  • Patent number: 7576002
    Abstract: A method of forming barrier layers in a via hole extending through an inter-level dielectric layer and including a preformed first barrier coated onto the bottom and sidewalls of the via holes. In a single plasma sputter reactor, a first step sputters the wafer rather than the target with high energy ions to remove the barrier layer from the bottom of the via but not from the sidewalls and a second step sputter deposits a second barrier layer, for example of Ta/TaN, onto the via bottom and sidewalls. The two steps may be differentiated by power applied to the target, by chamber pressure, or by wafer bias. The second step may include the simultaneous removal of the first barrier layer from the via bottom and sputter deposition of the second barrier layer onto the via sidewalls.

    Abstract: A wiring metal contains a polycrystal of copper (Cu) as a primary element and an additional element other than Cu, and concentration of the additional element is, at crystal grain boundaries composing the Cu polycrystal and in vicinities of the crystal grain boundaries, higher than that of the inside of the crystal grains. The additional element is preferably at least one element selected from a group consisting of Ti, Zr, Hf, Cr, Co, Al, Sn, Ni, Mg, and Ag. This Cu wiring is formed by forming a Cu polycrystalline film, forming an additional element layer on this Cu film, and diffusing this additional element from the additional element layer into the Cu film.

    Abstract: Different sized features in the array and in the periphery of an integrated circuit are patterned on a substrate in a single step. In particular, a mixed pattern, combining two separately formed patterns, is formed on a single mask layer and then transferred to the underlying substrate. The first of the separately formed patterns is formed by pitch multiplication and the second of the separately formed patterns is formed by conventional photolithography. The first of the separately formed patterns includes lines that are below the resolution of the photolithographic process used to form the second of the separately formed patterns. These lines are made by forming a pattern on photoresist and then etching that pattern into an amorphous carbon layer. Sidewall pacers having widths less than the widths of the un-etched parts of the amorphous carbon are formed on the sidewalls of the amorphous carbon. The amorphous carbon is then removed, leaving behind the sidewall spacers as a mask pattern.

  • Patent number: 7399359
    Abstract: Method and system for generating a metal thin film with a uniform crystalline orientation and a controlled crystalline microstructure are provided. For example, a metal layer is irradicated with a pulsed laser to completely melt the film throughout its entire thickness. The metal layer can then resolidify to form grains with a substantially uniform orientation. The resolidified metal layer can be irradiated with a sequential lateral solidification technique to modify the crystalline microstructure (e.g., create larger grains, single-crystal regions, grain boundary controlled microstructures, etc.) The metal layer can be irradiated by patterning a beam using a mask which includes a first region capable of attenuating the pulsed laser and a second region allowing complete irradiation of sections of the thin film being impinged by the masked laser beam. An inverse dot-patterned mask can be used, the microstructure that may have substantially the same as the geometric pattern as that of the dots of the mask.
