  • OPTICAL DIAGNOSTICS OF SEMICONDUCTOR PROCESS USING HYPERSPECTRAL IMAGING
    Publication number: 20230097892
    Abstract: Disclosed are embodiments of an improved apparatus and system, and associated methods for optically diagnosing a semiconductor manufacturing process. A hyperspectral imaging system is used to acquire spectrally-resolved images of emissions from the plasma, in a plasma processing system. Acquired hyperspectral images may be used to determine the chemical composition of the plasma and the plasma process endpoint. Alternatively, a hyperspectral imaging system is used to acquire spectrally-resolved images of a substrate before, during, or after processing, to determine properties of the substrate or layers and features formed on the substrate, including whether a process endpoint has been reached; or before or after processing, for inspecting the substrate condition.

  • FOCUS RING FOR A PLASMA-BASED SEMICONDUCTOR PROCESSING TOOL
    Publication number: 20230066418
    Abstract: A focus ring for a plasma-based semiconductor processing tool is designed to provide and/or ensure etch rate uniformity across a wafer during a plasma etch process. The focus ring may include an angled inner wall that is angled away from a center of the focus ring to direct a plasma toward the wafer. The angle of the angled inner wall may be greater than approximately 130 degrees relative to the top surface of the wafer and/or may be less than approximately 50 degrees relative to an adjacent lower surface of the focus ring to reduce and/or eliminate areas of overlapping plasma on the wafer (which would otherwise cause non-uniform etch rates). Moreover, an inner diameter may be configured to be in a range of approximately 209 millimeters to 214 millimeters to further reduce and/or eliminate areas of overlapping plasma on the wafer.
