Patent ID: 7951717

Claim:
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; 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; the treating liquid having a pH ranging from 4 to 9.
