Abstract:
A method of making a semiconductor device that includes forming a dielectric stack over a substrate and patterning a contact region in the dielectric stack, the contact region having side portions and a bottom portion that exposes the substrate. The method also includes forming a dielectric barrier layer in the contact region to cover the side portions and forming a conductive blocking layer to cover the dielectric barrier layer, the dielectric stack, and the bottom portion of the contact region. The method can include forming a conductive layer over the conductive blocking layer and forming a conductive barrier layer over the conductive layer. The method can further include forming a silicide region in the substrate beneath the conductive layer.

Claim (Index 16):
A method for forming a semiconductor contact plug, the method comprising:\n depositing a dielectric stack over a substrate; forming a contact region in the dielectric stack, the contact region extending into the substrate and having side portions and a bottom portion that exposes the substrate; depositing a first metal layer in the contact region to cover the side portions and bottom portion of the contact region; depositing a second metal layer over the first metal layer; depositing a conductive barrier layer over the second metal layer; and performing a first annealing process and a second annealing process to form a silicide region in the substrate, wherein the first annealing process is performed before the formation of the conductive barrier layer, and the second annealing process is performed after the formation of the conductive barrier layer.
