Prior to a wafer's entry into the fabrication process, its surface must be cleaned to remove any adhering particles and organic/inorganic impurities. Cleaning is a critical process step. Contamination on the wafer surface can cause unreliable electrical properties leading to defective, poor quality semiconductor chips. Continually shrinking device design rules have made cleaning technologies ever more important to achieving acceptable product yields. In modern device fabrication, wafer cleaning procedures can make up 30-40% of the steps in the total manufacturing process.
MKS solutions for wafer cleaning include microwave, plasma, ozone, and process automation products.
