CTS-9315591 Columbia University Alan C. West ABSTRACT Spatial and temporal variation of electrodeposition for two specific cathode geometries in the presence of laminar, tangential, periodic flow will be investigated. Current distributions are to be determined for a cathode at the base of a recessed insulating cavity and for a set of three closely spaced cathodes. Experimental measurements of the codeposition of copper with trace amounts of silver will be compared to results from numerical simulations with the transport equations. Improved electrodeposition has the potential for higher quality products in a broad range of industries from plating to microelectronics.

CTS-9315591哥伦比亚大学艾伦·C·韦斯特摘要研究了在层流、切向、周期流存在下，两种特定阴极几何形状的电沉积的空间和时间变化。电流分布将被确定为在凹陷的绝缘腔的底部的阴极和一组三个紧密间隔的阴极。铜与微量银共沉积的实验测量结果将与输运方程的数值模拟结果进行比较。改进的电沉积在从电镀到微电子的广泛行业中具有更高质量的产品的潜力。
