| 摘 要： | 利用一能使化学镀铜过程的阴极和阳极反应分别在不同电极上进行的装置测量了阴、阳极的“短路电流”,并以此电流近似地表示化学镀铜的速度,由“短路电流”随时间的变化推导了化学镀铜过程中阴极区反应物种的表面浓度的变化规律,并以此得到了计算稳态时化学镀铜速率的表达式.同时,有关化学镀铜过程的机理也被推断.

| Abstract: | The kinetic behavior of the cathodic reaction and the anodic reaction during Cu(II)-EDTA-HOHO electroless copper plating has been investigated. The dependence of surface concentration of CuEDTA2-, which is reduced to form copper and covered on specimen, on plating time has been determined. The values of stable plating rate calculated from the equation expressing the relation between the stable plating rate and the equilibrium surface concentration of OuEDTA2-are quite consistent with the corresponding measured values. Finally the actual reaction order of electroless copper plating has also been obtained. |
