  • Patent number: 7153589
    Abstract: A Mo—W material for the formation of wirings is discloses which, as viewed integrally, comprises 20 to 95% of tungsten and the balance of molybdenum and inevitable impurities by atomic percentage. The Mo—W material for wirings is a product obtained by compounding and integrating a Mo material and a W material as by the powder metallurgy technique or the smelting technique or a product obtained by arranging these materials in amounts calculated to account for the percentage composition mentioned above. The Mo—W material containing W in a proportion in the range of from 20 to 95% manifests low resistance and, at the same time, excels in workability and tolerance for etchants. The wiring thin film which is formed of the Mo—W alloy of this percentage composition is used as address wirings and others for liquid crystal display devices.

  • Patent number: 6976889
    Abstract: In a method of connecting a terminal with a wire in which a core (2) of a wire is inserted into a tubular wire connecting portion (1) of a terminal, and the wire connecting portion is crimped in a radial direction of the wire, the wire connecting portion is compressed in a radial direction of the wire and uniformly over the whole circumference. While rotating dies (7?) by using a rotary swaging machine, the wire connecting portion is compressed by the dies in a radial direction of the wire and uniformly over the whole circumference. The wire connecting portion is compressed in a radial direction of the wire and uniformly over the whole circumference, and the outer periphery of a compressed part of the wire connecting portion has a true circular section shape.

  • Patent number: 6625884
    Abstract: A method of determining whether a metal terminal including a conductor clamping section for clamping a wire is satisfactorily connected to the wire. First, a first metal terminal including a first conductor clamping section for clamping a first wire thereto is provided. Next, one of a dimensional variation and a ratio of a dimensional change of the first conductor clamping section in an axial direction of the first metal terminal, which are caused by clamping the first conductor clamping section, is calculated. Compressibility comparison data is prepared by calculating, from a section of the first conductor clamping section after clamping the first conductor clamping section, compressibility of the first wire with respect to the first conductor clamping section based on the one of the dimensional variation and the ratio of the dimensional change.

  • Patent number: 6352628
    Abstract: A refractory metal silicide target is characterized by comprising a fine mixed structure composed of MSi2 (where M: refractory metal) grains and Si grains, wherein the number of MSi2 grains independently existing in a cross section of 0.01 mm2 of the mixed structure is not greater than 15, the MSi2 grains have an average grain size not greater than 10 &mgr;m, whereas free Si grains existing in gaps of the MSi2 grains have a maximum grain size not greater than 20 &mgr;m. The target has a high density, high purity fine mixed structure with a uniform composition and contains a small amount of impurities such as oxygen etc. The employment of the target can reduce particles produced in sputtering, the change of a film resistance in a wafer and the impurities in a film and improve yield and reliability when semiconductors are manufactured.

  • Patent number: RE41975
    Abstract: An interconnector line of thin film comprising 0.001 to 30 at % of at least one kind of a first element capable of constituting an intermetallic compound of aluminum and/or having a higher standard electrode potential than aluminum, for example, at least one kind of the first element selected from Y, Sc, La, Ce, Nd, Sm, Gd, Tb, Dy, Er, Th, Sr, Ti, Zr, V, Nb, Ta, Cr, Mo, W, Mn, Tc, Re, Fe, Co, Ni, Pd, Ir, Pt, Cu, Ag, Au, Cd, Si, Pb and B; and one kind of a second element selected from C, O, N and H in a proportion of 0.01 at ppm to 50 at % of the first element, with the balance comprising substantially Al. In addition to having low resistance, such an Al interconnector line of thin film can prevent the occurrence of hillocks and the electrochemical reaction with an ITO electrode. The interconnector line of thin film can be obtained by sputtering in a dust-free manner by using a sputter target having a similar composition.
