Abstract:
The present invention provides a resist multilayer film-attached substrate, including a substrate and a resist multilayer film formed on the substrate, in which the resist multilayer film has an organic resist underlayer film difficultly soluble in ammonia hydrogen peroxide water, an organic film soluble in ammonia hydrogen peroxide water, a silicon-containing resist middle layer film, and a resist upper layer film laminated on the substrate in the stated order. There can be provided a resist multilayer film-attached substrate that enables a silicon residue modified by dry etching to be easily removed in a wet manner with a removing liquid harmless to a semiconductor apparatus substrate and an organic resist underlayer film required in the patterning process, for example, an ammonia aqueous solution containing hydrogen peroxide called SC1, which is commonly used in the semiconductor manufacturing process.

Claim (Index 18):
A patterning process comprising:\n photo-exposing the resist upper layer film of the resist multilayer film-attached substrate according to  claim 2 , and developing the resist upper layer film with a developer to form a pattern in the resist upper layer film; transferring the pattern to the silicon-containing resist middle layer film by etching using the resist upper layer film having the formed pattern as an etching mask; transferring the pattern to the organic film and the organic resist underlayer film by etching using the silicon-containing resist middle layer film having the transferred pattern as an etching mask; removing the silicon-containing resist middle layer film having the transferred pattern and the organic film having the transferred pattern by treatment with ammonia hydrogen peroxide water; and transferring the pattern to the substrate by using the organic resist underlayer film having the transferred pattern as a mask.
