Description

[Technical Field]

[0001] The present invention relates to a photosensitive colored composition, a color filter using the same, an image display device, and a solid-state image sensor. [Background technology]

[0002] A color filter is formed by arranging two or more fine strip-shaped filter segments of different hues parallel to each other (in a stripe pattern) or intersecting each other on a transparent substrate such as a glass substrate, or by arranging two or more fine filter segments of different hues sequentially in both the vertical and horizontal directions. The filter segments have small dimensions ranging from a few microns to several hundred microns and are arranged neatly in a predetermined arrangement for each hue.

[0003] Currently, the manufacturing method for color filters involves the steps of: applying a photosensitive colored composition to a transparent substrate such as glass and removing the solvent from the coating by drying; irradiating and curing the coating through a photomask having a desired pattern shape (hereinafter referred to as exposure); then washing and removing the unexposed parts of the coating (hereinafter referred to as development); and then, if necessary, performing a heat treatment (hereinafter referred to as post-bake) to sufficiently harden the cured film to obtain the first color filter segment pattern. By performing the same operation, filter segment patterns of other colors are formed, and the color filter is completed.

[0004] The above development process uses an alkaline developer to wash and remove unexposed areas. However, this process had the problem of causing defects in the pattern shape, such as chipping or peeling of the exposed areas. In addition, when the coating film was exposed to the alkaline developer, a phenomenon called water staining occurred, which affected the coating film. Therefore, there is a need for a photosensitive coloring composition that does not cause defects in the pattern shape or water staining during the development process. Furthermore, there was also the problem that the film thickness of the coating film changed (hereinafter referred to as the residual film rate) due to the elution or vaporization of unreacted substances during the development and post-bake processes.

[0005] Furthermore, in recent years, the miniaturization and increased pixel count of image display devices have led to a trend of smaller area per pixel, prompting consideration of increasing the concentration of colorants in the color filter composition and increasing the film thickness. However, increasing the concentration of colorants or increasing the film thickness has resulted in the problem of wrinkles forming on the film surface during curing.

[0006] As an effort to improve water stains, Patent Document 1 discloses a resist composition containing a fluorine-based surfactant of a specific structure. Furthermore, as an effort to improve pattern defects during development, Patent Document 2 discloses a colored composition containing a polymerizable compound having an alkylene oxide structure. Furthermore, as an effort to improve pattern formation when containing high concentrations of colorants, Patent Document 3 discloses a colored photosensitive resin composition containing a polyfunctional thiol compound and an acetophenone compound. Furthermore, as an effort to improve wrinkles on the surface of the film, Patent Document 4 discloses a colored resin composition containing a photopolymerizable monomer having a double bond equivalent of 400 g / mol or less and having a bisphenol skeleton.

Examples include titanium dioxide, barium sulfate, zinc oxide, lead sulfate, lead yellow, zinc yellow, red iron(III) oxide, cadmium red, ultramarine, Prussian blue, chromium oxide green, cobalt green, amber, and synthetic iron black.

[0035] (dye) The dyes are not particularly limited and include, for example, acid dyes, direct dyes, basic dyes, salt-making dyes, oil-soluble dyes, disperse dyes, reactive dyes, mordant dyes, vat dyes, sulfur dyes, etc. Derivatives of these dyes, or in the form of lake pigments obtained by lake-forming dyes, are also acceptable.

[0036] Furthermore, in the case of acidic dyes having acidic groups such as sulfonic acid or carboxylic acid, or in the form of direct dyes, it is preferable to use inorganic salts of the acidic dye, or salt compounds formed by combining the acidic dye with nitrogen-containing compounds such as quaternary ammonium salt compounds, tertiary amine compounds, secondary amine compounds, or primary amine compounds, or to use them as salt compounds by chlorinating them using resin components having these functional groups, or to use them as sulfonamide compounds by sulfonamide formation, as this results in a colored composition with excellent durability. Furthermore, salt-forming compounds of acid dyes and compounds containing an onium base are also preferred due to their excellent durability, and more preferably, the compound containing the onium base is a resin having a cationic group in its side chain.

[0037] In the case of basic dyes, they can be used after being chlorinated using organic acids, perchloric acid, or their metal salts. Among these, salt compounds of basic dyes are preferred because they have excellent resistance and compatibility with pigments. Furthermore, it is even more preferable to use salt compounds obtained by saturating a basic dye with an organic sulfonic acid, organic sulfuric acid, a fluorine group-containing phosphorus anion compound, a fluorine group-containing boron anion compound, a cyano group-containing nitrogen anion compound, an anion compound having a conjugate base of an organic acid having a halogenated hydrocarbon group, or an acid dye, which act as a counter ion.

