    Abstract: When a photoresist or the like is spin-coated on a semiconductor chip comprising a seal ring is formed, striation due to corners of the seal ring is suppressed. A wiring metal layer and a contact are layered, and a seal structure (28) that surrounds an element forming region (22) on a semiconductor chip (20) is formed. A planar shape of the seal ring structure (28) has shape that is, at a basic level, a rectangle corresponding with the shape of the semiconductor chip (20), but with cutoffs present on corner parts (60) of the rectangle. Specifically, the seal ring structure (28) is disposed along a periphery of a rectangle having corner cutoffs.

  • Patent number: 7508052
    Abstract: A wafer containing a plurality of die separated by streets which are to be sawn has a nitride passivation layer which has openings over die contact locations and gaps leaving nitride strips along the streets. The gaps in the nitride along the streets expose an oxide, preferably TEOS. A nickel/gold plate contact material overlies the nitride layer and contacts the exposed die contact areas but does not adhere to either the nitride surface or the oxide surfaces. A saw blade can then cut along the streets without being gummed by the metalizing and without producing cracks which propagate into the die termination areas.

    Abstract: A wafer test is performed to a wafer, and then a protective film is applied to part of a chip surface of each good chip other than terminals. For defective chips, a protective film is applied to an entire chip surface as well as terminals and, while keeping that state, a burn-in test is performed, thereby cutting off power supply and signal application to defective chips before burn-in test. Moreover, when a chip includes a self-test circuit to judge whether the chip is good or not and the chip is judged to be defective, the function of stopping an internal operation of the chip may be provided or a judgment signal may be transmitted to a burn-in test apparatus, thereby stopping power supply and signal application from the burn-in test apparatus. Thus, power supply and signal application to a chip judged to be defective after burn-in can be cut off.

  • Publication number: 20070241448
    Abstract: Embodiments include electronic assemblies and methods for forming electronic assemblies. One embodiment includes a method of forming a MEMS device assembly, including forming an active MEMS region on a substrate. A plurality of bonding pads electrically coupled to the active MEMS region are formed. A seal ring wetting layer is also formed on the substrate, the seal ring wetting layer surrounding the active MEMS region. A single piece solder preform is positioned on the bonding pads and on the seal ring wetting layer, the single piece solder preform including a seal ring region and a bonding pad region. The seal ring region is connected to the bonding pad region by a plurality of solder bridges. The method also includes heating the single piece solder preform to a temperature above the reflow temperature, so that the bridges split and the solder from the preform accumulates on the seal ring wetting layer and the bonding pads. A lid is coupled to the solder.

  • Patent number: 7151308
    Abstract: A semiconductor chip package includes an interconnection substrate, a central substrate, a peripheral substrate and a semiconductor chip sandwiched between the interconnection substrate and the central substrate. The interconnection substrate has a recessed cavity for receiving the semiconductor chip. The peripheral substrate is separated from the central substrate thereby decreasing the stresses caused by CTE mismatch of the semiconductor chip package. Furthermore, both the central substrate and the peripheral substrate are mechanically and electrically connected to the interconnection substrate such that the semiconductor chip is electrically connected to the peripheral substrate through the central substrate and the interconnection substrate.
