[0002] In recent years, with the popularization of digital cameras and mobile phones with cameras, the demand for solid-state imaging devices such as charge-coupled devices (CCD) image sensors has increased significantly. Color filters are used as core devices for displays or optical components. Color filters usually have pixels of the three primary colors of red, green, and blue, and play a role in decomposing transmitted light into the three primary colors.

[0003] The colored pixels of each color of the color filter are manufactured using a coloring composition containing a colorant. Patent Document 1 describes forming pixels of a color filter using a coloring composition containing a pigment containing an azomethine metal complex pigment, a pigment derivative having two sulfonic acid groups introduced into the azomethine metal complex pigment, a resin, and a solvent.

[0087] <Coloring Composition>

[0088] The coloring composition of the present invention is characterized in that it contains:

[0089] At least one compound S selected from the group consisting of a compound S-1 represented by formula (1) and a compound S-2 in which the compound S-1 is coordinated to a metal atom;

[0090] pigment;

[0091] Resin P; and

[0092] Solvents,

[0093] The resin P contains at least one selected from the group consisting of a grafted resin P-1, a block copolymer P-2, and a resin P-3, wherein the grafted resin P-1 has a grafted chain containing at least one structure selected from the group consisting of a polyester structure, a polyether structure, and a poly(meth)acrylic acid structure.

[0094] The block copolymer P-2 contains at least one structure selected from the group consisting of a polyester structure, a polyether structure and a poly(meth)acrylic acid structure.

[0095] The resin P-3 is a polymer chain having at least one structure selected from a polyester structure, a polyether structure and a poly(meth)acrylic acid structure, at least one end of which is capped with an acid group. Hereinafter, the grafted resin P-1, the block copolymer P-2 and the resin P-3 are also collectively referred to as specific resins.

[0096] The coloring composition according to the present invention can form pixels that suppress the generation of pixel defects caused by the developer and have excellent developer resistance. For example, when forming pixels by patterning using a coloring composition by photolithography, it is possible to suppress the generation of pixel defects caused by the developer during development. In addition, in the case of manufacturing a filter having pixels of multiple colors by sequentially forming pixels of each color using coloring compositions of multiple colors, when forming pixels after the second color, the pixels formed in the previous process are also exposed to the developer, but by using the coloring composition of the present invention, pixels with excellent developer resistance can be formed, so when forming pixels after the second color, it is possible to suppress damage caused by the developer of the pixels formed before, and it is possible to suppress the generation of defects.

[0097] The colored composition of the present invention can form pixels having excellent developer resistance even when forming pixels having a fine line width of 1.0 μm or less (preferably 0.9 μm or less), and is therefore effective in forming pixels having a fine line width of 1.0 μm or less (preferably 0.9 μm or less).

[0098] Furthermore, the coloring composition of the present invention has a wide exposure latitude. Therefore, when patterning is performed by photolithography using the coloring composition of the present invention, the permissible range of exposure when forming pixels of a desired line width is wide, and thus photolithography is excellent.

[0099] The detailed reason for this effect is not clear, but it can be speculated as follows. It is speculated that compound S-1 has an aromatic ring and an azomethine structure, and compound S can form a strong intermolecular bond with the pigment. In addition, it can be speculated that R in formula (1) representing compound S-1 2 ~R 9 One of them has a group represented by formula (R-1), and compound S can form a strong intermolecular bond with a specific resin. Thus, it can be inferred that a strong network of pigment, compound S and the above-mentioned specific resin can be formed in the film. Thus, it can be inferred that a film that is difficult to hydrolyze by a developer can be obtained. In addition, it can be inferred that the specific resin has a specific structure, which can make the dispersion state of the pigment in the film good, and can make the phase structure of the film uniform. Therefore, it can be inferred that the penetration path of the developer of the film is uniform, and as a result, it can be suppressed that the developer locally penetrates into the film to produce defects. For these reasons, it can be inferred that pixels with excellent developer resistance can be formed by using the coloring composition of the present invention.

[0100] Furthermore, it is presumed that the exposure latitude can be expanded by making the phase structure of the film uniform.

[0101] In particular, compound S easily interacts with a pigment having a metal atom, and when a pigment having a metal atom is used, a pixel having better developer resistance can be formed. In particular, when an azomethine metal complex or a phthalocyanine metal complex is used as the pigment, a better effect can be exerted.

[0102] The coloring composition of the present invention can be preferably used as a coloring composition for color filters or infrared transmission filters. More specifically, it can be preferably used as a coloring composition for forming pixels of color filters or a coloring composition for forming infrared transmission filters, and can be more preferably used as a coloring composition for forming pixels of color filters.

