  • Publication number: 20230369284
    Abstract: A method for forming a contact connection between a chip-and a conductor material formed on a non-conductive substrate, the chip being arranged on the substrate or on another conductor material track, a sinter paste consisting of at least 40% silver or copper being applied to respective chip contact surfaces of the chip and the conductor material track, a contact conductor being immersed in the sinter paste on the chip contact surface and in the sinter paste on the conductor material track, and the contact connection being formed by sintering the sinter paste by means of laser energy.

  • Patent number: 10354971
    Abstract: The invention concerns a method for producing a chip module having a carrier substrate and at least one chip arranged on the carrier substrate, as well as a contact conductor arrangement for connecting chip pads to contacts arranged on a contact face of the chip module, in which method the front face of the chip which is provided with the chip pads is secured to the carrier substrate and then the contact conductor arrangement is formed by structuring of a contact material layer of the carrier substrate.

  • Publication number: 20180047697
    Abstract: The invention relates to a chip arrangement (10) and to a method for forming a contact connection (11) between a chip (18), in particular a power transistor or the like, and a conductor material track (14), the conductor material track being formed on a non-conductive substrate (12), the chip being arranged on the substrate or on a conductor material track (15), a silver paste (29) or a copper paste being applied to each of a chip contact surface (25) of the chip and the conductor material track (28), a contact conductor (30) being immersed into the silver paste or the copper paste on the chip contact surface and into the silver paste or the copper paste on the conductor material track, a solvent contained in the silver paste or the copper paste being at least partially vaporized by heating and the contact connection being formed by sintering the silver paste or the copper paste by means of laser energy.
