Abstract:
A method includes forming a transistor at a surface of a semiconductor substrate, wherein the step of forming the transistor comprises forming a gate electrode, and forming a source/drain region adjacent the gate electrode. First metal features are formed to include at least portions at a same level as the gate electrode. Second metal features are formed simultaneously, and are over and contacting the first metal features. A first one of the second metal features is removed and replaced with a third metal feature, wherein a second one of the second metal features is not removed. A fourth metal feature is formed directly over and contacting the gate electrode, wherein the third and the fourth metal features are formed using a same metal-filling process.

Claim (Index 1):
A device comprising:\n a transistor comprising:\n a first source/drain region at a top surface of a semiconductor substrate; \n a gate electrode in a first dielectric layer; and \n a second source/drain region at the top surface of the semiconductor substrate and disposed on an opposing side of the gate electrode as the first source/drain region; \n a second dielectric layer over the first dielectric layer; a first conductive via in the second dielectric layer, wherein the first conductive via is electrically connected to and disposed directly over the first source/drain region; a second conductive via in the second dielectric layer, wherein the second conductive via is electrically connected to and disposed directly over the second source/drain region; and a gate contact in the second dielectric layer and in direct contact with the gate electrode, wherein the gate contact is physically separated from and wider than the first conductive via and the second conductive via.