[0103] Furthermore, the coloring composition of the present invention can be preferably used as a solid-state imaging element, and more specifically, can be preferably used as a coloring composition for forming pixels of a color filter or a coloring composition for forming an infrared transmission filter used in a solid-state imaging element.

[0104] When the coloring composition of the present invention is used to form a film with a thickness of 0.65 μm, the wavelength at which the transmittance of the film becomes 50% is preferably present in the wavelength range of 470 to 520 nm, more preferably in the wavelength range of 475 to 520 nm, and further preferably in the wavelength range of 480 to 520 nm. Among them, the wavelength at which the transmittance becomes 50% is preferably present in the wavelength range of 470 to 520 nm and in the wavelength range of 575 to 625 nm, respectively. In this mode, the wavelength on the short wavelength side at which the transmittance becomes 50% is preferably present in the wavelength range of 475 to 520 nm, and more preferably in the wavelength range of 480 to 520 nm. And, the wavelength on the long wavelength side at which the transmittance becomes 50% is preferably present in the wavelength range of 580 to 620 nm, and more preferably in the wavelength range of 585 to 615 nm. A coloring composition capable of forming a film having such spectral characteristics can be preferably used as a coloring composition for forming green pixels of a color filter.

If the average primary particle size of the pigment is within the above range, the dispersion stability of the pigment in the coloring composition is good. In addition, in the present invention, the primary particle size of the pigment can be observed by a transmission electron microscope and obtained from the photographs obtained. Specifically, the projected area of ​​the primary particles of the pigment is obtained, and the corresponding circle equivalent diameter is calculated as the primary particle size of the pigment.

[0479] <Method for producing film>

[0480] Next, the method for producing the film of the present invention is described. The film of the present invention can be produced by applying the coloring composition of the present invention. In the method for producing the film, it is preferred that the step of forming a pattern (pixel) is also included. As a method for forming a pattern (pixel), photolithography and dry etching can be cited. Considering that the coloring composition of the present invention has excellent exposure latitude, it is particularly excellent when the pattern is formed by photolithography.

[0481] The pattern formation based on the photolithography method preferably includes the following steps: a step of forming a colored composition layer on a support using the colored composition of the present invention; a step of exposing the colored composition layer to a pattern; and a step of developing and removing the unexposed portion of the colored composition layer to form a pattern (pixel). If necessary, a step of baking the colored composition layer (pre-baking step) and a step of baking the developed pattern (pixel) (post-baking step) may also be provided.

[0482] In the process of forming the colored composition layer of the present invention, a colored composition layer is formed on a support using a colored composition. As a support, there is no particular limitation and it can be appropriately selected according to the purpose. For example, a glass substrate, a silicon substrate, etc. can be cited, preferably a silicon substrate. In addition, a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), a transparent conductive film, etc. can be formed on the silicon substrate. In addition, a black matrix is ​​sometimes formed on the silicon substrate to isolate each pixel. In addition, in order to improve the adhesion with the upper layer, prevent the diffusion of substances, or flatten the surface of the substrate, a base layer can be provided on the silicon substrate. The base layer can also be formed using a composition in which a colorant is removed from the colored composition described in this specification or a composition containing a curable compound, a surfactant, etc. described in this specification. The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane. And, it is preferably 30 to 80° when measured with water. If the surface contact angle of the base layer is within the above range, the wettability of the colored composition is good. The adjustment of the surface contact angle of the base layer can be carried out, for example, by methods such as the addition of a surfactant.

[0483] As a coating method of the coloring composition, a known method can be used. For example, a dropping method (droplet coating); a slit coating method; a spray method; a roll coating method; a spin coating method (spin coating); a cast coating method; a slit spin coating method; a pre-wetting method (for example, the method described in Japanese Patent Application Publication No. 2009-145395); various printing methods such as inkjet (for example, on-demand method, piezoelectric method, thermal method), nozzle jetting, etc., flexographic printing, screen printing, gravure printing, reverse offset printing, metal mask printing method, etc.; a transfer method using a mold, etc.; a nanoimprint method, etc. The application method in inkjet is not particularly limited, and examples thereof include the method described in "Inkjet that can be promoted and used - Infinite possibilities appearing in patents -, published in February 2005, Sumitbe Techon Research Co., Ltd."

