Abstract
Disclosed is a semiconductor light emitting chip () that is composed of: a substrate (), which has the C plane of a sapphire single crystal as the front surface, and the side surfaces () configured of planes that intersect all the planes equivalent to the M plane of the sapphire single crystal, and which includes modified regions () in the side surfaces (), the modified regions being formed by laser radiation; and a light emitting element (), which is provided on the substrate front surface () of the substrate (). In the semiconductor light emitting chip, a tilt of the substrate side surfaces with respect to the substrate front surface is suppressed. Also disclosed is a method for processing the substrate.
