Abstract:
1. A cleaning material for removing particulate contaminants from a semiconductor substrate surface, comprising: a liquid; carboxylic acid solid components dispersed in a substantially uniform manner in the liquid, wherein a concentration of the carboxylic acid solid components in the liquid exceeds a solubility limit of the carboxylic acid solid components in the liquid, and wherein the carboxylic acid solid components are defined by a carbon number of at least four, wherein the carboxylic acid solid components are defined to interact with the particulate contaminants on the semiconductor substrate surface to remove the particulate contaminants from the semiconductor substrate surface; and a hydrolyzing agent in a form of ammonium hydroxide (NH
