摘要： Methods of forming a conductive metal layers on substrates are disclosed which employ a seed layer to enhance bonding, especially to smooth, low-roughness or hydrophobic substrates. In one aspect of the invention, the seed layer can be formed by applying nanoparticles onto a surface of the substrate; and the metallization is achieved by electroplating an electrically conducting metal onto the seed layer, whereby the nanoparticles serve as nucleation sites for metal deposition. In another approach, the seed layer can be formed by a self-assembling linker material, such as a sulfur-containing silane material.

摘要： 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.

摘要： 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.
