Abstract
A silicon substrate is restrained from being warped. A substrate is formed by use of a silicon substrate. The substrate has a first surface and a second surface opposite to each other. A metal film is formed over the first surface. An interconnection layer is formed over the second surface. The metal film has a face centered cubic lattice structure. When the metal film is measured by XRD (X-ray diffraction), the [111] orientation intensity A(111), the [220] orientation intensity A(220) and the [311] orientation intensity A(311) of the metal film satisfy the following: A(111)/{A(220)+A(311)}≧10.
