Abstract
Device and method for forming a device are presented. A substrate having circuit component and a back-end-of-line (BEOL) dielectric layer with interconnects is provided. A pad dielectric layer is formed over the BEOL dielectric layer. The pad dielectric layer includes a pad via opening which exposes a surface of one of the interconnects in the BEOL dielectric layer. A pad interconnect is formed on the pad dielectric layer and the pad interconnect is coupled to one of the interconnect in the BEOL dielectric by a pad via contact in the pad via opening. The pad interconnect comprises a pad interconnect pattern which is devoid of 90° angles and any angled structures contained in the pad interconnect pattern less than 90°. A passivation layer is formed on the substrate. The passivation layer lines the pad interconnect and covers an exposed surface of the pad dielectric layer.
