Method of forming electrically conductive lines with controlled coefficient of thermal expansion

Abstract

Disclosed herein is a method for forming electrically conductive lines with a controlled thermal expansion coefficient (CTE), the method comprising: applying a suspension on a surface of a substrate, the suspension comprising a solvent and a solid component, the solid component comprising a mixture of at least two types of electrically conductive nanoparticles, sintering the suspension to form the electrically conductive lines, and removing a non-sintered portion of the suspension, wherein the at least two types of electrically conductive nanoparticles comprise: a first type of electrically conductive nanoparticles having a positive CTE and a second type of electrically conductive nanoparticles having a different CTE than the first type of conductive nanoparticles, and wherein a ratio between the at least two types of electrically conductive nanoparticles determines a final CTE of the electrically conductive lines.
