摘要: A cleaning solution for cleaning microelectronic substrates, particularly for post-CMP or via formation cleaning. The cleaning solution comprises a quaternary ammonium hydroxide, an organic amine, a corrosion inhibitor, optionally an organic acid, and water. A preferred cleaning solution comprises tetramethylammonium hydroxide, monoethylanolamine, gallic acid ascorbic acid, and water with the alkalinity of the cleaning solution greater than 0.073 milliequivalents base per gram of solution.
