  • Patent number: 12210295
    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.
