Abstract:
A method of removing particles from a wafer is provided. The method is adopted after a process for removing unreactive metal of a salicide process or after a salicide process and having oxide residue remaining on a wafer or after a chemical vapor deposition (CVD) process that resulted with particles on a wafer. The method includes performing at least two cycles (stages) of intermediate rinse process. Each cycle of the intermediate rinse process includes conducting a procedure of rotating the wafer at a high speed first, and then conducting a procedure of rotating the wafer at a low speed.
