Abstract:
A method includes forming a transistor including forming a source/drain region on a side of a dummy gate stack, forming a first Inter-Layer Dielectric (ILD) covering the source/drain region, and replacing the dummy gate stack with a replacement gate stack. The method further includes forming a second ILD over the first ILD and the replacement gate stack, and forming a lower source/drain contact plug electrically coupling to the source/drain region. The lower source/drain contact plug penetrates through both the first ILD and the second ILD. A third ILD is formed over the second ILD. A gate contact plug is formed in the second ILD and the third ILD. An upper source/drain contact plug is formed overlapping and contacting the lower source/drain contact plug. The upper source/drain contact plug penetrates through the third ILD. The upper source/drain contact plug and the gate contact plug are formed of different materials.

Claim (Index 12):
The integrated circuit device of  claim 11 , wherein the upper source/drain contact plug comprises:\n an additional metal nitride layer comprising an additional bottom portion, and additional sidewall portions over and connected to the additional bottom portion; and an additional metal region over the additional bottom portion and encircled by the additional sidewall portions of the additional metal nitride layer, wherein the additional metal region is free from nitrogen therein.
