  • Patent number: 12347692
    Abstract: Embodiments of the present disclosure relates to a wet bench processing including an in-situ pre-treatment prior to performing the first set of wet bench operations. The pre-treatment may include a pre-clean operation and/or a pre-heat operation. The pre-treatment may be performed in one of the existing ONB tanks without requiring adding new tanks to an existing wet bench tool. The pre-clean operation removes particles from a batch of wafers to avoid or reduce cross-contamination and defect issues, thus improving the yield rate of the wet bench process. The pre-heat operation provides better control and stabilize the temperature in the CHB tank to stabilize the process, such as to stabilize an etch rate.

  • Patent number: 12028642
    Abstract: A target tracking system includes an observation module, a dynamic tracking module, a control module and an aiming module. The observation module captures an observation frame including a tracked-object image of a tracked-object and an aiming point image and detects a distance between the observation module and the tracked-object. The dynamic tracking module analyzes the observation frame to obtain a lag correction vector between the aiming point image and the tracked-object image, and obtains a feed-forward correction vector according to the lag correction vector and the distance. The control module generates a control command representing the lag correction vector and a control command representing the feed-forward correction vector. The aiming module moves according to the control commands to control the aiming point image to align with the tracked-object image and control the aiming point image to lead the tracked-object image.
