  • Patent number: 6265778
    Abstract: A semiconductor device with a multi-level interconnection structure has a first conductive layer disposed below a fuse, and formed in the same layer as the first metal wire as a component of multi-level interconnects, and a second conductive layer disposed below the fuse and formed in the same layer as the second metal wire as a component of the multi-level interconnects. A laser beam control unit is configured with the first and second conductive layers. Thus, damage occurrence in a semiconductor substrate may be controlled during blowing the fuse, a quality deterioration and further a defective of the semiconductor device may be not only avoided, but also an integration degree thereof may be enhanced.

  • Patent number: 6259155
    Abstract: A ceramic column grid array package suitable for mounting application specific integrated circuits or microprocessor chips onto a printed circuit board employing polymer reinforced columns on the substrate module is described. The polymer enhancement is formed by coating a thin conformal film of a polymer, such as, a polyimide onto the substrate module after the formation of the ceramic column grids to mechanically enhance the column to substrate attachment of the column to the substrate prior to mounting on a printed circuit card. Upon curing of the polymer film at a temperature below the melting point of the solder bond attaching the column grid to the substrate, the columns will be mechanically reinforced in their attachment to the substrate. Upon removal of the substrate module from a printed circuit card during rework, the columns of the grid array will remain with the substrate module, leaving no columns on the printed circuit card.

  • Patent number: 6255724
    Abstract: The invention relates to a self-centering arrangement of microstructured elements, particularly of microoptical components on a substrate serving as carrier. To provide microoptical components with projections that fit into corresponding recesses is known in the art. The invention provides a way to improve the mutual alignment of components (K1, K2) in that a deformation occurs when projections (Z1, Z2) are inserted into the recesses (A). This deformation may concern the projections or the recesses themselves or a molding material introduced between the projections and the recesses. The deformation improves the self-centering properties; in addition, manufacturing tolerances are more easily compensated. If the element cannot be provided with a suitable projection, an intermediate carrier is used, which is, for example, a plastic element produced by a LIGA process.

  • Patent number: 6252308
    Abstract: An apparatus and a method for providing a heat sink on an upper surface of a semiconductor chip by placing a heat-dissipating material thereon which forms a portion of a glob top. The apparatus comprises a semiconductor chip attached to and in electrical communication with a substrate. A barrier glob top material is applied to the edges of the semiconductor chip on the surface (“opposing surface”) opposite the surface attached to the substrate to form a wall around a periphery of an opposing surface of the semiconductor chip wherein the barrier glob top material also extends to contact and adhere to the substrate. The wall around the periphery of the opposing surface of the semiconductor chip forms a recess. A heat-dissipating glob top material is disposed within the recess to contact the opposing surface for the semiconductor chip.

  • Patent number: 6229214
    Abstract: According to the present invention, a contact hole is formed by using a contact formation mask until portions of a first and a second impurity areas are respectively exposed, so that contact holes are formed. The size of the contact hole formed over the first impurity area (P-type impurity) is relatively larger than that of the contact hole formed over the second impurity area (N-type impurity). As a result, the size of the contact hole formed over an N-type impurity area decreases and that of the contact hole formed over a P-type impurity area increase to a corresponding degree, thereby reducing contact resistance generated on the P-type impurity area without increasing a chip size.
