Patent ID: 7504341

Claim:
A method of manufacturing a semiconductor device, comprising tbe steps of: forming one or more insulation films over a substrate, said one or more insulation films including an insulation film at a top thereof; coating the insulation film with a substrate processing agent; providing resist onto the insulation film coated with the substrate processing agent; lithographically forming a pattern of the resist; and dry-etching the insulation film by using the resist as a mask, wherein the substrate processing agent contains at least a solvent and an acid generating agent, wherein the solvent ranges between 90% to 99.99% of the substrate processing agent, wherein the acid generating agent ranges between 0.0 1% to 10% of the substrate processing agent wherein the acid generating agent generates an acid with an acid strength weaker than an acid strength of an acid supplied to an interface between the resist and the insulation film from the resist or from the insulation film.
