Abstract
A fabrication method for a gate spacer. The method comprises provision of a substrate with a gate formed thereon, after which a SiN,spacer is formed on the gate sidewall. The substrate is then covered with a SiO,layer. A part of the SiO,layer is removed until the surface of the SiO,layer is lower than the top surface of the gate. A portion of the SiN,layer is removed to expose the top edge of the gate spacer and to increase the exposed area of the gate. The SiO,layer is consequently removed.
