Abstract: An electrode for a lithium-ion battery (100) of the present invention includes a collector layer (101) and an electrode active material layer (103) which is provided on at least one surface of the collector layer (101) and includes an electrode active material, a binder resin, and a conductive auxiliary agent, and an interface resistance between the collector layer (101) and the electrode active material layer (103), which is measured at a normal pressure by bringing an electrode probe into contact with a surface of the electrode active material layer (103), is more than 0.0010 ?·cm2 and less than 0.10 ?·cm2.

Abstract: The semiconductor device includes an interconnect having a width of 0.1 ?m or less and formed in an insulating layer constituted of a low relative dielectric constant film having a relative dielectric constant of 3.0 or lower, a via having a diameter of 0.1 ?m or less and connected to the interconnect, and a dummy metal provided in the insulating layer. The dummy metal is located close to an end portion of the interconnect along an extension thereof, and the dummy metal and the interconnect are spaced by a distance of 0.3 ?m or less.

Abstract: A semiconductor device includes an insulating interlayer formed above a silicon substrate and provided with a concave portion in a certain location, a barrier metal film covering an inner wall of the insulating interlayer, a lower layer copper interconnect provided so as to be in contact with the barrier metal film and buried in the interior of the concave portion, and a protective film provided so as to be in contact with the lower layer copper interconnect and also provided on substantially the entire top surface of the lower layer copper interconnect. An upper surface of the lower layer copper interconnect is provided so as to be retracted to be closer to the substrate than an upper surface of barrier metal film on the side wall of the concave portion.
