  • Patent number: 7476983
    Abstract: In a layout structure of pads and a structure of pad used for a test or wire bonding of a semiconductor device, a size of at least one or more non-wire bonding pads is relatively small as compared with a size of at least one or more pads to be used for wire bonding of the semiconductor device. In the pad structure, a pad includes a wire bonding region that has an embossed surface for a portion of top metal layer within a determined pad size to improve the bonding process, and a probe tip contact region that does not have the embossed surface for a surface portion of the top metal layer within the determined pad size, so as to reduce wear of probe tip during testing of the device. Pad pitch can thereby be increased within a limited region, and peripheral circuits can be further formed in regions that would have been occupied in a conventional pad formation region. Higher integration of semiconductor devices and reduced wear of probe tip in probing is thereby realized.

  • Patent number: 7473580
    Abstract: An improved method for performing an improved Temporary Chip Attach utilizing an Injection Molded Solder (IMS) process to allow efficient testing of die for creating a Known Good Die Bank. The IMS is applied to the testing substrate to form a column on the substrate. The die to be tested can then be attached to the IMS column with C4 solder. A slight reflow is then applied to the die, allowing some of the C4 to melt, and form an electrical connection with the corresponding IMS column. After testing, the die can be removed along with the C4 from the IMS column or permanently attached the substrate by performing a full reflow of the C4.
