Patent number: 7646278Abstract: The present invention relates to a high voltage transformer with high magnetic leakage and dual high voltage output, comprising a base and a core set, wherein the base contains a hollow support into which a first core of the core set pierces, and primary coils are wound on both sides of the hollow support, while a plurality of isolation channels is installed for winding first and second secondary coils on external sides of primary coils. First and second slots are opened between the primary coils and the first and second secondary coils respectively, and both slots cut into an internal through hole. When a second core of the core set is placed at one end of the hollow support, extensions at both ends of the second core go through both sides of the first core, together with first and second protrusive parts between the two extensions that are installed within the first and second slots and combined with the first core to form multiple magnetic paths.Type: GrantFiled: August 28, 2008Date of Patent: January 12, 2010Assignee: Taipei Multipower Electronics Co., Ltd.Inventors: Ching-Sheng Yang, Su-Hua Wu, Shu-Chen Wang

Patent number: 7037841Abstract: A method for fabricating a semiconductor device having a dual damascene opening structure. The method includes the steps of providing a substrate having a dielectric layer thereon. A first photoresist layer having a via contact hole pattern is formed on the dielectric layer. A sacrificial layer is formed on the first photoresist layer and fills up the via contact hole pattern. A second photoresist layer having an interconnect trench pattern is formed on the sacrificial layer, thereby exposing the sacrificial layer beneath the interconnect trench pattern. The interconnect trench pattern is transferred to the sacrificial layer using the second photoresist layer as a mask.Type: GrantFiled: February 2, 2004Date of Patent: May 2, 2006Assignee: Winbond Electronics Corp.Inventors: Meng-Wei Wu, En-Shan Liang, Keng-Yao Lee, Su-Hua Wu
