When a non-magnetic reactive ion etching (RIE) stop layer is used in a damascene main pole fabrication process, the leading edge shield and the side shield have a magnetic separation. By replacing a non-magnetic RIE stop layer with a magnetic RIE stop layer, no removal of the RIE stop layer around the main pole is necessary. Additionally, the leading edge shield and the side shield will magnetically join together without extra processing as there will be no magnetic separation between the leading edge shield and the side shield."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Use of magnetic material for RIE stop layer during damascene main pole formation","description":"A write head for use in a magnetic disk drive and methods of manufacturing the same.
