20080206668 | NEGATIVE RESIST COMPOSITION AND PATTERN FORMING METHOD USING THE SAME - A negative resist composition includes: (A) a compound having at least one episulfide structure (a three-membered ring structure comprising two C atoms and one S atom); (B) an alkali-soluble resin; and (C) a compound capable of generating an acid upon irradiation with actinic rays or radiation, and a pattern forming method using the composition. | 08-28-2008 |
20080241742 | SURFACE-TREATING AGENT FOR PATTERN FORMATION AND PATTERN-FORMING METHOD USING THE SURFACE-TREATING AGENT - A surface-treating agent for forming a resist pattern, includes: a compound represented by formula (1) as defined in the specification, wherein the surface-treating agent is used in a step between a formation of a first resist pattern on a first resist film and a formation of a second resist film on the first resist pattern to form a second resist pattern, and a pattern-forming method uses the surface-treating agent. | 10-02-2008 |
20100040971 | PATTERN FORMING METHOD, AND RESIST COMPOSITION, DEVELOPER AND RINSING SOLUTION USED IN THE PATTERN FORMING METHOD - A pattern forming method comprising a step of applying a resist composition whose solubility in a negative tone developer decreases upon irradiation with an actinic ray or radiation and which contains a resin having an alicyclic hydrocarbon structure and a dispersity of 1.7 or less and being capable of increasing the polarity by the action of an acid, an exposure step, and a development step using a negative tone developer; a resist composition for use in the method; and a developer and a rinsing solution for use in the method, are provided, whereby a pattern with reduced line edge roughness and high dimensional uniformity can be formed. | 02-18-2010 |
20100040972 | PATTERN FORMING METHOD, AND RESIST COMPOSITION, DEVELOPER AND RINSING SOLUTION USED IN THE PATTERN FORMING METHOD - A pattern forming method comprising a step of applying a resist composition whose solubility in a negative tone developer decreases upon irradiation with an actinic ray or radiation and which contains a resin having an alicyclic hydrocarbon structure and a dispersity of 1.7 or less and being capable of increasing the polarity by the action of an acid, an exposure step, and a development step using a negative tone developer; a resist composition for use in the method; and a developer and a rinsing solution for use in the method, are provided, whereby a pattern with reduced line edge roughness and high dimensional uniformity can be formed. | 02-18-2010 |
