摘要:
A substrate having at least one silicon device is provided. A nickel platinum alloy layer is formed on the substrate. A rapid thermal process is performed to react the nickel platinum alloy layer with the silicon device to produce a nickel platinum silicide. A passivation layer is formed on the nickel platinum silicide followed by using a solution consisting of nitric acid and hydrochloric acid to remove unreacted portions of the nickel platinum alloy layer.
