A p-type low-dose region is provided on a front surface of a semiconductor substrate and surrounds a periphery of the sensing effective region. The p-type low-dose region is fixed at an electric potential of a source pad of a main semiconductor element. The p-type low-dose region is disposed to be separated from a p-type base region of the sensing effective region by an n−-type region between the p-type low-dose region and the sensing effective region. A total dose of impurities in the p-type low-dose region is lower than a total dose of impurities in a p-type region of a front side of a semiconductor substrate in a main effective region in which unit cells of the main semiconductor element are disposed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device","description":"A region of a portion directly beneath an OC pad is a sensing effective region in which unit cells of a current sensing portion are disposed.
