Definitions
- the present invention relates to a lithography rinsing liquid that is effective for preventing pattern collapse during formation of a fine pattern having a high aspect ratio.
- pattern collapse is a phenomenon in which, when a large number of patterns are formed in parallel on a substrate, adjacent patterns come close to each other so as to lean against each other, and in some cases, the base force is broken or peeled off. If such a pattern collapse occurs, a desired product cannot be obtained, which causes a decrease in product yield and reliability.
- a method of using a rinse solution whose surface tension is adjusted to 30 to 50 dyneZcm by adding alcohols, ketones or carboxylic acids (JP7-140674A), at least one of the developer solution and the rinse solution
- Method of adding a fluorinated surfactant to the surface (CiP7-142349A), the water rinsing process and the specific gravity higher than water when the resist is immersed in water, and the surface tension is lower
- a method comprising a step of drying after substitution with a water-miscible liquid such as perfluoroalkyl polyether (JP7-226358A), wherein an amino group, an imino group or an amo-dum group and a carbon number of 1 to
- a rinsing agent composition (JP11-295902A) having 20 hydrocarbon groups and a nitrogen-containing compound having a molecular weight of 45 to 10,000, and a fluorinated carboxylic acid, a fluorinated sulfonic acid
- PFOS perfluorooctanesulfonic acid
- SNUR Important New Use Regulation
- a fluorine-based surfactant containing an easy-to-handle fluorinated surfactant that is environmentally friendly and having the same effect as when perfluorooctanesulfonic acid is used is used. Surfactants are needed.
- the present invention provides a high-quality product that has a contact angle of 40 degrees or less, easily wets the surface, and can effectively prevent pattern collapse by modifying the surface of the resist pattern to a contact angle of 70 degrees or more.
- the purpose of the present invention is to provide a novel rinsing liquid capable of producing the same.
- the present inventors have developed a rinsing liquid that can effectively prevent pattern collapse during the formation of a photoresist pattern by lithography technology and that does not impair the physical properties of the resist pattern after processing.
- a solution containing a fluorine compound having a specific functional group before or after the rinsing treatment with water could result in contact with the resist pattern surface without deteriorating the physical properties of the resist itself.
- the inventors have found that the contact angle with respect to the liquid can be increased to 70 degrees or more to prevent pattern collapse, and the present invention has been accomplished based on this finding.
- the present invention provides a compound represented by the general formula
- R 1 and R 2 are an alkyl group having 1 to 5 carbon atoms or a substituted alkyl group in which part or all of the hydrogen atoms are substituted by fluorine atoms, and R 1 and R 2 are linked to each other To form a 5- or 6-membered ring with SO and N!
- R is a carbon atom in which some or all of the hydrogen atoms have been replaced by fluorine atoms.
- R is an at least partially fluorinated alkyl group having 8 to 20 carbon atoms
- lithography rinse solution which has at least one solution selected from water or alcohol-based solvent-soluble fluorine compounds represented by the formula:
- R 1 and R 2 represent an alkyl group or a substituted alkyl group in which all hydrogen atoms have been replaced by fluorine atoms, for example, a perfluoromethyl group, a perfluoroethyl group, Perfluoroalkyl groups such as fluoropropyl and perfluorobutyl are preferred. Particularly preferably, R 1 and R 2 are linked to form a 5- or 6-membered ring together with the SO group and the nitrogen atom to which they are bonded, and the hydrogen atom of R 1 and R 2 is
- R in the general formula ( ⁇ ) is f at least partially fluorinated having 1 to 5 carbon atoms.
- substituent of the substituted alkyl group include a hydroxyl group, an alkoxy group, a carboxyl group and an amino group. This R is especially f
- the whole thing is fluorinated and the thing is preferred.
- Examples of such a compound include perfluoro (3-morpholinopropionic acid), perfluoro (2-methyl-3-morpholinopropionic acid), and perfluoro (4-morpholinobutyric acid). Particularly preferred among these are the formulas
- These fluorine compounds can be produced by fluorinating an unfluorinated compound as a raw material by a known method, for example, an electrolytic fluorination method. Further, a lithium salt in which R 1 and R 2 in the general formula (I) are a trifluoromethyl group or a pentafluoroethyl group is commercially available under the registered trademark “Florald”.
- fluorine compound represented by the general formula ( ⁇ ) part or all of the hydrogen atoms of decane carboxylic acid, dodecane carboxylic acid, tetradecane carboxylic acid, and hexadecane carboxylic acid are substituted with fluorine atoms. Particularly preferred are those in which all of the hydrogen atoms are replaced by fluorine atoms, for example, perfluoro (decanecarbonic acid).
- These fluorine compounds are usually used as a solution dissolved in water or an alcohol-based solvent such as methyl alcohol or a mixture of ethyl alcohol and water.
- the fluorine compound of higher fatty acid does not dissolve in water, it is necessary to use, for example, a mixed solvent of water and an alcohol-based solvent such as methyl alcohol, isopropyl alcohol or trifluoroethanol.
- a mixed solvent of water and an alcohol-based solvent such as methyl alcohol, isopropyl alcohol or trifluoroethanol.
- the mixing ratio of water and the alcohol solvent is 60:40 by volume !, and is in the range of 99: 1.
- the rinsing liquid of the present invention contains the fluorine compound of the general formulas (I) to ( ⁇ ) in an amount of 0.001 to 5.0% by mass, preferably 0.01 to 1% by weight of water or L at a concentration of 0% by mass. It is prepared by dissolving in a mixed solvent of water and an alcohol solvent.
- the treatment of the resist pattern with the rinsing liquid is performed by applying a force of dipping the developed resist pattern into the rinsing liquid before drying, or applying or spraying the rinsing liquid on the surface of the resist pattern. Even if the contact angle of the resist pattern surface with the liquid is as small as 40 degrees or less by this treatment, it can be increased to 70 degrees or more, and in some cases, 90 degrees or more. By performing the drying process in, the pattern can be dried without falling down.
- the processing can be performed by increasing the temperature of the rinsing liquid.
- the surface tension of the water drops to 62.6 dyneZcm at 80 ° C, which is 72 dyneZcm at 24 ° C. Turn fall can be reduced.
- An anti-reflective coating agent [Brewer's product name, "ARC29 A”] was applied on a silicon wafer, and heated at 215 ° C for 60 seconds to form an anti-reflective film with a thickness of 77 nm. .
- this antireflection film as a resin component, the formula

- PFMO 3 bis (heptafluoropropylsulfol-) amine
- PDC commercially available perfluoro (decanecarboxylic acid) having a 0.005% aqueous solution power
- This rinsing treatment was performed by dropping the above rinsing liquid at 500 rotations for 3 seconds and then rinsing with pure water for 20 seconds.
- the contact angle on the resist pattern surface before and after each rinsing treatment was measured using a contact angle meter (manufactured by Kyowa Interface Science Co., Ltd., product name “CA-XI50”). Table 1 shows the results.
- the rinsing solution of the present invention can be used to form a fine line of 30 to 100 nm and a resist pattern of an 'and' space, particularly a resist pattern having a high aspect ratio of 3 or more, which is very easy to collapse. Even if there is no pattern collapse, it is possible to form a pattern that does not impair the resist pattern characteristics. Therefore, the present invention is suitable for manufacturing semiconductor devices such as LSIs and ULSIs using a lithography method, particularly devices having a high aspect ratio.
