  • Patent number: 12298672
    Abstract: Some implementations described herein provide an exposure tool and associated methods of operation in which a scanner control system generates a scanner route for an exposure recipe such that the distance traveled by a substrate stage of the exposure tool along the scanner route is reduced and/or optimized for non-exposure fields on a semiconductor substrate. In this way, the scanner control system increases the productivity of the exposure tool, reduces processing times of the exposure tool, and increases yield in a semiconductor fabrication facility in which the exposure tool is included.

  • Patent number: 12265336
    Abstract: An exposure tool is configured to remove contaminants and/or prevent contamination of mirrors and/or other optical components included in the exposure tool. In some implementations, the exposure tool is configured to flush and/or otherwise remove contaminants from an illuminator, a projection optics box, and/or one or more other subsystems of the exposure tool using a heated gas such as ozone (O3) or extra clean dry air (XCDA), among other examples. In some implementations, the exposure tool is configured to provide a gas curtain (or gas wall) that includes hydrogen (H2) or another type of gas to reduce the likelihood of contaminants reaching the mirrors included in the exposure tool. In this way, the mirrors and one or more other components of the exposure tool are cleaned and maintained in a clean environment in which radiation absorbing contaminants are controlled to increase the performance of the exposure tool.

  • Patent number: 12219123
    Abstract: A method for rendering data of a three-dimensional image adapted to an eye position and a display system are provided. The method is used to render the three-dimensional image to be displayed in a three-dimensional space. In the method, a three-dimensional image data used to describe the three-dimensional image is obtained. The eye position of a user is detected. The ray-tracing information between the eye position and each lens unit of a multi-optical element module forms a region of visibility (RoV) that may cover a portion of the three-dimensional image in the three-dimensional space. When coordinating the physical characteristics of a display panel and the multi-optical element module, a plurality of elemental images can be obtained. The elemental images form an integral image that records the three-dimensional image data adapted to the eye position, and the integral image is used to reconstruct the three-dimensional image.

  • Publication number: 20240385537
    Abstract: A reticle is pre-heated prior to an exposure operation of a semiconductor substrate lot to reduce substrate to substrate temperature variations of the reticle in the exposure operation. The reticle may be pre-heated while being stored in a reticle storage slot, while being transferred from the reticle storage slot to a reticle stage of an exposure tool, and/or in another location prior to being secured to the reticle stage for the exposure operation. In this way, the reduction in temperature variation of the reticle in the exposure operation provided by pre-heating the reticle may reduce overlay deltas and misalignment for the semiconductor substrates that are processed in the exposure operation. This increases overlay performance, increases yield of the exposure tool, and increases semiconductor device quality.
