摘要:
A method for forming a silicide layer on a substrate. A substrate with a silicon surface is provided. Nitrogen is incorporated into the silicon surface by a plasma treatment, to form a nitridized silicon surface. A metal layer is formed on the nitridized silicon surface. The substrate having the metal layer thereon is annealed to form a silicide layer between the metal layer and the substrate.
