摘要:
The process of the present invention for producing a metal film includes: forming an organic film using a primer composition containing an addition polymerizable compound including three or more reactive groups, an acid group-including addition polymerizable compound, and a hydrophilic functional group-including addition polymerizable compound; forming a metal (M1) salt from the acid group; substituting the metal (M1) salt of the acid group with a metal (M2) salt by processing the organic film with a metal (M2) ion aqueous solution containing a metal (M2) ion having less ionization tendency than the metal (M1) ion; reducing the metal (M2) ion so that a metal film is formed on a surface of the organic film; and oxidizing the metal film. This provides (i) a process for producing a metal film and a metal pattern, at low cost, on an arbitrary substrate, (ii) a metal film, and (iii) use of the meta film.

This invention relates to a method for fabricating high performance chip interconnects and packages by providing methods for depositing a conductive material in cavities of a substrate in a more efficient and time saving manner. This is accomplished by selectively removing portions of a seed layer from a top surface of a substrate and then depositing a conductive material in the cavities of the substrate, where portions of the seed layer remains in the cavities. Another method includes forming an oxide layer on the top surface of the substrate such that the conductive material can be deposited in the cavities without the material being formed on the top surface of the substrate. The present invention also discloses methods for forming multi-level interconnects and the corresponding structures.

Provided is a wear resistant aluminum alloy member. The wear resistant aluminum alloy member of the present invention comprises a substrate comprising an aluminum alloy, and a coated layer coating at least part of a surface of the substrate, and is characterized in that the aluminum alloy has a residual hardness of 120 Hv or more when measured in a room temperature state after held in an atmospheric pressure environment at 400 deg. C for 10 hours; and the coated layer comprises a crystalline Ni-P layer comprising Ni and Ni 3 P. This crystalline Ni-P layer can be obtained by heating a Ni-P plated layer, which has been formed on the surface of the substrate by electroless Ni-P plating, for example, at 300 deg. C or more. Compressive residual stress is imparted to the crystalline Ni-P layer. It is preferred that the aluminum alloy contains 1 to 7 % of Fe because a crystalline Ni-P layer having high adhesion can be obtained.
