Abstract:
1. A bond pad structure, comprising: an upper conductive layer embedded in a dielectric layer; a first passivation layer, wherein the first passivation layer covers a portion of the upper conductive layer and exposes the upper conductive layer via a first opening, wherein the first passivation layer is a single continuous layer and is in direct contact with the dielectric layer; a bond pad, wherein the bond pad covers a portion of the first passivation layer, and wherein the bond pad fills the first opening in the first passivation layer to form a first ring recess and a second ring recess spaced from the first ring recess, and at least one of the first ring recess region or the second ring recess region is a discontinuous ring, and wherein the bond pad comes in contact with the upper conductive layer exposed by the first opening; and a second passivation layer, wherein the second passivation layer covers at least the recess region in the bond pad.
