Abstract
Methods of manufacturing a semiconductor structure are provided. One of the methods includes the following operations. A substrate is received, and the substrate includes a first conductive region and a second conductive region. A first laser anneal is performed on the first conductive region to repair lattice damage. An amorphization is performed on the first conductive region and the second conductive region to enhance silicide formation to a desired phase transformation in the subsequent operations. A pre-silicide layer is formed on the substrate. A thermal anneal is performed to the substrate to form a silicide layer from the pre-silicide layer. A second laser anneal is performed on the first conductive region and the second conductive region.
