Patent number: 10014251Abstract: A semiconductor device with the metal fuse is provided. The metal fuse connects an electronic component (e.g., a transistor) and a existing dummy feature which is grounded. The protection of the metal fuse can be designed to start at the beginning of the metallization formation processes. The grounded dummy feature provides a path for the plasma charging to the ground during the entire back end of the line process. The metal fuse is a process level protection as opposed to the diode, which is a circuit level protection. As a process level protection, the metal fuse protects subsequently-formed circuitry. In addition, no additional active area is required for the metal fuse in the chip other than internal dummy patterns that are already implemented.Type: GrantFiled: March 5, 2016Date of Patent: July 3, 2018Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Chen-Chung Lai, Kang-Min Kuo, Yen-Ming Peng, Gwo-Chyuan Kuoh, Han-Wei Yang, Yi-Ruei Lin, Chin-Chia Chang, Ying-Chieh Liao, Che-Chia Hsu, Bor-Zen Tien

Patent number: 9463673Abstract: A tire positioning method includes the following steps. Four wireless signals transmitted from four tires of a car are received by a wireless signal receiver. Each wireless signal includes a uniaxial acceleration. One of the tires which is located at a first location is identified according to the intensity of the wireless signals. The first location is the closest to the wireless signal receiver. When the car makes a turn, one of the tires which is located at a second location is identified according to the direction of each uniaxial acceleration. The second location and the first location are both located at one side of the car. The direction of the uniaxial acceleration of the tire which is located at the first location is identical to that of the tire which is at the second location. The side of the car is right side or left side.Type: GrantFiled: December 9, 2014Date of Patent: October 11, 2016Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Shih-Ching Huang, Chin-Chia Chang, Chung-Yuan Su
