  • Publication number: 20170323865
    Abstract: A chip arrangement including a chip comprising a chip back side; a back side metallization on the chip back side, the back side metallization including a plurality of layers; a substrate comprising a surface with a metal layer; a zinc-based solder alloy configured to attach the back side metallization to the metal layer, the zinc-based solder alloy having by weight 8% to 20% aluminum, 0.5% to 20% magnesium, 0.5% to 20% gallium, and the balance zinc; wherein the metal layer is configured to provide a good wettability of the zinc-based solder alloy on the surface of the substrate. The plurality of layers may include one or more of a contact layer configured to contact a semiconductor material of the chip back side; a barrier layer; a solder reaction, and an oxidation protection layer configured to prevent oxidation of the solder reaction layer.