[0484] The colored composition layer formed on the support can be dried (prebaked). In the case of manufacturing the film by a low-temperature process, prebaking may not be performed. When prebaking is performed, the prebaking temperature is preferably below 150°C, more preferably below 120°C, and further preferably below 110°C.

The prebaking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and further preferably 80 to 220 seconds. Prebaking can be performed using a hot plate, an oven, or the like.

[0485] Next, the colored composition layer is exposed in a pattern (exposure step). For example, a stepper, a scanner, or the like is used to expose the colored composition layer through a mask having a predetermined mask pattern, thereby exposing the colored composition layer in a pattern. Thus, the exposed portion can be cured.

[0486] As radiation (light) that can be used for exposure, g-rays, i-rays, etc. can be cited. In addition, light with a wavelength of 300nm or less (preferably light with a wavelength of 180 to 300nm) can also be used. As light with a wavelength of 300nm or less, KrF rays (wavelength 248nm), ArF rays (wavelength 193nm), etc. can be cited, preferably KrF rays (wavelength 248nm). In addition, a light source with a long wavelength of 300nm or more can also be used.

[0487] Furthermore, during exposure, the light may be continuously irradiated for exposure or pulsed for exposure (pulse exposure). In addition, pulse exposure refers to an exposure method in which light is irradiated and paused repeatedly in a short-time (e.g., less than millisecond level) cycle for exposure.

[0488] The irradiation amount (exposure amount) is preferably, for example, 0.03 to 2.5 J / cm 2 , more preferably 0.05 to 1.0 J / cm 2 The oxygen concentration during exposure can be appropriately selected. In addition to exposure under the atmosphere, exposure can be performed in a low oxygen environment with an oxygen concentration of 19% by volume or less (e.g., 15% by volume, 5% by volume, or substantially oxygen-free), or in a high oxygen environment with an oxygen concentration exceeding 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). Furthermore, the exposure illuminance can be appropriately set, and can generally be set from 1000 W / m 2 ~100000W / m 2 (For example, 5000W / m 2 , 15000W / m 2 or 35000W / m 2 The oxygen concentration and exposure illuminance can be appropriately combined, for example, the oxygen concentration can be set to 10% by volume and the illuminance can be set to 10000 W / m2 , oxygen concentration 35 volume % and illumination 20000W / m 2 wait.

[0489] Next, the unexposed portion of the colored composition layer is removed by development to form a pattern (pixel). The development and removal of the unexposed portion of the colored composition layer can be performed using a developer. As a result, the unexposed portion of the colored composition layer in the exposure process is dissolved in the developer, and only the photocured portion remains. The temperature of the developer is preferably 20 to 30° C., for example. The development time is preferably 20 to 180 seconds. In addition, in order to improve the removability of the residue, the process of shaking off the developer every 60 seconds and then supplying a new developer can be repeated multiple times.

[0490] The developer may include organic solvents, alkaline developers, etc., and an alkaline developer may be preferably used. As the alkaline developer, an alkaline aqueous solution (alkaline developer) obtained by diluting an alkaline agent with pure water is preferred. As the alkaline agent, for example, organic alkaline compounds such as ammonia, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxylamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, pyrrole, piperidine, 1,8-diazabicyclo-[5.4.0]-7-undecene, or inorganic alkaline compounds such as sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, and sodium metasilicate may be mentioned. In terms of environment and safety, the alkaline agent is preferably a compound with a large molecular weight. The concentration of the alkaline agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. Furthermore, the developer may further contain a surfactant. From the perspective of convenient transportation or storage, the developer can be temporarily manufactured into a concentrated solution and diluted to the desired concentration when used. The dilution ratio is not particularly limited, for example, it can be set in the range of 1.5 to 100 times. Furthermore, it is also preferred to wash (rinse) with pure water after development. Furthermore, it is preferred to rotate the support on which the developed colored composition layer has been formed and to supply a rinsing liquid to the developed colored composition layer for rinsing. Furthermore, it is also preferred to move the nozzle that spits out the rinsing liquid from the center of the support to the peripheral portion of the support. At this time, when the nozzle moves from the center of the support to the peripheral portion, it can be moved while gradually reducing the moving speed of the nozzle. By rinsing in this way, the in-plane deviation of the rinsing can be suppressed. Furthermore, the same effect can be obtained by gradually reducing the rotation speed of the support while moving the nozzle from the center of the support to the peripheral portion.

