摘要:
The invention provides an agent for post-etch treating a silicon dielectric film, including: at least one nitrogen-containing substance selected from the group consisting of ammonium bases and amine compounds; an acid; and at least one silicon-containing compound containing silicon, carbon and hydrogen. According to the present invention, it becomes possible to suppress an increase in the dielectric constant of a silicon dielectric film caused by etching.
