  • Patent number: 7314768
    Abstract: In regard to an electroconductive pattern including a high resistivity region partially, by forming a pattern with a photosensitive resin, making the pattern absorb liquid containing a metal component, and baking this, an electroconductive film of metal oxide is formed, this electroconductive film is further covered by a gas shielding layer, and portions which are not shielded are reduced selectively to be made low resistance metal film regions. Since the material which constitutes the electroconductive pattern is hardly removed, a load concerning material reuse is mitigated and material cost is reduced.

  • Patent number: 7115432
    Abstract: A fine electrode and wiring pattern with a good adhesive property is easily formed using a water-based solution easy to handle and small in environmental load, thereby improving a stability of a manufacturing process of an image-forming apparatus in the case where the water-based solution is used in the manufacturing process. A base pattern is formed using a base pattern forming material for electrode and wiring material absorption which is a water-based solution containing a water-soluble photosensitive resin component and a water-soluble metallic compound including rhodium, bismuth, ruthenium, vanadium, chromium, tin, lead, or silicon. An organic metallic compound is absorbed in the base pattern and then baking is conducted to form electrodes and wirings.
