The bottom conductive layer is disposed over and electrically connected with the copper layer. The insulating layer is conformally disposed over the bottom conductive layer covering a corner or a downward turning portion of the bottom conductive layer to form a turning portion of the insulating layer. The top conductive layer is conformally disposed over the insulting layer covering the turning portion of the insulating layer.
