Abstract: A bonding operation to increase the bond between a coating layer and substrate is described. The coating layer may be designed to resist residue on a substrate that covers a display of an electronic device. An adhesion layer including silica (SiO2) and a catalyst or dopant, such as zirconium, may be used to bond the coating layer with the substrate. The dopant can alter the chemical nature of the adhesion layer and increase the number of chemical bonding sites at a bonding surface of the adhesion layer, thereby creating an activated bonding surface. One activated surface of the adhesion layer can be bonded with the substrate, while another activated surface of the adhesion layer can be bonded with the coating layer.
