Publication number: 20170271432Abstract: A manufacturing method of an inductor structure includes the following steps. A protection layer is formed on a substrate, such that bond pads of the substrate are respectively exposed form protection layer openings of the protection layer. A conductive layer is formed on the bond pads and the protection layer. A patterned first photoresist layer is formed on the conductive layer. Copper bumps are respectively formed on the conductive layer located in the first photoresist layer openings. A patterned second photoresist layer is formed on the first photoresist layer, such that at least one of the copper bumps is exposed through second photoresist layer opening and the corresponding first photoresist layer opening. A diffusion barrier layer and an oxidation barrier layer are formed on the copper bump. The first and second photoresist layers, and the conductive layer not covered by the copper bumps are removed.Type: ApplicationFiled: June 2, 2017Publication date: September 21, 2017Inventors: Wei-Ming LAI, Yu-Wen HU

Patent number: 7978052Abstract: A microwave control system is applied to control a working system to execute at least one predetermined assignment, and comprises a microwave control unit, a control card and a passive control unit. A microwave illuminator of the microwave control unit is applied to send a microwave signal. After receiving the microwave signal, the control card reflects a reflection signal to the microwave control unit, wakes up from a first sleep mode to enter a first awake mode, and sends a first control signal to the passive control unit. After the microwave control unit receives the reflection signal, the passive control unit wake up from a second sleep mode to enter a second awake mode, and the passive control unit transmits a second control signal in accordance with the first control signal to the working system, so as to control the working system to execute the predetermined assignment.Type: GrantFiled: November 16, 2007Date of Patent: July 12, 2011Assignee: Unified Packet Systems Corp.Inventors: Wei-Cheng Lin, Yu-Wen Hu

Patent number: 6811974Abstract: The invention relates to primer-specific and mispair extension assays for identifying gene variations, such as in different genotypes or subtypes of a given genotype. The assay includes extending a nucleic acid sequence from a patient sample with extension products of the primer, characterizing the extension products, and comparing the extension products with known nucleic acid sequences of various genotypes for determining the genotype of the nucleic acid sequence extended. In the assay, at least one primer or the dNTPs is labeled.Type: GrantFiled: February 13, 2001Date of Patent: November 2, 2004Assignee: Canadian Blood ServicesInventor: Yu-Wen Hu