[0491] Preferably, after development, additional exposure treatment and heating treatment (post-baking) are performed after drying. Additional exposure treatment and post-baking are curing treatments after development for making a completely cured material. The heating temperature in the post-baking is preferably 100 to 240°C, more preferably 200 to 240°C, for example. The developed film can be post-baked in a continuous or intermittent manner using a heating mechanism such as a heating plate or a convection oven (hot air circulation dryer), a high-frequency heater, etc. in a manner that achieves the above conditions. In the case of performing additional exposure treatment, the light used for exposure is preferably light with a wavelength of less than 400nm. In addition, the additional exposure treatment can be performed by the method described in Korean Patent Gazette No. 10-2017-0122130.

[0492] The pattern formation based on the dry etching method preferably includes the following steps: forming a colored composition layer on a support using the colored composition of the present invention, and curing the entire colored composition layer to form a cured layer; forming a photoresist layer on the cured layer; exposing the photoresist layer to a pattern, and then developing to form a resist pattern; and using the resist pattern as a mask and using an etching gas to dry-etch the cured layer. When forming the photoresist layer, it is preferred to further perform a pre-baking treatment. In particular, as a step for forming the photoresist layer, it is preferred to perform a heat treatment after exposure and a heat treatment after development (post-baking treatment). Regarding the pattern formation using the dry etching method, reference can be made to the records of paragraphs 0010 to 0067 of Japanese Patent Gazette No. 2013-064993, and the content is incorporated into this specification.

[0654] <Production of Colored Pixels>

[0655] A transparent primer (CT-4000L solution, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was applied to a silicon wafer having a diameter of 8 inches (20.32 cm) so that the dry film thickness was 0.1 μm, and after drying to form a base layer, a heat treatment was performed at 220°C for 5 minutes to obtain a silicon wafer with a base layer. Next, the coloring compositions of the examples and comparative examples prepared as described above were applied to the base layer of the silicon wafer with a base layer, respectively, to form a coloring composition layer (coating film). Moreover, a heating treatment (pre-baking) was performed for 120 seconds using a hot plate at 100°C so that the dry film thickness of the coating film was 0.5 μm. Next, an i-ray stepper exposure device FPA-3000i5+ (manufactured by Canon Inc.) was used to expose the film at 50 to 1200 mJ / cm through a 0.9 μm square Island pattern mask. 2 The silicon wafer formed with the irradiated coating film was exposed to light of a wavelength of 365 nm at various exposure amounts. Next, the silicon wafer on which the irradiated coating film was formed was placed on a horizontal turntable of a rotary spray developer (DW-30 model, manufactured by CHEMITRONICS CO., Ltd.), and a developer (CD-2000, manufactured by FUJIFILM F1ectronic Materials Co., Ltd.) was used to perform spin immersion development at 23°C for 60 seconds. Next, the silicon wafer on which the film after spin immersion development was formed was fixed to a horizontal turntable by a vacuum chuck method, and the silicon wafer was rotated at a rotation speed of 50 rpm by a rotating device while pure water was supplied from a spray nozzle from above its rotation center in a spray state for rinsing treatment, and then spray drying was performed. Next, a heating treatment (post-baking) was performed at 200°C for 300 seconds using a hot plate to form a colored pixel.

[0656] As described above, a single-color color filter having colored pixels formed using the colored composition of the example or the comparative example was produced.

[0657] Then, the line width of the colored pixels was measured using a length-measuring SEM "S-9260A" (manufactured by Hitachi High-Technologies Corporation), and the exposure amount at which the line width of the colored pixels became 1.2 μm was determined as the most preferable exposure amount.

[0658] (Performance evaluation) [Evaluation of exposure latitude]

[0659] In the production of the above colored pixels, the exposure amount is changed to 10 to 500 mJ / cm 2The exposure was performed at various exposure levels, and the exposure width of the colored pixel line width after post-bake was found to be 0.9μm±10%. This value was divided by the above-mentioned optimal exposure and the value expressed as a percentage (%) was evaluated as the exposure latitude. If it is A to C, it is a level with no practical problems.

[0660] A: The exposure latitude value is above 15%.

[0661] B: The exposure latitude value is 12% or more and less than 15%.

[0662] C: The exposure latitude value is 9% or more and less than 12%.

[0663] D: The exposure latitude value is less than 9%.

[0664] [Evaluation of developer resistance]

[0665] In the production of the above colored pixels, the cross-section of the colored pixels produced by exposure to an exposure amount of 0.9 μm was observed after 20 baking, and the number of colored pixels having holes of 0.001 μm or more was counted to evaluate the developer resistance. If it is A or B, it is a level with no practical problem.

