First lead fingers that project from the connection bar towards the die pad have proximal ends close to the die pad and distal ends connected to the connection bar. The proximal ends of the first lead fingers lie in a first plane. Second lead fingers that project from the connection bar towards the die pad have proximal ends close to the die pad and distal ends connected to the connection bar. The proximal ends of the second lead fingers lie in a second plane that is parallel and spaced from the first plane. An isolation frame is disposed between the proximal ends of the first and second lead fingers. The isolation frame separates but supports the proximal ends of the first and second lead fingers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lead frame for semiconductor device","description":"A lead frame for a semiconductor device has a die pad with a first major surface for receiving an semiconductor die and a connection bar that encircles the die pad.