[0038] Furthermore, if the pigment skeleton has polymerizable unsaturated groups, it can be used to produce a dye with excellent resistance, which is preferable.

[0039] Examples of dye chemical structures include azo dyes, disazo dyes, azomethine dyes (indoaniline dyes, indophenol dyes, etc.), dipyromethene dyes, quinone dyes (benzoquinone dyes, naphthoquinone dyes, anthraquinone dyes, anthrapyridone dyes, etc.), carbonium dyes (diphenylmethane dyes, triphenylmethane dyes, xanthene dyes, acridine dyes, etc.), quinoneimine dyes (oxazine dyes, thiazine dyes, etc.), azine dyes, polymer dyes, etc. Examples of dye structures derived from dyes selected from tin-based dyes (oxonol-based dyes, merocyanine-based dyes, allylidene-based dyes, styryl-based dyes, cyanine-based dyes, squarylium-based dyes, croconium-based dyes, etc.), quinophthalone-based dyes, phthalocyanine-based dyes, subphthalocyanine-based dyes, perinone-based dyes, indigo-based dyes, thioindigo-based dyes, quinoline-based dyes, nitro-based dyes, nitroso-based dyes, rhodamine-based dyes, and metal complex dyes thereof can be cited, but are not limited to these.

[0040] Among these pigment structures, from the viewpoint of color characteristics such as hue, color separation, and color unevenness, pigment structures derived from pigments selected from azo dyes, xanthene dyes, cyanine dyes, triphenylmethane dyes, anthraquinone dyes, dipyromethene dyes, squarylium dyes, quinophthalone dyes, phthalocyanine dyes, and subphthalocyanine dyes are preferred, and pigment structures derived from pigments selected from xanthene dyes, cyanine dyes, triphenylmethane dyes, anthraquinone dyes, dipyromethene dyes, and phthalocyanine dyes are more preferred. Specific pigment compounds that can form pigment structures are described in "New Edition Dye Handbook" (edited by the Society of Synthetic Organic Chemistry; Maruzen, 1970), "Color Index" (The Society of Dyers and colourists), and "Pigment Handbook" (edited by Okawara et al.; Kodansha, 1986), among others.

[0041] The coloring agent (A) can be used alone or in combination of two or more types.

[0042] The content of the coloring agent (A) is preferably 5 to 70% by mass, and more preferably 10 to 60% by mass, based on 100% by mass of the nonvolatile content of the photosensitive coloring composition.

[0043] (Pigment refinement) It is preferable to use the pigment after it has been finely milled. The milling method is not particularly limited, and for example, wet milling, dry milling, or dissolution milling can all be used. Among these, salt milling by the kneader method, which is a type of wet milling, is preferred. The average primary particle size of the finely milled pigment, as determined by TEM (transmission electron microscopy), is preferably 5 to 90 nm. However, from the viewpoint of dispersibility and contrast ratio, an average primary particle size of 10 to 70 nm is more preferable.

[0044] Salt milling is a process in which a mixture of pigment, water-soluble inorganic salt, and water-soluble organic solvent is mechanically kneaded while heated using a kneader, two-roll mill, three-roll mill, ball mill, attritor, sand mill, etc., and then washed with water to remove the water-soluble inorganic salt and water-soluble organic solvent. The water-soluble inorganic salt acts as a crushing aid, and the pigment is crushed by utilizing the high hardness of the inorganic salt during salt milling. By optimizing the conditions for salt milling the pigment, it is possible to obtain pigments with a very fine primary particle size, a narrow distribution width, and a sharp particle size distribution.

[0045] Examples of water-soluble inorganic salts include sodium chloride, potassium chloride, and sodium sulfate, with sodium chloride (table salt) being preferred from a cost standpoint. The amount of water-soluble inorganic salt used is preferably 50 to 2,000 parts by mass, and more preferably 300 to 1,000 parts by mass, per 100 parts by mass of pigment, considering both processing efficiency and production efficiency.

