  • Publication number: 20140131841
    Abstract: Various embodiments of mechanisms for forming a slotted metal pad over a TSV in substrate are provided. The dielectric structures in the slotted metal pad reduce dishing effect during planarization of the slotted metal pad.

  • Publication number: 20140090882
    Abstract: One or more techniques or systems for mitigating peeling associated with a pad, such as a pad of a semiconductor, are provided herein. In some embodiments, a pad structure for mitigating peeling comprises a bond region located above a first region. In some embodiments, a first inter-layer dielectric region associated with the first region is formed in an inter-layer region under the pad. Additionally, a first inter-metal dielectric region associated with the first region is formed in an inter-metal region under the inter-layer region. In some embodiments, the first inter-metal region is formed under the first inter-layer region. In this manner, peeling associated with the pad structure is mitigated, at least because the first inter-metal dielectric region comprises dielectric material and the first inter-layer dielectric region comprises dielectric material, thus forming a dielectric-dielectric interface between the first inter-metal dielectric region and the inter-layer dielectric region.

  • Patent number: 8152143
    Abstract: An improved structure of cooling tower includes a fan housing with a fan disposed therein, induction openings distributed on the fan housing and located below the fan, and a diffuser stack disposed at one end surface of the fan housing. In operation, cold air is drawn into the cooling tower by the fan through inlet openings of the cooling tower so as to exchange heat with the condensing water within a water chiller. When warm and wet air is drawn out of the cooling tower and the warm and wet air outside the cooling tower is induced in through the induction openings and then is drawn out, circulation reflux of warm and wet air, which tends to occur in conventional cooling towers, can be avoided and therefore increase the efficiency of the water chiller.

  • Patent number: 7498653
    Abstract: A semiconductor structure for isolating a first circuit and a second circuit of various operating voltages includes a first isolation ring surrounding the first and second circuits on a semiconductor substrate. A buried layer continuously extending underneath the first and second circuits is formed on the semiconductor substrate, wherein the buried layer interfaces with the first isolation ring for isolating the first and second circuits from a backside bias of the semiconductor substrate. An ion enhanced isolation layer is interposed between the buried layer and well regions on which devices of the first and second circuits are formed, wherein the ion enhanced isolation layer is doped with impurities of a polarity type different from that of the buried layer.

  • Publication number: 20080175705
    Abstract: An anti-vibration fan includes a frame, a bottom chassis and an elastic frame. The elastic frame includes a plurality of curved plate-like suspending arms, each having a first suspending arm section. An end of the suspending arm section has a bent section with a curved shape at its middle section, and an end of the bent section has a second suspending arm section. The bottom chassis includes a disc body and a plurality of protruding ribs extended upward from the disc body and connected to the first suspending arm section. The second suspending arm section is connected to a frame body of the frame, and the plurality of suspending arms form the elastic frame. After vanes are pivotally connected to the bottom chassis, the elastic frame cancels out the vibration force produced by the rotating vanes, so as to reduce noises and enhance the life expectancy of vanes effectively.

  • Patent number: 7301185
    Abstract: A high-voltage transistor device with an interlayer dielectric (ILD) etch stop layer for use in a subsequent contact hole process is provided. The etch stop layer is a high-resistivity film having a resistivity greater than 10 ohm-cm, thus leakage is prevented and breakdown voltage is improved when driving a high voltage greater than 5V at the gate site. A method for fabricating the high-voltage device is compatible with current low-voltage device processes and middle-voltage device processes.
