摘要:
An organic metal precursors containing one or more organic ligands bonded to one or more metal atoms, wherein the organic ligand is rapidly dissociated from the metal atom upon exposure to light and degraded leaving a metal or a metal oxide. By using the organic metal precursors, an electroconductive, metal-containing patterned film can be easily deposited on a substrate at room temperature under atmospheric pressure without using photosensitive resins.
摘要:
A rapid and efficient process of forming a metal-containing pattern by producing, through photoreaction, a difference in solubility between exposed and unexposed areas of a thing film, and developing the film to produce a patterned film, followed by oxidation or reduction to provide a pure metal or metal oxide pattern.

摘要:
An organometallic composition containing an organometallic compound (I) containing Ag, an organometallic compound (II) containing Au, Pd, or Ru, and an organometallic compound (III) containing Ti, Ta, Cr, Mo, Ru, Ni, Pd, Cu, Au, or Al, wherein the metal components of organometallic compounds (II) and (III), respectively, are present in an amount of 0.01˜10 mol % based on the amount of Ag in the organometallic compound (I), and a method of forming a metal alloy pattern using the same. Silver alloy patterns can be obtained through a simplified manufacturing process, which patterns have enhanced heat resistance, adhesiveness, and chemical stability. The method may be applied to making a reflective film for LCD and metal wiring (gate, source, drain electrode) for flexible displays or flat panel displays, and further to CMP-free damascene processing and PR-free ITO film deposition.
