METHOD OF FABRICATING DESIRED PATTERN OF ELECTRONICALLY FUNCTIONAL MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method of forming a desired pattern of electronically functional material 3 on a substrate 1.

SOLUTION: The method comprises the steps of: creating a first layer of patterning material 2 on the substrate 1 whilst leaving areas of the substrate exposed to define the desired pattern; printing a suspension comprising particles of the electronically functional material 3 in a liquid dispersant, to which the patterning material is impervious, on the patterning material and the exposed substrate; removing at least some of the liquid dispersant from the suspension to consolidate the particles; and applying a first solvent to the consolidated particles which is capable of solubilizing the patterning material 2 and to which the consolidated particles are pervious so that the patterning material is removed from the substrate 1 together with any overlying electronically functional material 3.
