A METHOD FOR MAKING A SEMICONDUCTOR DEVICE HAVING A METAL GATE ELECTRODE |
摘要 |
<p>A method for making a semiconductor device is described. That method comprises forming a dielectric layer on a substrate, and forming an impurity containing metal layer on the dielectric layer. A metal gate electrode is then formed from the impurity containing metal layer. Also described is a semiconductor device that comprises a metal gate electrode that is formed on a dielectric layer, which is formed on a substrate. The metal gate electrode includes a sufficient amount of an impurity to shift the workfunction of the metal gate electrode by at least about 0.1 eV.</p> |
