Abstract
Producing a joint between metal surfaces such as, for example, workpiece and solder or two workpieces, comprises providing chemically active gas radicals or ions so that before or during the joining process they spread over at least one of the metal surfaces. Also claimed is an apparatus for implementation of the proposed method. USE - In manufacture of high-power semiconductor devices. ADVANTAGE - Faults (uniform heat transfer, poor mechanical performance) in such devices produced by known practices are eliminated.
