Selective gold plating |
摘要 |
A process is described for selectively electroplating gold on metallic surfaces containing copper using a chromate film as a plating mask. This procedure permits reduced use of gold without adversely affecting device performance. In addition, chromate films may be patterned with relatively high dimensional resolution and control so as to achieve gold plating patterns useful in electronic and integrated circuits.
