STRUCTURE AND METHOD FOR STABILIZING LEADS IN WIRE-BONDED SEMICONDUCTOR DEVICES
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.
SEMICONDUCTOR MODULE COMPRISING A SEMICONDUCTOR AND COMPRISING A SHAPED METAL BODY THAT IS ELECTRICALLY CONTACTED BY THE SEMICONDUCTOR
Semiconductor module including a semiconductor and including a shaped metal body that is electrically contacted by the semiconductor, for forming a contact surface for an electrical conductor, wherein the shaped metal body is bent or folded. A method is also described for establishing electrical contacting of an electrical conductor on a semiconductor, said method including the steps of: fastening a bent or folded shaped metal body of a constant thickness to the semiconductor by means of a first fastening method and then fastening the electrical conductor to the shaped metal body by means of a second fastening method.
WIRING SYSTEM
A method for attaching a prefabricated miniature coaxial wire to a first electrical connection point, the prefabricated miniature coaxial wire having an electrically conductive core disposed within an electrical insulation layer disposed within an electrically conductive shield layer, includes attaching an exposed portion of the electrically conductive core at a distal end of the prefabricated miniature coaxial wire to the first electrical connection point, thereby establishing electrical conductivity between the electrically conductive core and the first electrical connection point, depositing a layer of electrically insulating material onto the exposed portion of the electrically conductive core such that the exposed portion of the electrically conductive core and the first electrical connection point is encased in the layer of electrically insulating material, and connecting the electrically conductive shield layer to a second electrical connection point using a connector formed from an electrically conductive material.
