Abstract:
A semiconductor device and method of forming the same that includes forming a dielectric layer over a substrate and patterning a contact region in the dielectric layer, the contact region having side portions and a bottom portion that exposes the substrate. The method can also include forming a dielectric barrier layer in the contact region to cover the side portions and the bottom portion, and etching the dielectric barrier layer to expose the substrate. Subsequently, a conductive layer can be formed to cover the side portions and the bottom portion of the contact region and the conductive layer can be annealed to form a silicide region in the substrate beneath the bottom portion of the contact region, and the conductive layer can then be selectively removed on the side portions of the contact region. Finally, a surface treatment can be performed in the contact region to form N-rich areas in the dielectric layer and a nitridation region in the substrate, and an adhesion layer can formed in the contact region to cover the side portions and the bottom portion of the contact region.

Claim (Index 21):
A method for forming a semiconductor device, the method comprising:\n etching a contact region in a dielectric layer, the dielectric layer being positioned over a substrate, the contact region having side portions and a bottom portion that exposes the substrate; depositing a dielectric barrier layer in the contact region to partially cover the side portions of the contact region; forming a silicide region located in the substrate beneath the bottom portion of the contact region having a conductive layer that is formed over the silicide region; performing a surface treatment on the side portions and the bottom portion of the contact region that forms a nitridation region adjacent the bottom portion of the contact region within the substrate and N-rich areas along the side portions of the contact region; and depositing an adhesion layer in the contact region to cover the side portions and the bottom portion of the contact region, including the silicide region in the substrate and the dielectric barrier layer.
