Packaging conductive structure for a semiconductor substrate having a metallic layer
Abstract:
A packaging conductive structure for a semiconductor substrate and a method for forming the structure are provided. The dielectric layer of the packaging conductive structure partially overlays the metallic layer of the semiconductor substrate and has a receiving space. The lifting layer and conductive layer are formed in the receiving space, wherein the conductive layer extends for connection to a bump. The lifting layer is partially connected to the dielectric layer. As a result, the conductive layer can be stably deposited on the edge of the dielectric layer for enhancing the reliability of the packaging conductive structure.
