Abstract:
A method includes forming a transistor, which includes forming a gate dielectric on a semiconductor region, forming a gate electrode over the gate dielectric, and forming a source/drain region extending into the semiconductor region. The method further includes forming a source/drain contact plug over and electrically coupling to the source/drain region, and forming a gate contact plug over and in contact with the gate electrode. At least one of the forming the gate electrode, the forming the source/drain contact plug, and the forming the gate contact plug includes forming a metal nitride barrier layer, and depositing a metal-containing layer over and in contact with the metal nitride barrier layer. The metal-containing layer includes at least one of a cobalt layer and a metal silicide layer.

Claim (Index 16):
An integrated circuit device comprising:\n a transistor comprising:\n a semiconductor region; \n a gate stack overlying the semiconductor region; \n a source/drain region extending into the semiconductor region and on a side of the gate stack; and \n a contact plug electrically connected to one of the gate stack and the source/drain region, wherein the contact plug comprises:\n a cobalt nitride layer; \n a cobalt silicide layer over and contacting the cobalt nitride layer; and \n a cobalt-containing layer over and contacting the cobalt silicide layer.
