Abstract
A method is provided for forming a metal contact plug. In one step, a substrate, which is an Si substrate or an SiOsubstrate, is etched to form a contact hole. In one step, a dielectric liner layer is formed on a sidewall of the contact hole. In one step, the metal contact plug that is in contact with the dielectric liner layer is formed in the contact hole. In one step, an implantation process is performed on the substrate, so as to implant dopants having an atomic size greater than that of Si into the substrate.
