    Abstract: A lower electrode (4) can have an uneven surface structure. An upper electrode (6) can also have the uneven surface structure. A projecting portion of the upper electrode (6) projecting to the lower electrode side is positioned in a gap between projecting portions of the lower electrode (4) and the lower electrode (4) includes Cu as a main component. Young's moduli of a substrate (1), a stress adjustment layer (2), and the lower electrode (4) have a specific relation. Also, corner portions of radii (R1) of curvature positioned inside a projecting portion (4b) have a specific relation.

    Abstract translation: 下电极(4)可以具有不均匀的表面结构。 上电极(6)也可以具有不平坦的表面结构。 上部电极(6)的突出于下部电极侧的突出部分位于下部电极(4)的突出部分之间的间隙中,下部电极(4)包括Cu作为主要部件。 衬底(1),应力调节层(2)和下电极(4)的杨氏模具具有特定的关系。 此外,位于突出部分(4b)内部的曲率半径(R1)的角部分具有特定的关系。