[0046] The water-soluble organic solvent serves to wet the pigment and the water-soluble inorganic salt, and is not particularly limited as long as it dissolves (miscible) in water and does not substantially dissolve the inorganic salt used. However, since the temperature rises during salt milling and the solvent is prone to evaporation, a high-boiling-point solvent with a boiling point of 120°C or higher is preferred from a safety standpoint. For example, 2-methoxyethanol, 2-butoxyethanol, 2-(isopentyloxy)ethanol, 2-(hexyloxy)ethanol, diethylene glycol, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, triethylene glycol, triethylene glycol monomethyl ether, liquid polyethylene glycol, 1-methoxy-2-propanol, 1-ethoxy-2-propanol, dipropylene glycol, dipropylene glycol monomethyl ether, dipropylene glycol monoethyl ether, liquid polypropylene glycol, etc. are used. The amount of water-soluble organic solvent used is preferably 5 to 1,000 parts by mass, and more preferably 50 to 500 parts by mass, per 100 parts by mass of pigment.

[0047] A resin may be added to the salt milling process as needed. The type of resin is not particularly limited and includes natural resins, modified natural resins, synthetic resins, and synthetic resins modified with natural resins. Among these, it is preferable that the resin is solid at room temperature, insoluble in water, and partially soluble in the organic solvent. The amount of resin added is preferably 2 to 200 parts by mass per 100 parts by mass of pigment.

[0048] [Alkali-soluble resin (B)] The photosensitive composition of the present invention contains an alkali-soluble resin (B). This improves the heat resistance, chemical resistance, and other properties of the cured film.

[0049] The alkali-soluble resin (B) is not particularly limited, and any known resin can be used.

[0050] Alkali-soluble resins (B) can be classified into non-photosensitive alkali-soluble resins and photosensitive alkali-soluble resins. From the viewpoint of developability, alkali-soluble resins (B) preferably have alkali-soluble groups. Examples of alkali-soluble groups include carboxyl groups, phosphate groups, sulfonic acid groups, hydroxyl groups, and phenolic hydroxyl groups, and among these, carboxyl groups are preferred. Furthermore, the alkali-soluble resin (B) may contain thermosetting groups such as epoxy groups or oxetanyl groups.

[0051] (Non-photosensitive alkali-soluble resin) Examples of non-photosensitive alkali-soluble resins include acrylic resins having acidic groups, α-olefin / (anhydride) maleic acid copolymers, styrene / styrene sulfonic acid copolymers, ethylene / (meth)acrylic acid copolymers, or isobutylene / (anhydride) maleic acid copolymers. Among these, acrylic resins having acidic groups and styrene / styrene sulfonic acid copolymers are preferred.

[0052] (Photosensitive alkali-soluble resin) Photosensitive alkali-soluble resins are alkali-soluble resins having polymerizable unsaturated groups. Preferably, the photosensitive alkali-soluble resin is synthesized by, for example, the method shown in (i) or (ii) below. Curing with active energy rays causes three-dimensional crosslinking of the resin, improving the crosslink density and thus improving chemical resistance.

[0053] [Method (i)] Method (i) is, for example, to first synthesize polymers of epoxy group-containing monomers and other monomers. Then, a monocarboxyl group-containing monomer is added to the epoxy group of the polymer, and a polybasic acid anhydride is reacted with the resulting hydroxyl group to obtain a photosensitive alkali-soluble resin.

[0054] Examples of epoxy group-containing monomers include glycidyl (meth)acrylate, methylglycidyl (meth)acrylate, 2-glycidoxyethyl (meth)acrylate, 3,4-epoxybutyl (meth)acrylate, and 3,4-epoxycyclohexyl (meth)acrylate. Among these, glycidyl (meth)acrylate is preferred from the viewpoint of reactivity.

[0059] [Method (ii)] Method (ii) involves synthesizing polymers of, for example, hydroxyl group-containing monomers, monocarboxyl group-containing monomers, and other monomers. Then, the hydroxyl group of the polymer is reacted with the isocyanate group of an isocyanate group-containing monomer.

Here, the acid group can be, for example, a carboxyl group, a sulfonic acid group, a phosphoric acid group, etc. The inclusion of acid-group-containing aromatic urethane (meth)acrylate (C1) is thought to suppress shrinkage during curing by the highly rigid aromatic ring structure of the urethane bond portion, thereby reducing wrinkle formation. Furthermore, the acid group improves the solubility of the alkaline developer, allowing development to be completed in a short time and thus reducing chipping and peeling of the cured film. In addition, the inclusion of lactone-modified (meth)acrylate (C2) is thought to improve the residual film rate by reducing the affinity between water and the film during alkaline development through the highly hydrophobic and thermally stable lactone structure portion, thereby suppressing water staining and reducing decomposition during post-bake. By combining these factors, it is presumed that a photosensitive colored composition was obtained that exhibits less wrinkle formation on the pattern surface, suppresses water staining after development, and has excellent pattern-forming properties (adhesion, shape, and residual film rate).

