Publication number: 20240144467Abstract: A hot spot defect detecting method and a hot spot defect detecting system are provided. In the method, hot spots are extracted from a design of a semiconductor product to define a hot spot map comprising hot spot groups, wherein local patterns in a same context of the design yielding a same image content are defined as a same hot spot group. During runtime, defect images obtained by an inspection tool performing hot scans on a wafer manufactured with the design are acquired and the hot spot map is aligned to each defect image to locate the hot spot groups. The hot spot defects in each defect image are detected by dynamically mapping the hot spot groups located in each defect image to a plurality of threshold regions and respectively performing automatic thresholding on pixel values of the hot spots of each hot spot group in the corresponding threshold region.Type: ApplicationFiled: January 8, 2024Publication date: May 2, 2024Applicant: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Chien-Huei Chen, Pei-Chao Su, Xiaomeng Chen, Chan-Ming Chang, Shih-Yung Chen, Hung-Yi Chung, Kuang-Shing Chen, Li-Jou Lee, Yung-Cheng Lin, Wei-Chen Wu, Shih-Chang Wang, Chien-An Lin

Publication number: 20210063239Abstract: Disclosures of the present invention describe a method for calibrating laser power. During a laser power calibration of a laser optics product, reference intensity data and reference power data are adopted for generating a reference trend line with a R2 value that is equal to 1. As such, real intensity data that have a residual value smaller than a threshold value are adopted for generating a first trend line in combination with real power data. Moreover, the real intensity data that have a residual value greater than the threshold value are utilized for generating a second trend line in combination with corresponding real power data. Consequently, under an assistance of a predict trend line constituted by the first trend line and the second trend line, the laser power calibration is therefore completed after the laser optics product successively emits a laser beam by a few times.Type: ApplicationFiled: October 22, 2019Publication date: March 4, 2021Inventors: SHIH-CHIEH HSU, WEI-LUNG HUANG, PEI-MING CHANG, PAO-CHUNG CHAO, WEN-CHIH SHEN

Publication number: 20210026461Abstract: Disclosures of the present invention describe an independent inputting device with self-learning function. During a user inputting a vocabulary word and/or a sentence, this independent inputting device can forecast what vocabulary word is that the user desires to input in case of a number of inputted letters of the vocabulary word reaching a threshold integer (?N). Consequently, this independent inputting device automatically completes the inputting of those un-inputted letters of the vocabulary word, such that the user does no longer continue the inputting of those un-inputted letters of the vocabulary word. As such, when the user adopts one input method to edit a program code, write an article or a letter, or make statistical forms, inputting speed of the typed vocabulary words can be apparently increased by this independent inputting device, thereby largely enhancing the user's work efficiency.Type: ApplicationFiled: October 3, 2019Publication date: January 28, 2021Inventors: SHIH-CHIEH HSU, WEN-CHIH SHEN, WEI-LUNG HUANG, PEI-MING CHANG, PAO-CHUNG CHAO
