Abstract:
1. A pattern forming material comprising: a thermal sensitive material layer formed on a target substrate; a first light-to-heat converting layer formed between the thermal sensitive material layer and the target substrate; and a second light-to-heat converting layer formed on a surface of the thermal sensitive material layer opposite to the first light-to-heat converting layer, wherein the thermal sensitive material layer, which does not comprise a light-to-heat material, is interposed between the first and second light-to-heat converting layers and the first and second light-to-heat converting layers consists essentially of Ge—Sb—Te alloys; Ag—In—Sb—Te alloys; Ag—In—Sb—Te—V alloys; lithium niobate; methylnitro aniline; or any combinations thereof, and wherein the first and second light-to-heat converting layers absorb a first activation light radiated thereon and convert the absorbed activation light into heat.
