By performing etching using a mask layer formed on the insulating layer, a contact hole is formed in the insulating layer to expose a contact region, which is a portion of a main surface of the substrate. The step of forming the contact hole includes a step of providing the contact region with a surface roughness Ra of not less than 0.5 nm. An electrode layer is formed in contact with the contact region. By heating the electrode layer and the substrate, siliciding reaction is caused between the electrode layer and the contact region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for manufacturing silicon carbide semiconductor device","description":"An insulating layer is formed on a substrate made of silicon carbide.
