摘要:
An object of the present invention is to provide, inexpensively and safely, a luminescence system, a method of luminescence, and a luminescent substance based on a novel luminescence mechanism that luminesces at high efficiency. The present invention relates to a luminescence system, wherein a first chemical substance changes into a second chemical substance having a chemical structure that is different from that of the first chemical substance and thereby luminesces. The present invention preferably relates to the luminescence system, wherein the second chemical substance turns back into the first chemical substance after luminescence.

Methods are disclosed for forming topographical features. In one method, a pre-patterned structure is provided which comprises i) a support member having a surface and ii) an element for topographically guiding segregation of a polymer mixture including a first polymer and a second polymer, the element comprising a feature having a sidewall adjoined to the surface. The polymer mixture is disposed on the pre-patterned structure, wherein the disposed polymer mixture has contact with the sidewall and the surface. The first polymer and the second polymer are segregated in a plane parallel to the surface, thereby forming a segregated structure comprising a first polymer domain and a second polymer domain. The first polymer domain and/or the second polymer domain are lithographically patterned, thereby forming topographical features comprising at least one of i) a first feature comprising a lithographically patterned first polymer domain and ii) a second feature comprising a lithographically patterned second polymer domain.

A method for processing a structure. The structure is formed and includes a substrate, a substructure having a sidewall and disposed on the substrate, a first polymer structure disposed on the substrate, and a second polymer structure disposed on the substrate such that the first polymer structure is disposed between the sidewall and the second polymer structure. An aspect ratio of the first polymer structure, the second polymer structure, or both is reduced in a reducing step. One polymer structure (i.e., the first polymer structure or the second polymer structure) is selectively removed from the structure such that a remaining polymer structure (i.e., the second polymer structure or the first polymer structure) remains disposed on the external surface of the substrate after the one polymer structure has been selectively removed, wherein the aspect ratio of the remaining polymer structure was reduced in the reducing step.

A pattern-forming method includes applying a photoresist composition to a substrate to form a resist film. The photoresist composition includes an acid generator and a first polymer that includes an acid-dissociable group. The resist film is exposed. The resist film is developed using a developer having an organic solvent content of 80 mass % or more to form a prepattern of the resist film. A polymer film having a phase separation structure in a space defined by the prepattern is formed using a composition that includes a plurality of second polymers. A part of the phase separation structure of the polymer film is removed.

A negative-tone radiation-sensitive composition includes a polymer, a photoacid generator, and a solvent. The polymer has a polystyrene-reduced weight average molecular weight of 4000 to 200,000, and is obtained by hydrolysis and condensation of at least one hydrolyzable silane compound among compounds shown by RaSi(OR1)4-a, Si(OR2)4 and R3x(R4O)3-xSi—(R7)z—Si(OR5)3-yR6y. “R” represents a fluorine atom, an alkylcarbonyloxy group, or a linear or branched alkyl group having 1 to 5 carbon atoms. “R1” represents a monovalent organic group. “R2” represents a monovalent organic group. “R3” and “R6” individually represent a fluorine atom, an alkylcarbonyloxy group, or a linear or branched alkyl group having 1 to 5 carbon atoms “R4” and “R5” individually represent a monovalent organic group. “R7” represents an oxygen atom, a phenylene group, or a group —(CH2)m—. The content of units derived from the compound RaSi(OR1)4-a is 50 to 100 mol % of the total units forming the polymer.

A pattern-forming method includes forming a prepattern on a substrate. A space other than a space in which the prepattern is formed on the substrate is filled with a resin composition containing a compound which is diffusible into the prepattern. The compound is diffused into a part of the prepattern. Portions in which the compound is undiffused in the prepattern are removed using a removing liquid.
