  • Patent number: 7968446
    Abstract: The metallic bump is directly formed on a semiconductor wafer's I/O pad without UBM. First, a zinc layer is formed on the I/O pad or an anti-oxidation layer of the I/O pad is selectively etched off. Then, an isolative layer and a copper foil are arranged sequentially in this order above the I/O pad. The isolative layer is originally in a liquid state or in a temporarily solid state and later permanently solidified. Then, a via above the I/O pad is formed by removing part of the isolative layer and the cooper foil. Subsequently, A thin metallic layer connecting the copper foil and the I/O pad is formed in the via and a plating resist on the copper foil is formed. Then, a metallic bump is formed from the via whose height is controlled by the plating resist. Finally, the plating resist and the copper foil are removed.

    Abstract: A system in package (10) has a, preferably wireless, test controller (20) for testing each die (30) after it has been mounted onto the substrate of the system in package (10), and a faulty die (30) is repaired before a next die (30) is mounted onto the substrate (15). This way, the system in package (10) can be tested during the intermediate stages of its manufacturing, thus ensuring that all dies (30) function correctly before sealing the dies in the single package. Consequently, a method for manufacturing a system in package (10) is obtained that has an improved yield compared to known manufacturing methods.

  • Patent number: 7955969
    Abstract: Processes are described for forming very thin semiconductor die (1 to 10 microns thick) in which a thin layer of the upper surface of the wafer is processed with junction patterns and contacts while the wafer bulk is intact. The top surface is then contacted by a rigid wafer carrier and the bulk wafer is then ground/etched to an etch stop layer at the bottom of the thin wafer. A thick bottom contact is then applied to the bottom surface and the top wafer carrier is removed. All three contacts of a MOSFET may be formed on the top surface in one embodiment or defined by the patterning of the bottom metal contact.

  • Patent number: 7952377
    Abstract: Improved probing of closely spaced contact pads is provided by an array of vertical probes having all of the probe tips aligned along a single contact line, while the probe bases are arranged in an array having two or more rows parallel to the contact line. With this arrangement of probes, the probe base thickness can be made greater than the contact pad spacing along the contact line, thereby advantageously increasing the lateral stiffness of the probes. The probe tip thickness is less than the contact pad spacing, so probes suitable for practicing the invention have a wide base section and a narrow tip section.
