Patent number: 9786489Abstract: A method of cleaning post-etch residues on a copper line includes providing a copper line which is divided into a first region and a second region. A dielectric layer is formed on the copper line. After that, the dielectric layer is etched to form openings in the dielectric layer. A number of openings within the first region is more than a number of openings in the second region. During the etching process, a potential difference is formed between the first region and the second region of the copper line. Finally, the dielectric layer and the copper line are cleaned by a solution with a PH value. The PH value has a special relation with the potential difference.Type: GrantFiled: March 17, 2017Date of Patent: October 10, 2017Assignee: UNITED MICROELECTRONICS CORP.Inventors: Ming Sheng Xu, Ching-Long Tsai, Hua-Kuo Lee, Guangjun Huang

Patent number: 9030794Abstract: An electronic fuse apparatus is connected between a power side and a system side. The electronic fuse apparatus mainly includes an electronic fuse, a short-circuit protection switch, a current-sensing module, and a digital control module. The current-sensing module detects an operating current which flows from the power side to the system side. The digital control module generates a control signal to control the electronic fuse. When the current-sensing module detects that the operating current is over-current, the digital control module generates the high-level control signal to turn off the electronic fuse, thus providing an over-current protection. When a short-circuit fault occurs at the system side, the short-circuit protection switch is turned on to turn off the electronic fuse, thus providing a short-circuit protection.Type: GrantFiled: October 9, 2013Date of Patent: May 12, 2015Assignee: Delta Electronics, Inc.Inventors: Ching-Long Tsai, Yi-Hsin Leu, Ming-Tsung Hsieh, Der-Min Liu

For example, an RFID tag includes a conductive cage that shields the components of the RFID tag from electrostatic discharge. The conductive cage includes a first conductive shield on a first side of a substrate of the RFID tag and a second conductive shield on a second side of the substrate.
