Patent number: 9685402Abstract: A semiconductor device has a semiconductor die with composite bump structures over a surface of the semiconductor die. A conductive layer is formed over the substrate. The conductive layer has a channel in an interconnect site of the conductive layer. The channel extends beyond a footprint of the composite bump structures. The semiconductor die is disposed over the substrate. The bump material of the composite bump structures is melted. The composite bump structures are pressed over the interconnect site of the conductive layer so that the melted bump material flows into the channel. Electrical continuity between the composite bump structures and conductive layer is detected by a presence of the bump material in the channel. No electrical continuity between the composite bump structures and conductive layer is detected by an absence of the bump material in the channel. The electrical continuity can be detected by visual inspection or X-ray.Type: GrantFiled: December 13, 2011Date of Patent: June 20, 2017Assignee: STATS ChipPAC Pte. Ltd.Inventors: Jen Yu Chen, Chien Chen Lee, Yi Wen Huang, Ke Jung Jen

Patent number: 9263941Abstract: A resonant converter with power factor correction includes a power-obtaining circuit, an energy-storage element and an energy-transferred circuit. The power-obtaining circuit is used for receiving an input line voltage. The energy-storage element is coupled between the power-obtaining circuit and the energy-transferred circuit. The energy-transferred circuit is used for generating an output power. In a first time period, based on a first control signal, the energy-storage element and the power-obtaining circuit operate a soft switching so that the energy-storage element is charged to obtain the input line power and generate an energy-storage voltage. In a second time period, based on a second control signal, the energy-storage element and the energy-transferred circuit operate a soft switching so that the energy-storage element is discharged to make the energy-storage voltage converted into the output power.Type: GrantFiled: October 2, 2012Date of Patent: February 16, 2016Assignee: MACROBLOCK, INC.Inventors: Lon-Kou Chang, Yi-Wen Huang, Han-Hsiang Huang
