Granted: 2000-11-11
Abstract: A self-aligned silicide layer is manufactured on a substrate. A MOS device and a shallow trench isolation are provided on the substrate wherein the MOS device includes a gate, a spacer and a doped region and the shallow trench is filled with silicon oxide as insulator. A silicon layer is deposited on the surface of the gate, the spacer and the doped region by physical vapor deposition such as metal plasma. Such metal plasma of the sputter processes make the silicon or the metal to be ionized. The ionized silicon or metal are anisotropically deposited on the surface of the substrate and the silicon layer on the spacer is removed. A salicide layer is formed from a refractory metal layer on the silicon layer by two-step anneal such as rapid thermal anneal. Since the silicon layer is used as a source of self-aligned silicide layer, the silicide layer can be formed on the top of spacer and the silicon oxide layer above the trench. Photolithography is performed to remove the salicide layer on the trench isolation.
