Based upon an innovative concept and technology, "Soft Processing" or "Soft Solution Processing",we can realize the direct fabrication of ceramics films by interfacial reactions between a substrate and a solution at low temperatures. Activating/stimulating those reactions locally and/or moving the reaction point dynamically,Direct Patterning of ceramic films in solution becomes possible without any post heating, masking or etching. They differ from previous patterning methods like "Direct Printing" consisting of multi-step processes including Firing/Sintering of powders. In "Direct Patterning",the chemical driving force of the reaction, A+B=AB, can be utilized for synthesis and also for crystallization and/or consolidation of the compound AB. We have developed the Direct Patterning of CdS, PbS, CaWO4 on papers by ink-jet reaction method and TiO2 and CeO2 patterns by Ink-jet deposition method at < 300 C. Fabrication of BaTiO3 patterns by a laser beam and carbon patterns by a needle electrode directly in solutions have been achieved.
