According to the present invention, there is provided a method of manufacturing a layered structure of wire(s). The method comprises depositing an aluminum alloy containing a lanthanoid on the top surface of a substrate heated to 50� C. to 150� C. both inclusive by sputtering using the alloy as a target wherein the sputtering process is conducted maintaining the substrate and the target under a reduced pressure of 0.18/(M1/2�d) Pa or less in which M is the atomic weight of the target metal and d is a distance between the substrate and the target. The term “atomic weight” as used herein refers to an average atomic weight or the smallest atomic weight in main component metals when a target metal is an alloy. This method allows a number average crystal grain size to be larger than the mean free path of electrons, resulting in providing a layered structure of wire(s) with a reduced resistance. An intervening layer may be present between the substrate and the layered structure of wire(s).
According to the present invention, there is also provided a method of manufacturing a layered structure of wire(s) comprising forming a wiring layer on the top surface of a substrate by sputtering using a low resistance metal containing aluminum, copper or silver as a target and forming a protective layer by sputtering using a refractory metal containing molybdenum as a target such that the protective layer is formed in contact with the wiring layer, wherein the forming the wiring layer and forming the protective layer are conducted under the conditions with a substantially equivalent particle collision parameter represented by P�M1/2�d where P is a sputtering pressure, M is the atomic weight of the target metal or, when the target metal is an alloy, an average in atomic % of the atomic weights of component metals or the smallest atomic weight in main component metals and d is a distance between the substrate and the target. The term “atomic weight” as used herein refers to an average atomic weight or the smallest atomic weight in main component metals when a target metal is an alloy. Substantially equivalent conditions are, for example, those where a particle collision parameter ratio is 0.9 to 1.1 both inclusive.
