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 15):
A device comprising:\n a transistor comprising:\n a first source/drain region at a top surface of a semiconductor substrate; and \n a gate electrode in a first dielectric layer; \n a diode comprising:\n an anode at the top surface of the semiconductor substrate; \n a guard ring in a well region of the semiconductor substrate; a second dielectric layer over the first dielectric layer; a first conductive via in the second dielectric layer, the first conductive via having a first width, and the first conductive via being electrically connected to and disposed directly over the first source/drain region; a second conductive via in the second dielectric layer, the second conductive via having a second width, and the second conductive via being electrically connected to and disposed directly over the anode; a third conductive via in the second dielectric layer, the third conductive via having a third width, the third conductive via being electrically connected to and disposed directly over the guard ring, wherein at least one of the second width or third width is greater than the first width.
