Abstract:
1. A method for manufacturing a semiconductor device comprising: depositing a conductive material above an insulating film formed above a semiconductor substrate and having a recess, thereby forming a conductive film; polishing the conductive film to expose a surface of the insulating film while burying the conductive material in the recess, thereby forming a buried wiring layer; and treating a surface of the buried wiring layer and the surface of the insulating film using a treating liquid without substantially polishing these surfaces, the treating liquid comprising water; resin particles having, on their surfaces, carboxylic group and sulfonyl group, and a primary particle diameter ranging from 10 to 60 nm, the resin particles being incorporated at a concentration ranging from 0.01 to 1 wt %; a first surfactant having a carboxylic group; a second surfactant having a sulfonyl group; and tetramethyl ammonium hydroxide; the treating liquid having a pH ranging from 4 to 9.
