Abstract: A manufacturing method of a semiconductor device comprises the following steps. First, a substrate is provided, at least one fin structure is formed on the substrate, and a metal layer is then deposited on the fin structure to form a salicide layer. After depositing the metal layer, the metal layer is removed but no RTP is performed before the metal layer is removed. Then a RTP is performed after the metal layer is removed.
