  • Patent number: 7279788
    Abstract: A spring contact for establishing electrical contact between a lead element of an IC device and a substrate. The spring contact generally comprises a contact portion and a base portion. The contact portion, which generally comprises a coil-type compression spring, is configured to engage and resiliently bias against a lead element of the IC device. The spring contact is disposed in a mating aperture formed in the substrate. The base portion of the spring contact is configured to secure the spring contact within the mating aperture and to establish electrical contact with the substrate. A plurality of such spring contacts and mating apertures may be arranged on the substrate in an array corresponding to the pin-out of the IC device. A clamping element secures the IC device to the substrate and biases the IC device against the spring contacts.

  • Patent number: 7253514
    Abstract: A connecting element for electrically connecting a semiconductor chip and a superordinate circuit board includes an elastic metal strip that is bent forming two metal limbs with flattened limb ends, thus forming a base between the metal limbs which is suitable for contacting and providing electrical connectivity to a plurality of contact pads of a superordinate circuit board. At least one of the two limb ends is electrically connected to the contact areas of a semiconductor chip, while the other limb end is elastically supported on the top side of the semiconductor chip, thereby enabling the connecting element to be self supporting.

  • Patent number: 7230328
    Abstract: A semiconductor package has a semiconductor device chip and a flexible substrate having a thermoplastic insulating resin layer. An electrode provided on the flexible substrate is connected to a predetermined electrode of the semiconductor device chip and sealed by the thermoplastic insulating resin layer. The flexible substrate is bent and provided with electrodes on the electrode-bearing and other surfaces. The flexible substrate has multi-layered wirings. Grooves or thin layer portions having a different number of wiring layers are formed at bends of the flexible substrate or regions including the bends, thereby creating a cavity at a portion in which a semiconductor device is packaged. Then, the flexible substrate is bent at predetermined positions to form a semiconductor package which does not depend on the outer dimensions of the semiconductor device chip.

  • Patent number: 7205673
    Abstract: A bond pad structure which includes an aluminum bond pad which include one or more dopants that effectively control the growth of IMC to a nominal level in spite of high tensile stresses in the wafer. For example, aluminum can be doped with 1–2 atomic % of Mg. Alternatively, Pd or Si can be used, or elements like Cu or Si can be used as the dopant in order to reduce the overall tensile stresses in the wafer. This can control the abnormal growth of IMC, thus arresting the IMC crack formation. A combination of dopants can be used to both control the tensile stresses and also slightly alter the gold-Aluminum interface thus enabling a uniform and thin IMC formation. This tends to reduce or eliminate any voiding or cracking which would otherwise occur at the wire bond transfer.
