Abstract

A process of forming an integrated circuit including an MOS transistor, in which a pre-metal deposition cleanup prior to depositing metal for silicide formation includes an HF etch, a first SCetch, a piranha etch and a second SCetch, so that a native oxide on the source/drain regions is less the 2 nanometers thick before deposition of the silicide metal. A process of forming a metal silicide layer on an integrated circuit containing an MOS transistor, in which a pre-metal deposition cleanup prior to depositing metal for silicide formation includes an HF etch, a first SCetch, a piranha etch and a second SCetch, so that a native oxide on the source/drain regions and the MOS gate is less the 2 nanometers thick before deposition of the silicide metal.
