another position radially inside the outer circumference of the wafer.
