  • Publication number: 20250110414
    Abstract: Some implementations described herein provide a reticle cleaning device and a method of use. The reticle cleaning device includes a support member configured for extension toward a reticle within an extreme ultraviolet lithography tool. The reticle cleaning device also includes a contact surface disposed at an end of the support member and configured to bond to particles contacted by the contact surface. The reticle cleaning device further includes a stress sensor configured to measure an amount of stress applied to the support member at the contact surface. During a cleaning operation in which the contact surface is moving toward the reticle, the stress sensor may provide an indication that the amount of stress applied to the support member satisfies a threshold. Based on satisfying the threshold, movement of the contact surface and/or the support member toward the reticle ceases to avoid damaging the reticle.

  • Publication number: 20250113087
    Abstract: The present disclosure describes techniques for implementing video segmentation. A video is divided into a plurality of clips. Each of the plurality of clips comprises several frames. Axial-trajectory attention is applied to each of the plurality of clips by a first sub-model. Clip features corresponding to each of the plurality of clips are generated by the first sub-model. A set of object queries corresponding to each of the plurality of clips is generated based on the clip features by a transformer decoder. Trajectory attention is applied to refine sets of object queries corresponding to the plurality of clips by a second sub-model. Video-level segmentation results are generated based on the refined object queries.
