  • Publication number: 20060196765
    Abstract: A method for forming a microelectronic layer while employing a sputtering method employs a reactor chamber. A sputtering target and a substrate are positioned within the reactor chamber, along with a sputtering target heater at a side of sputtering target opposite the substrate. At least one of: (1) a heater to sputtering target distance; (2) sputtering power; (3) deposition time; and (4) sputtering gas flow rate, is controlled in accord with a pre-determined function of sputtering target lifetime to provide enhanced uniformity of the deposited layer.

  • Patent number: 7030016
    Abstract: A method of forming a copper interconnect in a dual damascene scheme is described. After a diffusion barrier layer and seed layer are sequentially formed on the sidewalls and bottoms of a trench and via in a dielectric layer, a first copper layer is deposited by a first ECP process at a 10 mA/cm2 current density to fill the via and part of the trench. A first anneal step is performed to remove carbon impurities and optionally includes a H2 plasma treatment. A second ECP process with a first deposition step at a 40 mA/cm2 current density and second deposition step at a 60 mA/cm2 current density is used to deposit a second copper layer-that overfills the trench. After a second anneal step, a CMP process planarizes the copper layers. Fewer copper defects, reduced S, Cl, and C impurities, and improved Rc performance are achieved by this method.

  • Publication number: 20060000717
    Abstract: A method of stabilizing plating film impurities in an electrochemical plating bath solution is disclosed. The method includes providing an electrochemical plating machine in which an electrochemical plating process is carried out. A by-product bath solution is formed by continually removing a pre-filtered bath solution from the machine and removing an additive from the pre-filtered bath solution. A clean bath solution is formed by removing an additive by-product from the by-product bath solution. An additive bath solution is formed by adding a fresh additive to the clean bath solution. The additive bath solution is added to the electrochemical plating machine. An apparatus for stabilizing film impurities in an electrochemical plating bath solution is also disclosed.

  • Publication number: 20050245064
    Abstract: A novel method for preventing the formation of voids in metal interconnects fabricated on a wafer, particularly during a thermal anneal process, is disclosed. The method includes fabricating metal interconnects between metal lines on a wafer. During a thermal anneal process carried out to reduce electrical resistance of the interconnects, the wafer is positioned in spaced-apart relationship to a wafer heater. This spacing configuration facilitates enhanced stabilility and uniformity in heating of the wafer by reducing the presence of particles on and providing a uniform flow of heated air or gas against and the wafer backside. This eliminates or at least substantially reduces the formation of voids in the interconnects during the anneal process.

  • Publication number: 20050239221
    Abstract: A method for monitoring copper film quality and for evaluating the annealing efficiency of a copper annealing process includes measuring hardness of a copper film formed on a substrate before and after annealing and comparing the hardness measurement results. The measurements can be correlated to grain boundary saturation levels, copper grain sizes and therefore conductivity. Hardness measurements may be taken at a plurality of locations throughout the substrate to account for variations in the copper film grain structure.

  • Publication number: 20050085066
    Abstract: A method of forming a copper interconnect in an opening within a pattern is described. The copper interconnect has an Rs that is nearly independent of opening width and pattern density. A first copper layer having a concave upper surface and thickness t1 is formed in a via or trench in a dielectric layer by depositing copper and performing a first CMP step. A second copper layer with a thickness t2 where t2?t1 and having a convex lower surface is deposited on the first copper layer by a selective electroplating method. The first and second copper layers are annealed and then a second CMP step planarizes the second copper layer to become coplanar with the dielectric layer. The invention is also a copper interconnect comprised of the aforementioned copper layers where the first copper layer has a grain density (GD1)?GD2 for the second copper layer.

  • Publication number: 20040061715
    Abstract: An organizational system that can organize all of the parts associated with a given system down to a nth or least/lowest replaceable/repairable component in a hierarchical manner and store the parts as a Bill of Materials (BOM). Each of the different parts listed in the BOM is associated with a unique part number. The organizational system can display or print the BOM such that the hierarchy between the parts is apparent so that the BOM can be used to build actual systems (assemblies).

  • Patent number: 6647019
    Abstract: A packet-switch system utilizes a linecard-to-switch (LCS) protocol to integrate linecards with a switch core. Since the linecards include a majority of the buffering of the system and are located physically away from switch core, the size of the switch core can be reduced in size. The LCS protocol is a label-swapping, credit-based, flow-control, which enables the system to operate without requiring such information as the number of port modules available within a switch core or what Qualities of Service (QoS) or multicast flows are available. In addition, the LCS protocol enables the linecards to contain and manage the majority of the buffers in the system, and also to control the data drop policy within the system.

  • Patent number: 6389475
    Abstract: The invention provides a method and system for content-based filtering of multicast information. A set of sources (S) which desire to distribute potentially large numbers of categories of differing information each associates a content descriptor (CD) with messages including information in those categories, so that a set of recipients (R) can receive information in at least some of those categories. A mapping server (M) associates a multicast address (MA) and a content mask (CM) with each content descriptor, so that network elements (N), such as routers, in the network can distribute only those messages which are of interest to recipients in multicast distribution trees for those multicast addresses. Each source generates content descriptors for each differentiable topic in a tree structured hierarchy, and obtains a multicast address and a content mask for the broadest content descriptor it is capable of distributing.

  • Patent number: 6325283
    Abstract: The NYTBridge allows a user to bridge the gap between data collected by hand-held scanning devices and conventional databases used in the field of inventory management without database or procedural programming knowledge on the part of the user. The NYTBridge does this by first allowing the user to access an existing database. The user may then select data fields, such as the location of an item in inventory, from the database without writing coded database queries. The NYTBridge then allows the user to download the selected data fields as a data set along with a scanner program that will read the created data set. Both the data set and the scanner program are either saved on a PCMCIA card to be used in a scanner, or downloaded directly into the hand held scanner via either serial port communication or communication dock tethering. When the scanner program is run on the scanner, the scanner program creates a scanner file for the collected, verified and/or corrected data.
