Publication number: 20190064675Abstract: Embodiments of the present disclosure relate to methods for defect inspection. After pattern features are formed in a structure layer, a dummy filling material having dissimilar optical properties from the structure layer is filled in the pattern features. The dissimilar optical properties between materials in the pattern features and the structure layer increase contrast in images captured by an inspection tool, thus increasing the defect capture rate.Type: ApplicationFiled: December 6, 2017Publication date: February 28, 2019Applicant: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Ta-Ching YU, Shih-Che WANG, Shu-Hao CHANG, Yi-Hao CHEN, Chen-Yen KAO, Te-Chih HUANG, Yuan-Fu HSU

Patent number: 9665007Abstract: An EUV collector is rotated between or during operations of an EUV photolithography system. Rotating the EUV collector causes contamination to distribute more evenly over the collector's surface. This reduces the rate at which the EUV photolithography system loses image fidelity with increasing contamination and thereby increases the collector lifetime. Rotating the collector during operation of the EUV photolithography system can induce convection and reduce the contamination rate. By rotating the collector at sufficient speed, some contaminating debris can be removed through the action of centrifugal force.Type: GrantFiled: August 29, 2016Date of Patent: May 30, 2017Assignee: Taiwan Semiconductor Manufacturing Co., Ltd.Inventors: Shang-Chieh Chien, Shu-Hao Chang, Jui-Ching Wu, Tsung-Yu Chen, Tzu-Hsiang Chen, Ming-Chin Chien, Chia-Chen Chen, Jeng-Horng Chen
