A semiconductor device includes: a semiconductor substrate; and an electrode including a plurality of layers laminated on a principal surface of the semiconductor substrate. The electrode includes: a first metal layer in contact with the principal surface of the semiconductor substrate, the first metal layer containing Al; an oxide layer formed on a surface of the first metal layer, the oxide layer containing a metal and oxygen; and a second metal layer formed on a surface of the oxide layer. Concentrations of the oxygen in the oxide layer are higher than or equal to 8.0×1021/cm3 and lower than or equal to 4.0×1022/cm3."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and method for manufacturing semiconductor device","description":"An object is to provide a semiconductor device that can prevent organic contamination of an electrode including a plurality of laminated metal layers.
