    摘要: A method of manufacturing a metal-oxide-semiconductor transistor device is disclosed. In the method, a silicon nitride spacer is formed and will be removed after an ion implantation process used to form a source/drain region and a salicide process used to form a metal silicide layer on the surface of the source/drain region and the gate electrode. The metal silicide layer is formed to comprise silicon (Si), nickel (Ni) and at least one metal selected from a group consisting of iridium (Ir), iron (Fe), cobalt (Co), platinum (Pt), palladium (Pd), molybdenum (Mo), and tantalum (Ta); therefore, when the silicon nitride spacer is removed by etching, the metal silicide layer is not damaged.

    摘要: A metal-oxide-semiconductor transistor device is disclosed, in which, a silicon nitride spacer has been formed but is removed after an ion implantation process to form a source/drain region and a salicide process to form a metal silicide layer on the surface of the source/drain region and the gate electrode are performed. The metal silicide layer comprises silicon, nickel and at least one metal selected from a group consisting of iridium, iron, cobalt, platinum, palladium, molybdenum, and tantalum; therefore, when the silicon nitride spacer is removed by etching, the metal silicide layer is not damaged.
