Patent ID: 7229859

Claim:
A method of forming a device, the method comprising: applying a first solution to form a first applied film over a portion of a substrate, the first applied film being patterned, the first solution including a first solvent and a first solute; heating the first applied film at a temperature ranging from 250° C. to 500° C. to form a first film over the portion, the first solvent being evaporated during a period in which the heating of the first applied film is carried out; applying a second solution to form a second applied film over the portion of the substrate, the second applied film being patterned, the second solution including a second solvent and a second solute; heating the second applied film at a temperature ranging from 250° C. to 500° C. to form a second film over the portion, the second solvent being evaporated during a period in which the heating of the second applied film is carried out; applying a dispersion liquid to form a third applied film over the portion of the substrate, the dispersion liquid including a dispersion medium and a dispersoid, the dispersoid being a metal particle with a size of 80 to 100 angstroms; and heating the third applied film at a temperature ranging from 250° C. to 500° C. to form a third film over the portion.
