METAL PLATING ADDITIVE, AND METHOD FOR PLATING SUBSTRATES AND PRODUCTS THEREFROM |
摘要 |
<p>The present invention is directed to the fabrication of rigid memory disks, including a metal plating composition which impedes deposition of non-metallic particles during a plating process. The plating composition includes at least one sulfated fatty acid ester additive, or mixtures or salts thereof, of formula : wherein R1 is selected from the group consisting of OH, OCH2, OCH2CH3, C1-C7 alkyl, linear or branched; R2 selected from H and C1-C7 alkyl, linear or branched; m= 1 to about 5; n = 2 to about 30; o = 0 to about 10; M+ is a metal or pseudo metal ion or H+. The additive has a zeta potential which impedes deposit of non-metallic particles. The invention is further directed to a method for electroless plating utilizing the additive composition in a bath with at least a stabilizing agent, complexing agent and reducing agent and source of metal ions.</p> |
