  • Publication number: 20080200039
    Abstract: The invention is directed to a nitridation process for a wafer. The nitridation process comprises steps of disposing the wafer on a top surface of a chuck in a nitridation process tool, wherein a plurality of concentric pipe coils is disposed close to the bottom surface of the chuck. Then, the chuck is heated and the chuck is regionally cooling down by applying a coolant into the concentric pipe coils, wherein the flow rates of the coolant in the concentric pipe coils are different from each other. Furthermore, a plasma nitridation process is performed on the wafer.
