Abstract

A method of converting a hydrophobic surface of a dielectric layer to a hydrophilic surface is described. That method comprises forming a dielectric layer on a substrate, then operating a PECVD reactor to generate a plasma that converts the surface of that layer from a hydrophobic surface to a hydrophilic surface. Also described is a method for making a semiconductor device that employs this technique.
