Micro-etch solution for producing metal surface topography

摘要: Metal surfaces, particularly copper which are oxidatively micro-etched to increase surface area through the use of molybdenum. The micro-etch solutions contain a proton source, e.g., mineral acid, an oxidizer agent, hydrogen peroxide, azole compound, and molybdenum source. These surfaces can further be rendered acid-resistant by exposure thiazole compound and/or thiocarbamide compound. may provided either in oxidative micro-etching solution or post-micro-etching solution.
