Title: Wafer processing method
Inventor: SUGITANI TETSUKAZU
IPC: B23K26/53
Filed: 2017-07-24
Abstract: To provide a wafer processing method which enables the increase the number of chips obtained from a wafer.SOLUTION: A wafer processing method comprises a laser beam irradiation step of forming a quality-modified layer S along each scheduled division line L in a wafer W to produce a crack 3 to run from the quality-modified layer S to a surface Wa of the wafer W, which splits a device layer 2, whereby the wafer can be divided to respective device layers 2 by the cracks 3 produced in the wafer W without forming a cutting groove on a side of the surface Wa of the wafer W. This eliminates the need for setting a large width of a scheduled division line L, enables the increase in the number of chips C obtained from a wafer, and enables the rise in the productivity of the chips C. After the laser beam irradiation step, the wafer W is cut by a cutting blade 61 from a backside Wb to form each cutting groove M, and to remove the quality-modified layer S. Therefore, the quality-modified layer S is never left on the chips C, and the flexural strength of the chips C is increased.SELECTED DRAWING: Figure 7
