  • Patent number: 6140160
    Abstract: A method of forming a MOS device using doped and activated n-type and p-type polysilicon layers wherein a first doped and activated polysilicon layer (either n-type and-p-type) is patterned on a substrate. An isolation material layer is formed abutting the first doped and activated polysilicon layer in the corners formed at the junction between the first doped and activated polysilicon layer and the substrate. A second doped and activated polysilicon layer (either n-type or p-type) is applied over the first doped and activated polysilicon layer and the isolation material layer. The second doped and activated polysilicon layer is planarized to the height of the first doped and activated polysilicon layer. The first and second doped and activated polysilicon layers are etched to substantially bifurcate the first and second doped and activated polysilicon layers. Further processing steps known in the art are utilized to complete the MOS device.

  • Patent number: 6140696
    Abstract: A vertically mountable semiconductor device including a plurality of bond pads disposed proximate to a single edge thereof. The bond pads are bumped with an electrically conductive material. The semiconductor device may also include a support member. Alternatively, the semiconductor device may be laminated to one or more adjacent semiconductor devices. The present invention also includes a method of attaching the semiconductor device to a carrier substrate. Preferably, solder paste is applied to terminals on the carrier substrate. The semiconductor device is oriented vertically over the carrier substrate, such that the bumped bond pads align with their corresponding terminals. The bumps are placed into contact with the solder paste. The bumps and solder paste are then fused to form a joint between each of the bond pads and respective terminal, establishing an electrically conductive connection therebetween and imparting structural stability to the semiconductor device.

  • Patent number: 6140827
    Abstract: A method and apparatus for testing unpackaged semiconductor dice having raised contact locations is disclosed. The apparatus uses a temporary interconnect wafer that is adapted to establish an electrical connection with the raised ball contact locations on the die without damage to the contact location. The interconnect is fabricated on a substrate, such as silicon, where contact members are formed in a pattern that matches the size and spacing of the contact locations on the die to be tested. The contact members on the interconnect wafer are formed as either pits, troughs, or spike contacts. The spike contacts penetrate through the oxide layer formed on the raised ball contact locations contact pad. Conductive traces are provided in both rows and columns and are terminated on the inner edges of the walls of the pits formed in the substrate.

  • Patent number: 6138256
    Abstract: The present invention relates to a system and method for testing one or more semiconductor devices (e.g. packaged chips). Test equipment performs at least tests of a first type on the semiconductor device and identifies failures in the semiconductor device, if any. A number of failures is determined. In the case where there are some failures, decision circuitry determines whether it is more efficient to repeat the tests or repair the semiconductor device, if it is repairable. The semiconductor device may be binned differently depending on the number of identified failures. The decision circuitry may designate the semiconductor device for an additional procedure, if the number of the identified failures is within a first number set. The decision circuitry may designate the semiconductor device for repair, if the number of the identified failures is within a second number set.

  • Patent number: 6136207
    Abstract: A lifting mechanism for a sedimentation tank is provided for vertically raising and lowering a rake assembly in such sedimentation tank. The lifting mechanism comprises one or more elongate members pivotally connected to certain structural elements of the assemblage, such as the rotary drive motor, rake assembly, column or bridge. The pivotal connections of the elongate members are positioned about a horizontal axis and are oriented to receive the torque forces imposed on the assemblage as the rake assembly rotates in the tank simultaneously with vertical lifting. The torque forces are translated into the pivotal connections and are able to counteract those forces to facilitate vertically raising and lowering the rake assembly while it is being rotated in the sedimentation tank.

  • Patent number: RE37158
    Abstract: Implantation of germanium (45) into a PMOS buried channel to permits the enhancement implant profile (to 45) to be made more shallow. The shallow profile will reduce or eventually solve P-channel buried channel-induced short channel effects and enable further decrease in device length to deep submicron range. Benefits include better short channel characteristics, i.e., higher punch through voltage BVDSS, less VT sensitivity to the drain voltage (defined as curl) and better subthreshold leakage characteristics.
