A protection layer is formed on a substrate, such that bond pads of the substrate are respectively exposed form protection layer openings of the protection layer. A conductive layer is formed on the bond pads and the protection layer. A patterned first photoresist layer is formed on the conductive layer. Copper bumps are respectively formed on the conductive layer located in the first photoresist layer openings. A patterned second photoresist layer is formed on the first photoresist layer, such that at least one of the copper bumps is exposed through second photoresist layer opening and the corresponding first photoresist layer opening. A diffusion barrier layer and an oxidation barrier layer are formed on the copper bump. The first and second photoresist layers, and the conductive layer not covered by the copper bumps are removed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inductor structure and manufacturing method thereof","description":"A manufacturing method of an inductor structure includes the following steps.
