Abstract:
Provided is a method of manufacturing a semiconductor device capable of dividing a wafer with metal formed on a rear surface thereof into individual pieces while suppressing chipping and defective cuts. The method of manufacturing a semiconductor device includes: forming a metal layer on a rear surface of a semiconductor substrate; performing blade dicing for the metal layer; and performing stealth dicing® for the semiconductor substrate.

Claim (Index 2):
A method of manufacturing a semiconductor device, comprising:\n forming modified layers inside a semiconductor substrate by irradiating the semiconductor substrate with laser light along streets in the semiconductor substrate; forming a metal layer on a rear surface of the semiconductor substrate; dicing the metal layer with a blade along the streets; and dicing the semiconductor substrate by applying an external force to the semiconductor substrate in which the modified layers are formed.
