    摘要: A method for forming silicide contacts includes forming a layer on silicon-containing active device regions such as source, drain, and gate regions. The layer contains a metal that is capable of forming one or more metal silicides and a material that is soluble in a first metal silicide but not soluble in a second metal silicide, or is more soluble in the first metal silicide than in the second metal silicide. The layer may be formed by vapor deposition methods such as physical vapor deposition, chemical vapor deposition, evaporation, laser ablation, or other deposition method. A method for forming silicide contacts includes forming a metal layer, then implanting the metal layer and/or underlying silicon layer with a material such as that described above. The material may be implanted in the silicon layer prior to formation of the metal layer. Contacts formed include a first metal silicide and a material that is more soluble in a first metal silicide than in a second metal silicide. The contacts may be part of a semiconductor device including a substrate, active region containing silicon, and silicide contacts disposed over the active region and capable of electrically coupling the active region to other regions such as metallization lines.

    摘要: A method is provided for forming an interconnect in a semiconductor memory device. The method includes forming a pair of source select transistors on a substrate. A source region is formed in the substrate between the pair of source select transistors. A first inter-layer dielectric is formed between the pair of source select transistors. A mask layer is deposited over the pair of source select transistors and the inter-layer dielectric, where the mask layer defines a local interconnect area between the pair of source select transistors having a width less than a distance between the pair of source select transistors. The semiconductor memory device is etched to remove a portion of the first inter-layer dielectric in the local interconnect area, thereby exposing the source region. A metal contact is formed in the local interconnect area.

    摘要: A method of manufacturing an integrated circuit (IC) can utilizes semiconductor substrate configured in accordance with a trench process. The substrate utilizes trenches in a base layer to induce stress in a layer. The substrate can include silicon.

    摘要: A bilayer interlayer dielectric having a spun-on low k gap filled layer is capped with a higher k dielectric layer. Prior to the capping, the spun-on low k dielectric layer is planarized to reduce or eliminate the systematic variation in the relative thickness of the layers due to pattern density effects on the thickness of the spun-on low k dielectric layer. By removing the variations in the relative thickness of the low k dielectric layer and the capping layer, the effective dielectric constant of the uniformly thick composite interlayer dielectric is independent of location on the circuit, preventing differences in circuit speed and the creation of clock skew in the circuit.

    摘要: A method is disclosed for forming completely metallized via holes in semiconductor wafers. Metal pads are formed on one face of a semiconductor wafer together with a conductive interconnecting network. An insulating layer is then deposited to cover this face of the wafer. Holes are etched in the opposite face of the wafer up to and exposing a portion of the metal pads. The via holes are then completely filled with metal by means of electroplating, using the metal pads as a cathode.

    摘要: According to one exemplary embodiment, a two-bit memory cell includes a gate stack situated over a substrate, where the gate stack includes a charge-trapping layer. The charge-trapping layer includes first and second conductive segments and a nitride segment, where the nitride segment is situated between the first and second conductive segments. The nitride segment electrically insulates the first conductive segment from the second conductive segment. The first and second conductive segments provide respective first and second data bit storage locations in the two-bit memory cell. The gate stack can further include a lower oxide segment situated between the substrate and the charge-trapping layer. The gate stack can further include an upper oxide segment situated over the charge-trapping layer. The gate stack can be situated between a first dielectric segment and a second dielectric segment, where the first and second dielectric segments are situated over respective first and second bitlines.
