  • Publication number: 20240042472
    Abstract: Light can be used to monitor coating a liquid on a substrate. By directing the light to a spot on the substrate, when the liquid passes through the spot, some light will be reflected, while some light will be scattered. Monitoring this behavior can indicate whether a substrate has been successfully coated with the liquid, as well as identifying defects. Further, coating times can be monitored to make process adjustments.

  • Publication number: 20240046446
    Abstract: Embodiments of systems and methods are disclosed for inspecting features formed within and/or on a semiconductor substrate. More specifically, the present disclosure provides various embodiments of systems and methods to automatically adjust one or more parameters (or camera settings) used by a camera system to capture a stack of images of a feature formed within and/or on a semiconductor substrate before the images are processed to generate a three-dimensional (3D) reconstruction of the feature. In some embodiments, the disclosed systems and methods may filter the images included within the stack of images used for 3D reconstruction and dynamically determine when the camera system has captured enough images for 3D reconstruction of the feature. In doing so, the disclosed systems and methods may provide a more complete and accurate 3D reconstruction of the feature, while improving throughput of the wafer inspection process.

  • Patent number: 11049700
    Abstract: Systems and related methods are disclosed for atmospheric plasma processing of microelectronic workpieces, such as semiconductor wafers. For disclosed embodiments, a radio frequency (RF) generator generates an RF signal that is distributed to one or more plasma sources within a process chamber. The process chamber has an atmospheric pressure between 350 to 4000 Torr. The plasma sources are then scanned across a microelectronic workpiece to apply plasma gasses generated by the plasma generators to the microelectronic workpiece. The plasma sources can be individually scanned and/or combined in arrays for scanning across the microelectronic workpiece. Linear and/or angular movement can be applied to the plasma sources and/or the microelectronic workpiece to provide the scanning operation. Various implementations are disclosed.

  • Patent number: 10522384
    Abstract: A processing system is disclosed, having a process chamber that houses a substrate for exposure of a surface of the substrate to a travelling electromagnetic (EM) wave. The processing system also includes an EM wave transmission antenna configured to launch the travelling EM wave into the process chamber for the travelling EM wave to propagate in a direction substantially parallel to the surface of the substrate. The processing system also includes a power coupling system configured to supply EM energy into the EM wave transmission antenna to generate the travelling EM wave at a prescribed output power and in a prescribed EM wave mode during treatment of the substrate. The EM wave is recycled in the processing system in order to increase the efficiency of the microwave power use and eliminate the complexity of the resistive load cooling.

  • Patent number: 10215704
    Abstract: Described herein are technologies to facilitate computed tomographic techniques to help identifying chemical species during plasma processing of a substrate (e.g., semiconductor wafer) using optical emission spectroscopy (OES). More particularly, the technology described herein uses topographic techniques to spatially resolves emissions and absorptions in at least two-dimension space above the substrate during the plasma processing (e.g., etching) of the substrate. With some implementations utilize optical detectors positioned along multiple axes (e.g., two or more) to receive incident incoming optical spectra from the plasma chamber during the plasma processing (e.g., etching) of the substrate. Because of the multi-axes arrangement, the incident incoming optical spectra form an intersecting grid.
