The preset invention has as its object the provision of a laminate free of hexavalent chromium and excellent in corrosion resistance and wear resistance, and a manufacturing process of the laminate. To solve the above-described problems, a laminate according to the present invention includes a substrate, and a laminated film portion with metal films laminated in two or more layers. The laminate has an interface layer between each two adjacent ones of the metal films. The laminated film portion contains a first metal element as a principal component, the first metal element being at least one element of Ni, Cr, Co, and W, and a second metal element that is a metal element of smaller cohesive energy than that of the first metal element. The second metal element contained in the interface layer is at a content ratio higher than that of the second metal element contained in each of the adjacent metal films.

Provided is an alloy comprising eight or more types of constituent elements, wherein the relative difference in terms of distance between nearest neighbors DNN between a constituent element having the largest distance between nearest neighbors DNN when constituting a bulk crystal from a single element and a constituent element having the smallest distance between nearest neighbors DNN when constituting a bulk crystal from a single element is 9% or less, the number of constituent elements having the same crystal structure when constituting a bulk crystal from a single element is not more than 3, and the difference in concentration between the constituent element having the highest concentration and the constituent element having the lowest concentration is 2 at. % or lower.

Alloy and lithium ion battery

The reliability of wirings, each of which includes a main conductive film containing copper as a primary component, is improved. On an insulating film including the upper surface of a wiring serving as a lower layer wiring, an insulating film formed of a silicon carbonitride film having excellent barrier properties to copper is formed; on the insulating film, an insulating film formed of a silicon carbide film having excellent adhesiveness to a low dielectric constant material film is formed; on the insulating film, an insulating film formed of a low dielectric constant material as an interlayer insulating film is formed; and thereafter a wiring as an upper layer wiring is formed.

Semiconductor device and manufacturing method thereof

A lithium ion secondary battery includes a binder that binds an active material to a current collector in the positive electrode or negative electrodes or both. The binder contains a base material including a resin having a benzene ring, and a polyacene additive selected from the group consisting of naphthalene, anthracene, tetracene, and derivatives thereof. The active material is a carbonaceous material or a lithium-containing composite oxide having a crystal structure in which a distance between nearest oxygen atoms is 0.19 to 0.29 nm. Adhesion of the binder to the active material during the manufacturing of the lithium ion secondary battery is led to a closest-packed crystal plane in the crystal structure of the active material, so that inhibition of moving of lithium ions in and out of the active material due to the binder may be reduced.

Lithium ion secondary battery

A lithium ion secondary battery includes a positive electrode capable of occluding and discharging lithium ions, a negative electrode capable of occluding and discharging the lithium ions, and a nonaqueous electrolyte including a lithium salt, and being reversively charged/discharged. The positive electrode includes a metal plate, a metal film formed on a surface of the metal plate, and a positive electrode active material layer, the metal film includes one or more metals selected from the group consisting of ruthenium, osmium, palladium, and platinum having a orientation, the positive electrode active material layer is a compound expressed by the following expression:LiCoNiO, (where 0&#x2266;&#x2266;1) and is epitaxially grown and formed on a surface of the metal film, and the positive electrode active material is formed such that a c axis of a crystal structure of the positive electrode active material is perpendicular to the metal film.

Provided is a lithium ion battery having a long service life by improving an adhesion strength between a binder resin and a metal foil. A binder resin, which is a compound having a chemical structure that contains a polyvinylidene fluoride molecular chain, a six-membered ring such as a cyclohexane ring, and an end group selected from the group consisting of SiX, SH, NH, GeX, and TiX(wherein X is a functional group that undergoes a condensation reaction), wherein the six-membered ring is disposed in a region between the polyvinylidene fluoride molecular chain and the end group, is mixed with an active material and applied to a metal foil, and the binder resin is chemically bonded to metal atoms such as copper atoms on the surface of the metal foil.

Lithium ion battery and method for producing the same

Manufacturing processes for phase change memory have suffered from the problem of chalcogenide material being susceptible to delamination, since this material exhibits low adhesion to high melting point metals and silicon oxide films. Furthermore, chalcogenide material has low thermal stability and hence tends to sublime during the manufacturing process of phase change memory. According to the present invention, conductive or insulative adhesive layers are formed over and under the chalcogenide material layer to enhance its delamination strength. Further, a protective film made up of a nitride film is formed on the sidewalls of the chalcogenide material layer to prevent sublimation of the chalcogenide material layer.
