Abstract
A carrier substrate includes a base layer, an antireflection layer, and an energy absorption layer, wherein the antireflection layer is formed on one surface of the base layer and allows an elastic wave generated by a first laser beam transmitted through an element adhesively bonded to the antireflection layer to be transmitted through the base layer without being reflected towards the element, the first laser beam being applied to the element through a source substrate of the element, and the energy absorption layer is formed between the base layer and the antireflection layer to be aligned with the element, and evaporates upon energy absorption.
