A METHOD FOR MAKING A SEMICONDUCTOR DEVICE THAT INCLUDES A METAL GATE ELECTRODE
摘要
<p>A method for making a semiconductor device is described. That method comprises forming a hard mask and an etch stop layer on a patterned sacrificial gate electrode layer. After first and second spacers are formed on opposite sides of that patterned sacrificial layer, the patterned sacrificial layer is removed to generate a trench that is positioned between the first and second spacers. At least part of the trench is filled with metal layer.</p>
