    摘要: A system for measuring the size of free air balls for use with a wire bonder having a wire bonding tool and an Electric Flame Off (EFO) device is provided. The system includes an imager disposed above a first image plane, a prism disposed below the imager, and at least one lens positioned between the first image plane and the prism in a first optical path. The at least one lens is positioned between the prism and the imager in a second optical path, where the second optical path is different from the first optical path. An image of the free air ball disposed at a lower portion of the wire bonding tool is provided to the imager via the prism and the at least one lens.

    摘要: A semiconductor wafer has a multi-stage structure that damps and contains nascent cracks generated during dicing and inhibits moisture penetration into the active region of a die. The wafer includes an array of die regions separated by scribe lanes. The die regions include an active region and a first ring that surrounds the active region. A portion of the first ring includes a low-k dielectric material. A second ring includes a stack of alternating layers of metal and interlayer dielectric (ILD) material. A dummy metal region around the rings includes a stacked dummy metal features and surrounds the active region. A regular or irregular staggered arrangement of saw grid process control (SGPC) features reduces mechanical stress during dicing.