[0214] Organic solvents (P) can be used alone or in combination of two or more types.

[0215] [Method for producing a photosensitive colored composition] The photosensitive colored composition of the present invention can be produced by dispersing a dispersion by adding, for example, a colorant (A), an alkali-soluble resin (B), a dispersion resin (G), a dye derivative (F), and an organic solvent (P). Subsequently, a polymerizable compound (C), a photopolymerization initiator (D), etc., are added to the dispersion and mixed. The timing of adding each material is arbitrary. Furthermore, the dispersion process can be performed multiple times.

[0216] Distributed processing machines include, for example, two-roll mills, three-roll mills, ball mills, horizontal sand mills, vertical sand mills, annular bead mills, or attritors.

[0217] The average dispersed particle size (secondary particle size) of the pigment in the dispersion is preferably 30 to 200 nm, and more preferably 40 to 200 nm. Having an appropriate particle size makes it easier to obtain a photosensitive colored composition with high dispersion stability.

[0218] The method for measuring the average dispersed particle diameter (secondary particle diameter) is, for example, to use Nikkiso's Microtrac UPA-EX150, which employs dynamic light scattering (FFT power-spectrum method), with particle permeability set to absorption mode, particle shape to non-spherical, and D50 particle diameter as the average diameter. The diluent solvent for measurement is the same organic solvent used for dispersion, and it is preferable to measure immediately after sample preparation of ultrasonically treated samples to obtain results with less variation.

[0219] The photosensitive colored composition is preferably subjected to centrifugation, sintering filter filtration or membrane filter filtration to remove coarse particles of 5 μm or larger, preferably coarse particles of 1 μm or larger, more preferably coarse particles of 0.5 μm or larger, and any mixed dust. The photosensitive colored composition of the present invention preferably contains substantially no particles of 0.5 μm or larger, and more preferably contains no particles of 0.3 μm or smaller.

[0220] <Color Filter> The color filter of the present invention comprises a substrate and filter segments formed from the photosensitive coloring composition of the present invention. The color filter segments preferably have red, green, and blue filter segments by appropriately selecting the type of colorant (A) used. In addition, the color filter may have magenta, cyan, and yellow filter segments instead of or in addition to the above color filter segments. Examples of substrates include transparent substrates and reflective substrates. Transparent substrates include, for example, glass substrates. Reflective substrates include, for example, substrates that use aluminum electrodes or thin metal films as reflective surfaces.

[0221] [How to manufacture color filters] The method for manufacturing a color filter is not particularly limited, and for example, it can be manufactured by performing the steps of: (1) applying a photosensitive colored composition onto a substrate to form a layer of the composition; (2) exposing the layer in a patterned manner through a mask; (3) alkaline developing the unexposed areas to form a patterned cured film; and (4) heat-treating the pattern (post-bake).

[0222] The manufacturing method of color filters will be described in detail below. (Process (1)) Step (1) of forming a layer of composition involves applying the photosensitive colored composition onto a substrate by methods such as rotary coating, roll coating, slit coating, casting coating, or inkjet coating, and drying (pre-baking) it at a temperature of 50 to 120°C for 10 to 120 seconds using an oven, hot plate, etc., if necessary. Examples of the substrate include glass substrates and silicon substrates. For example, an image sensor such as a CCD or CMOS may be formed on the surface of the silicon substrate. In addition, a primer layer may be provided on the substrate as needed to improve adhesion with the upper layer, prevent diffusion of materials, and flatten the substrate surface. The layer thickness is preferably 0.05 to 10.0 μm after drying, and more preferably 0.3 to 5 μm.

[0223] (Process (2)) In the exposure process, the layer obtained in step (1) is exposed to a specific pattern through a mask using an exposure device such as a stepper. This results in a cured film. Examples of radiation used for exposure include ultraviolet rays such as g-rays, h-rays, and i-rays.

