Abstract

It has been found that electrically "coupled noise" between metal lines on a dielectric substrate for packaging I/C chips, which is associated with long line lengths, can be reduced by providing material with a high dielectric constant (Epsilon(r)) in close proximity over the lines, while leaving an air gap between the lines.
