Abstract:
A conditioner for a polishing pad used for flat polishing processes for semiconductor substrates, wherein diamond grains are supported by monolayer brazing in/on a supporting material comprising a metal and/or alloy, using an alloy with a melting point of 600-1200.degree. C. which consists essentially of 0.5-20% by weight of at least one metal selected from the group consisting of titanium, zirconium and chromium and 30-99.5% by weight of at least one metal selected from the group consisting of gold, platinum and silver, said alloy with the melting point of 600-1200.degree. C. having an improved corrosion resistance compared to nickel electrodeposition with respect to an acidic slurry.
