Abstract
【解決手段】金属層の第1の面を第1の絶縁層で被覆し、金属層の第2の反対側の面を第2の絶縁層で被覆する。第2の反対側の面上の第2の絶縁層の残存部分が、第1の面上の接合位置の真反対側に配置されるように金属層の第1の面に接合位置を露出させるために第1の絶縁層をパターン形成し、第2の絶縁層をパターン形成する。分離された同一平面上の金属層を形成するために第2の反対側の面上で第2の絶縁層の残存部分によって覆われない金属層の部分を選択的に除去する。分離された同一平面上の金属層は接合位置を含む。第2の絶縁層の残存部分を選択的に除去し、これにより分離された同一平面上の金属層の第2の反対側の面上に第2の接合位置を露出させる。
