Patent number: 11984365Abstract: A high atomic number material is applied to one or more surfaces of a semiconductor structure of a wafer. The one or more surfaces are at a depth different from a depth of a surface of the wafer. An electron beam is scanned over the semiconductor structure to cause a backscattered electron signal to be collected at a collector. A profile scan of the semiconductor structure is generated based on an intensity of the backscattered electron signal, at the collector, resulting from the high atomic number material. The high atomic number material increases the intensity of the backscattered electron signal for the one or more surfaces of the semiconductor structure such that contrast in the profile scan is increased. The increased contrast of the profile scan enables accurate critical dimension measurements of the semiconductor structure.Type: GrantFiled: March 19, 2021Date of Patent: May 14, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Pei-Hsuan Lee, Hung-Ming Chen, Kuang-Shing Chen, Yu-Hsiang Cheng, Xiaomeng Chen

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: 20120182275Abstract: A system and a method of compensating background brightness for a display apparatus are disclosed. The display apparatus has a screen for displaying images, and said method comprises steps of: (a) detecting an intensity of ambient light in the front of the screen; (b) obtaining a representative brightness of an image displayed on the screen; (c) determining a backside spotting reference reflective luminance value according to the ambient light intensity and the image representative brightness; and (d) spotting in the rear of the screen by using a lighting module and thus making a spotting intensity to achieve the reference reflective luminance value. The said method and system can reduce eye fatigue and discomfort of viewers.Type: ApplicationFiled: April 6, 2011Publication date: July 19, 2012Applicant: National Taiwan University of Science and TechnologyInventors: Hung-shing Chen, Shih-han Chen

Patent number: 7920740Abstract: A hue segmentation system and method thereof suitable for image devices are described. First, a plurality of hue segments are generated based on color data of a plurality of colors in a color gamut. Then, the area difference between the hue segments and the color gamut is calculated. If the area difference is greater than a predetermined value, the hue segmentation system searches at least one vertex among the hue segments to divide the segments for generating a plurality of additional hue segments. The above-mentioned steps are performed repeatedly until the area difference is less than the predetermined value. Thus fewer hue segments indicate the color gamut of color processing of the image devices to effectively decrease calculation times and save required memory.Type: GrantFiled: October 1, 2007Date of Patent: April 5, 2011Assignee: AU Optronics Corp.Inventors: Te-mei Wang, Hung-shing Chen

Patent number: 7860305Abstract: A color correction system and a method thereof are disclosed. A correction system according to the present invention includes an identification unit, a correction unit, and an adjustment module. The way of correction includes following steps: firstly the identification unit receives an image color data and identifies whether the image color data is a specific or a non-specific color data. Then the correction unit corrects the specific color data for display while the non-specific color data is adjusted by the adjustment module according to the color characteristics of the image output device. Therefore, the image data to be displayed is corrected and display quality of the image output device is improved.Type: GrantFiled: March 8, 2007Date of Patent: December 28, 2010Assignee: Au Optronics CorporationInventors: Te-Mei Wang, Hung-Shing Chen, Jin-Sin Liu, Shih-Han Chen

Publication number: 20070230780Abstract: A hue correction system and a method thereof are disclosed. The hue correction system includes a segmentation unit, a processing unit, and a correction unit. The segmentation unit segments the color gamut of a color output device and a reference device respectively into a plurality of source hue pages and a plurality of reference hue pages. Or only the color gamut of the color output device is segmented into a plurality of source hue pages and a plurality of reference hue pages. The source hue pages and the reference hue pages correspond to each other. Then, the processing unit gets a plurality of hue page conversion factors from the above mentioned hue pages. At last, the correction unit corrects an input color data being input to the color output device according to the source hue pages and the hue page conversion factors.Type: ApplicationFiled: March 22, 2007Publication date: October 4, 2007Inventors: Hung-Shing Chen, Te-Mei Wang, Shih-Han Chen, Jin-Sin Liu
