Curable Composition, Temporary Bonding Material, and Method for Temporarily Bonding Component Part and Substrate By Same

摘要

A first curable composition has flowability and include a photopolymerizable group-containing silicone compound (A), a photopolymerization initiator, a photoacid generator and at least one kind of metal compound selected from the group consisting of metal carbonates, metal hydroxides and metal oxides. This curable composition provides a temporary bonding material capable of easily temporarily bonding a component part and a substrate, without trapping an air bubble in a temporary bonding surface of the component, and allowing easy separation of the component part and the substrate after performing various processing on the component part.
