Abstract

A method of manufacturing a salicide layer is described. A substrate having a memory region and a logic circuit region is provided, wherein the memory region comprises a first gate structure and a first source/drain region and the logic circuit region comprises a second gate structure and a second source/drain region. A first salicide layer is formed on the second gate structure and the second source/drain region in the logic circuit region. A dielectric layer is formed over the substrate. A portion of the dielectric layer is removed to expose the first gate structure and the first salicide layer above the second gate structure. A second salicide layer is formed on the first and the second gate structure.
