  • Structure and method for stabilizing leads in wire-bonded semiconductor devices
    Patent number: 9824959
    Abstract: A semiconductor device having a leadframe including a pad (101) surrounded by elongated leads (110) spaced from the pad by a gap (113) and extending to a frame, the pad and the leads having a first thickness (115) and a first and an opposite and parallel second surface; the leads having a first portion (112) of first thickness near the gap and a second portion (111) of first thickness near the frame, and a zone (114) of reduced second thickness (116) between the first and second portions; the second surface (112a) of the first lead portions is coplanar with the second surface (111a) of the second portions. A semiconductor chip (220) with a terminal is attached the pad. A metallic wire connection (230) from the terminal to an adjacent lead includes a stitch bond (232) attached to the first surface of the lead.
    Type: Grant
