Patent number: 11861283Abstract: A placement method for integrated circuit design is provided. Each net is considered as a soft module. The net will receive a larger penalty if it covers more routing congested regions. Therefore, it is easier to move the nets away from routing congested regions. In addition, to relieve local congestion, a novel inflation method is proposed to expand the area of a cluster according to its internal connectivity intensity and routing congestion occupied by the cluster. Accordingly, it can get better routability and wirelength.Type: GrantFiled: November 15, 2021Date of Patent: January 2, 2024Assignees: GLOBAL UNICHIP CORPORATION, TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY, LTD.Inventors: Chen-Fa Tsai, Che-Li Lin, Chia-Min Lin, Chung-Wei Huang, Liang-Chi Zane

Patent number: 9489876Abstract: An inspection method including following steps is provided. A pixel array substrate including a plurality of pixel units is in contact with a photoelectric inspection device. A plurality of electrical signals is inputted to the pixel units of the pixel array substrate and the photoelectric inspection device. Based on an optical property of the photoelectric inspection device, the pixel units of the pixel array substrate are being examined on whether they are normal or not. Moreover, an inspection apparatus realizing the inspection method is also provided.Type: GrantFiled: February 12, 2014Date of Patent: November 8, 2016Assignee: E Ink Holdings Inc.Inventors: Chuan-Feng Liu, Jen-Shiun Huang, Pei-Lin Huang, Shi-Lin Li, Chen-Fa Tsai, Yung-Sheng Chang

Patent number: 8976517Abstract: An electronic device includes a shell, a display module and a cushion. The shell includes a bottom plate and a top plate. The top plate defines an opening. The display module is disposed in the shell and faces the opening. The display module is spaced from the bottom plate of the shell. The cushion is disposed between the display module and the bottom plate of the shell, and brought into contact with the display module for cushioning the display module when an external force is applied to the display module.Type: GrantFiled: June 28, 2012Date of Patent: March 10, 2015Assignee: E Ink Holdings Inc.Inventors: Wan-Tien Chen, Ming-Sheng Chiang, Wen-Chang Lu, Hung-Yi Tsai, Yuan-Chih Tsai, Chu-Kuang Tseng, Chi-Ming Wu, Jen-Shiun Huang, Tsung-Ting Lee, Chen-Fa Tsai
