Abstract: The present invention relates to the use of ternary nickel-containing metal alloys of the NiMR type (where M=Mo, W, Re or Cr, and R=B or P) deposited by an electroless process in semiconductor technology. In particular, the present invention relates to the use of these deposited ternary nickel-containing metal alloys as barrier material or as selective encapsulation material for preventing the diffusion and electromigration of copper in semiconductor components.
