Abstract
Metal surfaces, particularly copper surfaces, which are oxidatively micro-etched to increase surface area through the use of molybdenum. The micro-etch solutions contain a proton source, e.g., a mineral acid, an oxidizer agent, e.g., hydrogen peroxide, an azole compound, and a molybdenum source. These micro-etched surfaces can further be rendered acid-resistant 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.
