Abstract:
A method of controllably bonding a thin sheet having a thin sheet bonding surface with a carrier having a carrier bonding surface, by depositing a carbonaceous surface modification layer onto at least one of the thin sheet bonding surface and the carrier bonding surface, incorporating polar groups with the surface modification layer, and then bonding the thin sheet bonding surface to the carrier bonding surface via the surface modification layer. The surface modification layer may include a bulk carbonaceous layer having a first polar group concentration and a surface layer having a second polar group concentration, wherein the second polar group concentration is higher than the first polar group concentration. The surface modification layer deposition and the treatment thereof may be performed by plasma polymerization techniques.
