Patent number: 12189311Abstract: 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.Type: GrantFiled: May 12, 2023Date of Patent: January 7, 2025Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Yen-Hsun Chen, Yi-Zhen Chen, Jhan-Hong Yeh, Han-Lung Chang, Tzung-Chi Fu, Li-Jui Chen

Patent number: 11698591Abstract: An EUV photolithography system utilizes a baseplate of an EUV pod to unload an EUV reticle from a chuck within an EUV scanner. The baseplate includes a top surface and support pins extending from the top surface. The when the reticle is unloaded onto the baseplate, the support pins hold the reticle at relatively large distance from the top surface of the baseplate. The support pins have a relatively low resistance. The large distance and low resistance help ensure that particles do not travel from the baseplate to the reticle during unloading.Type: GrantFiled: August 31, 2021Date of Patent: July 11, 2023Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Yi-Zhen Chen, Yen-Hsun Chen, Jhan-Hong Yeh, Tzung-Chi Fu, Han-Lung Chang, Li-Jui Chen