[0224] (Step (3)) The cured film obtained in step (2) is subjected to alkaline development, which causes the unexposed portion of the composition to dissolve in the alkaline aqueous solution, leaving only the cured portion and resulting in a patterned cured film. Examples of developing solutions include alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium metasilicate, aqueous ammonia, ethylamine, diethylamine, dimethylethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, choline, pyrrol, piperidine, and 1,8-diazabicyclo-[5.4.0]-7-undecene. The developer concentration is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. The pH of the alkaline developer is preferably 11-13, and more preferably 11.5-12.5. Using a moderate pH suppresses pattern roughness and peeling, and improves the residual film rate after development.

[0225] Development methods include, for example, the dip method, spray method, and pador method. The development temperature is preferably 15 to 40°C. After alkaline development, it is preferable to wash with pure water.

[0226] (Step (4)) The heat treatment (post-bake) is used to fully harden the patterned cured film obtained in step (3) by heating. The heating temperature for post-bake is preferably 100 to 300°C, and more preferably 150 to 250°C. The heating time is preferably 2 minutes to 1 hour, and more preferably 3 minutes to 30 minutes.

[0227] <Image display device> The image display device of the present invention is equipped with the color filter of the present invention. The form used in the image display device is not particularly limited, as long as it functions as an image display device. For example, the configuration described in "Next-Generation Liquid Crystal Display Technology" (by Tatsuo Uchida, published by Kogyo Chosakai Co., Ltd. in 1994) is one such example. For definitions of image display devices and details of various image display devices, see, for example, "Electronic Display Devices" (by Akio Sasaki, Kogyo Chosakai Co., Ltd., published in 1990) and "Display Devices" (by Junsho Ibuki, Sangyo Tosho Co., Ltd., published in 1989).

[0228] <Solid-state image sensor> The solid-state image sensor of the present invention is equipped with the color filter of the present invention. The form used for the solid-state image sensor is not particularly limited, but for example, it may have a substrate on which a plurality of photodiodes constituting the light-receiving area of ​​the solid-state image sensor (CCD image sensor, CMOS image sensor, etc.) and transfer electrodes made of polysilicon or the like are provided, a light-shielding film with an opening only for the light-receiving portion of the photodiode is provided on the photodiode and transfer electrodes, a device protective film made of silicon nitride or the like is provided on the light-shielding film so as to cover the entire surface of the light-shielding film and the light-receiving portion of the photodiode, and a color filter on the device protective film. Furthermore, it may have a configuration in which a light-gathering means (e.g., a microlens, etc.; the same applies hereinafter) is provided on the device protective film and below the color filter (on the side closer to the substrate), or a configuration in which the light-gathering means is provided on the color filter. In addition, the color filter may have a structure in which a hardened film forming each colored pixel is embedded in a space partitioned, for example, in a grid pattern by partitions. In this case, it is preferable that the partitions have a low refractive index with respect to each colored pixel. The imaging device equipped with the solid-state image sensor of the present invention can be used not only in digital cameras and electronic devices with imaging functions (mobile phones, smartphones, etc.), but also in in-vehicle cameras and surveillance cameras. [Examples]

[0229] The present invention will be described in more detail below with reference to examples. However, the present invention is not limited to these examples. Note that "parts" refers to "parts by mass" and "%" refers to "percentage by mass". Furthermore, in this invention, non-volatile content or non-volatile content concentration refers to the mass residue after standing in an oven at 280°C for 30 minutes.

[0230] Before presenting the examples, each measurement method will be explained.

[0231] The weight-average molecular weight (Mw), number-average molecular weight (Mn), and acid value (mgKOH / g) of the resin are as follows:

[0232] (Average molecular weight of alkali-soluble resin and dispersion resin) Alkali solubility and the number-average molecular weight (Mn) and weight-average molecular weight (Mw) of the dispersed resin were measured by gel permeation chromatography (GPC) equipped with an RI detector. An HLC-8220GPC (Tosoh Corporation) was used, with two separation columns connected in series. Both columns were packed with two TSK-GEL SUPER HZM-N columns. Measurements were performed at an oven temperature of 40°C, using tetrahydrofuran (THF) solution as the eluent, and a flow rate of 0.35 ml / min. The sample was dissolved in a solvent consisting of 1% by mass of the above eluent, and 20 microliters were injected. Average molecular weights are expressed on a polystyrene basis.

[0233] (Acid value of alkali-soluble resins and dispersion resins) 0.5 to 1 g of alkali-soluble resin and dispersion resin solution were mixed with 80 ml of acetone and 10 ml of water and stirred to dissolve uniformly. A 0.1 mol / L aqueous KOH solution was used as the titrant, and the solution was titrated using an automatic titrator ("COM-555," manufactured by Hiranuma Sangyo Co., Ltd.) to measure the acid value (mgKOH / g). The acid value per unit of non-volatile content of the resin was then calculated from the acid value of the resin solution and the non-volatile content concentration of the resin solution.

