  • Publication number: 20140061928
    Abstract: An interconnection structure for being formed on bonding pads of a substrate in a semiconductor package is provided. The interconnection structure includes a nickel layer formed on each of the bonding pads, a metal layer formed on the nickel layer, and a solder material formed on the metal layer. The metal layer is made of one of gold, silver, lead and copper, and has a thickness in the range of 0.5 to 5 um. As such, when the solder material is reflowed to form solder bumps, no nickel-tin compound is formed between the solder bumps and the metal layer, thereby avoiding cracking or delamination of the solder bumps.

  • Patent number: 8194146
    Abstract: An apparatus for capturing and storing real-time images is provided. A camera module records frames corresponding to sensed light, outputs pixel data of the frames on a data bus, and generates synchronization control signals to control the synchronized transmission of the frames. An interrupt controller receives the synchronization control signals and correspondingly generates interrupt signals. A processing unit receives the interrupt signals, fetches the pixel data of the frames on the data bus according to at least one of the interrupt signals, and stores the fetched pixel data in a memory device.
