  • Publication number: 20230309194
    Abstract: Some implementations described herein incorporate a heating system to heat a cover of a bucket. A liquified target material, collected by vanes and/or a transport ring within a vessel of an extreme ultraviolet (EUV) radiation source, flows through a drain port of the transport ring and through a conduit that provides the liquified target material to the bucket through an opening of the cover. By heating the cover, the heating system prevents the liquified target material from solidifying at or near the opening before the liquified target material can flow into the bucket. By preventing the solidifying of the liquid target material, a likelihood of a blockage within the conduit and/or the drain port is reduced.

  • Publication number: 20230280664
    Abstract: A reticle carrier described herein is configured to quickly discharge the residual charge on a reticle so as to reduce, minimize, and/or prevent particles in the reticle carrier from being attracted to and/or transferred to the reticle. In particular, the reticle carrier may be configured to provide reduced capacitance between an inner baseplate of the reticle carrier and the reticle. The reduction in capacitance may reduce the resistance-capacitance (RC) time constant for discharging the residual charge on the reticle, which may increase the discharge speed for discharging the residual charge through support pins of the reticle carrier. The increase in discharge speed may reduce the likelihood that an electrostatic force in the reticle carrier may attract particles in the reticle carrier to the reticle.

  • Publication number: 20230266680
    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.