[0234] (Amine value of dispersed resin) The amine value of the dispersion resin is calculated by converting the total amine value (mgKOH / g), which was measured according to the ASTM D 2074 method, into a non-volatile content value.

Then, illuminating it with a high-pressure mercury lamp at an intensity of 30 mW / cm² through a mask having a 100 μm wide stripe pattern was performed. 2 40 mJ / cm² 2 The samples were exposed to ultraviolet light under the specified conditions. Subsequently, they were developed by immersion in an aqueous developer containing 0.12% nonionic surfactant and 0.04% potassium hydroxide at 23°C for 40 seconds, and then washed with pure water. The resulting patterns were observed using a Nikon ECLIPSE LV100POL Model optical microscope, and the degree of discoloration was evaluated. A score of 3 or higher was considered practical. 5: There were no water stains. 4. Water stains accounted for less than 10% of the total area. 3. Water stains accounted for 10% to less than 20% of the total area. 2: Water stains accounted for 20% to less than 30% of the total area. 1: Water stains covered more than 30% of the surface.

[0280] <Fabrication of substrates for pattern formation evaluation> The obtained photosensitive colored composition was coated onto a 100 mm x 100 mm, 0.7 mm thick glass substrate (Corning Eagle 2000) by spin coating to a dry film thickness of 3.0 μm, and dried on a hot plate at 70°C for 1 minute. After cooling the substrate to room temperature, illuminating it at 30 mW / cm² was performed using a high-pressure mercury lamp through photomasks with 100 μm wide (200 μm pitch) and 10 μm wide (20 μm pitch) stripe patterns. 2 40 mJ / cm² 2 The substrate was exposed to light. Subsequently, this substrate was spray-developed using an aqueous developer containing 0.12% by mass of a nonionic surfactant and 0.04% by mass of potassium hydroxide at 23°C. After that, it was washed with deionized water, air-dried, and heated in a clean oven at 230°C for 30 minutes to obtain a substrate for pattern formation evaluation. Spray development was performed for the shortest possible time that allowed for pattern formation without any development residue for each photosensitive coloring composition.

[0281] [Pattern formation evaluation (1): Adhesion] Fine line patterns with a width of 6 to 25 μm on substrates prepared using the above method were observed with an optical microscope to confirm the minimum line width of the remaining fine line patterns.

A score of 3 or higher is considered practical. 5: Taper angle of 30 degrees or more and less than 50 degrees 4: Taper angle 50 degrees or more and less than 60 degrees 3: Taper angle less than 30 degrees or 60 degrees or more but less than 70 degrees 2: Taper angle 70 degrees or more and less than 90 degrees 1: Taper angle of 90 degrees or more

[0283] [Pattern formation evaluation (3): Residual film rate] During the preparation of the substrate for evaluating pattern formation, spray development was performed, followed by washing with deionized water and air drying. The film thickness of the coating was then measured. This film thickness was defined as the post-development film thickness. Subsequently, the substrate was heated in a clean oven at 230°C for 30 minutes, and the film thickness was measured again at the same location where the post-development film thickness was measured. This film thickness was defined as the post-bake film thickness. The residual film percentage was calculated from the two film thicknesses using the following formula. A percentage of 3 or higher is considered practical. The film thickness was measured using a Dektak 3030 (manufactured by Nippon Vacuum Technology Co., Ltd.). Formula: Residual film percentage (%) = Film thickness after baking ÷ Film thickness after development × 100 5: Remaining film rate 85% or more 4: Residual film rate 80% or more but less than 85% 3: Residual film rate 75% or more but less than 80% 2: Residual film rate 70% or more but less than 75% 1: Residual film rate less than 70%

[0284] [Surface wrinkle evaluation] The pattern surface of the above pattern-forming evaluation substrate was observed using an optical microscope (Olympus Optical Co., Ltd. "BX-51", magnification: 200x). A score of 3 or higher is considered practical. 5: No wrinkles are observed on the surface of the pattern. 4: Very slight wrinkles are observed on the surface of the pattern. 3: Slight wrinkles are observed on the surface of the pattern. 2: Wrinkles are observed on the surface of the pattern. 1: Severe wrinkles are observed on the surface of the pattern.
