发明名称 POST-CMP TREATING LIQUID AND MANUFACTURING METHOD OF SEMICONDUCTOR DEVICE USING THE SAME
摘要 Post-CMP treating liquids are provided, one of which includes water, an amphoteric surfactant, an anionic surfactant, a complexing agent, resin particles having carboxylic group and sulfonyl group on their surfaces, a primary particle diameter thereof ranging from 10 to 60 nm, and tetramethyl ammonium hydroxide. Another includes water, polyphenol, an anionic surfactant, ethylene diamine tetraacetic acid, resin particles having carboxylic group and sulfonyl group on their surfaces, a primary particle diameter thereof ranging from 10 to 60 nm, and tetramethyl ammonium hydroxide. Both of the treating liquids have a pH ranging from 4 to 9, and exhibit a polishing rate both of an insulating film and a conductive film at a rate of 10 nm/min or less.
