A semiconductor process is provided. First, a substrate having a dielectric layer formed thereon is provided. Thereafter, an interconnection structure including copper is formed in the dielectric layer. Afterwards, a metal layer is formed on the dielectric layer. The metal layer is then patterned to form a pad. An annealing process is performed, wherein the gas source for the annealing process includes hydrogen in a concentration of 50% to 90%.
