Printed ink structure using fluoropolymer template

摘要

A method is provided for controlling printed ink horizontal. cross-sectional areas using fluoropolymer templates. The method initially forms a fluoropolymer template overlying a substrate. The fluoropolymer template has a horizontal first cross-sectional dimension. Then, a primary ink is printed overlying the fluoropolymer template having a horizontal second cross-sectional dimension less than the first cross-sectional dimension. In the case of a fluoropolymer line having a template length greater than a template width, where the template width is the first cross-sectional dimension, printing the primary ink entails printing a primary ink line having an ink length greater than an ink width, where the ink width is the second cross-sectional dimension. In one aspect, the method prints a plurality of primary ink layers, each primary ink layer having an ink width less than the template width. Each overlying primary ink layer can be printed prior to solvents in underlying primary ink layers evaporating.
