  • Patent number: 6828682
    Abstract: A substrate that includes a non-electrically conductive core having a first side and an opposing second side. A first electrically conductive layer is disposed on the first side of the core, and a second electrically conductive layer is disposed on the second side of the core. Electrically conductive core vias extend from the first side of the core to the second side of the core. The core vias are disposed in an array. An electrically conductive contact is formed on an upper build-up layer on the first side of the core, and overlies the array of core vias. A first electrically conductive via electrically connects the contact to an intervening build-up layer disposed between the upper build-up layer and the first electrically conductive layer. The first via overlies the core via array. A second electrically conductive via electrically connects the intervening build-up layer and the first electrically conductive layer, where the second electrically conductive via is not disposed over the core via array.

  • Publication number: 20040241554
    Abstract: The mask includes a substrate formed of a material having a first index of refraction and a first level of transmittance to a wavelength of light with which the phase shift mask is designed for use. Second portions of the substrate are impregnated with a dopant species, leaving first portions of the substrate unaffected by the dopant species. The second portions of the substrate have a second index of refraction and a second level of transmittance to the wavelength of light. The first index of refraction is not equal to the second index of refraction. The second portions of the substrate shift a phase of the light relative to the first portions of the substrate and thereby increase an effective imaging resolution of the phase shift mask. In this manner, instead of using an etch process or a deposition process to form phase shifting regions of the mask, a doping processing is used instead. Most preferably, an ion implantation process is used.

  • Patent number: 6825546
    Abstract: A varactor is formed with a semiconductor junction having a retrograde dopant concentration profile in a depletion region.

  • Patent number: 6825554
    Abstract: A method for fabricating a semiconductor package having a 2-layer substrate, which includes an array of solder balls, is disclosed. The method includes patterning signal traces on a top layer of the substrate and identifying groups of signal traces to isolate. According to the present invention, a grounded isolation trace is then patterned adjacent to one of the groups of traces to isolate the signal traces, thereby providing noise shielding. In a preferred embodiment, the grounded isolation trace is provided with multiple vias, rather than only one. In a further aspect of the present invention a row of solder balls is connected together and to ground to create a bottom-layer isolating ground trace to further reduce noise. The bottom-layer isolating ground trace may be connected to the top-layer isolating ground trace using a via.

  • Patent number: 6825066
    Abstract: A stiffener for reinforcing a package integrated circuit. The stiffener includes a rigid planar element having a first surface for bonding to a package substrate. The rigid planar element forms a major interior aperture for receiving and surrounding an integrated circuit on all sides of the integrated circuit. The rigid planar element also forms a minor interior aperture for receiving and surrounding a secondary circuit structure on at least three sides of the secondary circuit structure. In this manner, the stiffener provides structural support to the integrated circuit package, which reduces and preferably eliminates twisting and warping of the substrate package as it heats and is subjected to other stresses.

  • Patent number: 6823487
    Abstract: An improved error correction code process takes advantage of information available from a post processor. This information is a list of highly probable error event patterns and locations found by employing a list Viterbi or a set of matched filters on Viterbi data. This list of possible errors can be used by the error correction code decoder in an iterative process whenever the correction power of the error correction code decoder is exceeded. If the error correction code decoder cannot correct the data on its first unassisted try, an iterative process is employed which, in essence, modifies the data with potential errors identified from the list created by the post processor and tries the correction process over again. An algorithm may be employed to try each error singly or in combination with other errors. This iterative process continues until a correctable indication is given by the error correction code decoder algorithm.
