<p>A semiconductor device, for example a power rectifier, formed in a semiconductor body has a contact area coated with a metal layer of, for example, gold. A metallic member is soldered to the layer with an alloy comprising at least 80% lead, the balance being indium and silver in a ratio of at least 4:1 and at most 10:1. One such solder which has good wetting characteristics for improved bond strength contains approximately 92% lead, 7% indium, and 1% silver.</p> |
