Abstract
A method of fabricating a semiconductor device is described. A conductive layer is formed on a substrate. A spacer is formed on a sidewall of the conductive layer. A thin metallic layer is formed over the substrate. An ion implantation step is performed. A first seeding layer is formed between the first metallic layer and the conductive layer. A second seeding layer is formed between the first metallic layer and the substrate. A second metallic layer is formed over the substrate. An annealing step is performed to form a self-aligned silicide layer on the conductive layer. The first metallic layer and the second metallic layer that do not react are removed.
