Abstract:
A resist underlayer film composition is excellent in resistance to a basic hydrogen peroxide aqueous solution in gap-filling and planarization characteristics having a dry etching characteristic; a patterning process and method for forming a resist underlayer film, wherein the resist underlayer film composition is used for a multilayer resist method, the composition comprising: (a1) one, or two or more, of a compound represented by following general formula (x); and (b) an organic solvent, wherein n 01  represents an integer of 1 to 10; when n 01  is 2, w represents a sulfinyl group, a sulfonyl group, an ether group, or a divalent organic group having 2 to 50 carbon atoms; when n 01  is an integer other than 2, w represents an n 01 -valent organic group having 2 to 50 carbon atoms; and y represents a single bond or divalent connecting group having 1 to 10 carbon atoms and optionally having an oxygen atom.

Claim (Index 11):
A patterning process, wherein the patterning process is to form a pattern on a substrate to be processed and comprises:\n (I-1) forming a resist underlayer film on the substrate to be processed by using the resist underlayer film composition according to  claim 1 , (I-2) forming a resist upper layer film on the resist underlayer film by using a photoresist composition, (I-3) forming a pattern on the resist upper layer film by developing the resist upper layer film by using a developer after the resist upper layer film is pattern-exposed, and (I-4) transcribing the pattern to the resist underlayer film by dry etching using as a mask the resist upper layer film formed with the pattern.
