    摘要: The method described herein involves a method of forming metal gates and metal contacts in a common fill process. The method may involve forming a gate structure comprising a sacrificial gate electrode material, forming at least one conductive contact opening in a layer of insulating material positioned adjacent the gate structure, removing the sacrificial gate electrode material to thereby define a gate electrode opening, and performing a common deposition process to fill the conductive contact opening and the gate electrode opening with a conductive fill material.
