Thiazole and thiocarbamide based chemicals for use with oxidative etchant solutions |
摘要 |
Metal surfaces, particularly copper surfaces, which are oxidatively micro-etched to increase surface area, are provided acid-resistance by exposure to a thiazole compound and/or a thiocarbamide compound. The thiazole compound and/or thiocarbamide compound may be provided either in the oxidative micro-etching solution or provided in a post-micro-etching solution.
