The method also includes forming a magnetic film on a top surface of the protect layer and a top surface of the substrate in at least one opening formed in the seed layer and the protect layer. The method further includes forming at least one patterned magnetic feature on the top surface of the substrate by electro-etching the magnetic film, wherein the seed layer provides a self-stop for the electro-etching of the magnetic film."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Patterning magnetic films using self-stop electro-etching","description":"A method of forming a semiconductor structure includes forming a seed layer over a top surface of a substrate and a protect layer over a top surface of the seed layer.
