    摘要: The present invention relates to an electrolyte for the electroless deposition of a metal layer on a substrate, wherein the electrolyte is free of heavy metal stabilizers, cyanides, selenium compounds and sulfur compounds comprising sulfur in an oxidation state between −2 and +5, and in which instead a &bgr;-amino acid is used as stabilizer. In particular, the inventive electrolyte can comprise 3-aminopropionic acid, 3-aminobutyric acid, 3-amino-4-methylvaleric acid, and 2-aminoethane-sulfonic acid. Furthermore, the invention is directed to a method for the electroless deposition of metal layers utilizing an inventive electrolyte as well as the use of &bgr;-amino acids as stabilizer in electrolytes for the electroless deposition of metal layers in general.
