The leads (9) and the semiconductor chip (10) are electrically connected and are covered with a sealing resin (8). A concave portion (7e) is formed on the outer side of each lead (9), i.e., the far side from the die pad. A lead concave surface (7d) facing the concave portion (7e) includes a forward-tapered lead slope surface (7h). Side surface of the sealing resin (8) has a step of a staircase shape formed from the first and the second resin side surfaces (8a and 8b). A tip of the lead (9) protrudes past the first resin side surface (8a)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and method of manufacturing the semiconductor device","description":"In a semiconductor device (4), a semiconductor chip (10) is mounted on a die pad (6) which has a die pad overhang portion (6a) and leads (9) are arranged around and apart from the die pad (6).
