A method includes forming a first patterned passivation layer on a workpiece, the first patterned passivation layer having a first opening exposing a conductive feature of the workpiece. A seed layer is formed over the first patterned passivation layer and in the first opening. A patterned mask layer is formed over the seed layer, the patterned mask layer having a second opening exposing the seed layer, the second opening overlapping with the first opening. A connector is formed in the second opening. The patterned mask layer is partially removed, an unremoved portion of the patterned mask layer remaining in the first opening. The seed layer is patterned using the unremoved portion of the patterned mask layer as a mask."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Connector structure and method of forming same","description":"Connector structures and methods of forming the same are provided.