[0666] A: The number of colored pixels having holes with a diameter of 0.001 μm or more is 0.

[0667] B: The number of colored pixels having holes with a diameter of 0.001 μm or more is 1 to 3.

[0668] C: The number of colored pixels having pores with a diameter of 0.001 μm or more is 3 or more.

[0673] As shown in the above table, all of the Examples were excellent in developer resistance.

[0674] The coloring compositions of Examples 13, 22, and 29 were spin-coated on a glass substrate and pre-baked at 90° C. for 120 seconds to obtain a coating film with a thickness of 2.0 μm. 2The cured film was prepared by irradiating with light with an exposure amount of 100 μg (i-ray conversion) and then baking in an oven at 120°C for 60 minutes. The cured film was rubbed 10 times with steel wool #0000 with a load of 500 g and visually observed to find no scratches and excellent scratch resistance.

[0675] Regarding the colored composition of Example 73, a 0.8 μm square island pattern mask was used to form colored pixels with a finer line width, and the exposure latitude and developer resistance were evaluated. Both were A, showing good results.

[0676] (Example 101)

[0677] In the colored composition of Example 1, a colored composition of Example 101 was produced in the same manner as in Example 1, except that the photopolymerization initiator I-1 was changed to a thermal polymerization initiator (t-butyl perbenzoate).

[0678] <Evaluation of developer resistance>

[0679] The coloring composition of Example 101 was applied to a glass wafer using a spin coater to form a coating film with a thickness of 0.6 μm, and then dried at 100°C for 180 seconds using a hot plate, and then heated (post-baked) at 200°C for 300 seconds to form a coloring layer. The thickness of the coloring layer was 0.6 μm. Next, a positive photoresist (FHi622BC, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was applied to the coloring layer and pre-baked to form a photoresist layer with a thickness of 0.8 μm. Next, an i-ray stepper (manufactured by Canon Inc.) was used at 350 mJ / cm 2 The photoresist layer was pattern-exposed with an exposure amount of , and a heating treatment was performed for 1 minute at a temperature at which the temperature of the photoresist layer or the ambient temperature reached 90°C. After that, a developing solution (FHD-5, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was used for a 1-minute development treatment, and then a post-baking treatment was performed at 110°C for 1 minute to form a photoresist pattern. The photoresist pattern is a pattern in which a square-shaped resist film formed by 0.9 μm on one side is arranged in a grid shape in consideration of the etching conversion difference (reduction of the pattern width caused by etching). Next, the photoresist pattern was used as an etching mask, and the coloring layer was dry-etched in the following order.

[0680] The dry etching apparatus (U-621 manufactured by Hitachi High-Technologies Corporation) was used with RF power of 800 W, antenna bias of 400 W, wafer bias of 200 W, chamber internal pressure of 4.0 Pa, substrate temperature of 50° C., and gas type and flow rate of the mixed gas set to CF 4 :80mL / min.、O 2 : 40 mL / min., Ar: 800 mL / min., and the first-stage etching process was performed for 80 seconds.

[0681] Next, the same etching chamber was used with RF power of 600 W, antenna bias of 100 W, wafer bias of 250 W, chamber internal pressure of 2.0 Pa, substrate temperature of 50 °C, and gas type and flow rate of the mixed gas set to N 2 :500mL / min.、O 2 :50mL / min., Ar:500mL / min.(N 2 / O 2 / Ar=10 / 1 / 10), the over-etching rate in the total etching amount was set to 20%, and the second stage etching process and the over-etching process were carried out for 20 seconds.

[0682] After dry etching under the above conditions, a photoresist stripping solution (MS230C, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was used to perform a stripping process for 120 seconds to remove the photoresist pattern, and then a pure water-based cleaning and spin drying were performed. After that, a dehydration baking process was performed at 100°C for 2 minutes. Through the above, a coloring pattern in which square-shaped coloring pixels (coloring pixels with a line width of 0.9 μm) with a side of 0.9 μm were arranged in a grid shape was obtained.

[0683] The silicon wafer with the colored pattern formed thereon was placed on a horizontal turntable of a rotary spray developer (DW-30 model, manufactured by CHEMITRO NICSCO., Ltd.), and a developer (CD-2000, manufactured by FUJIFILM Electronic Materials Co., Ltd.) was used to perform a spin immersion development at 23°C for 60 seconds to perform a development process. After that, the silicon wafer substrate was fixed to the horizontal turntable by a vacuum chuck, and the silicon wafer substrate was rotated at a rotation speed of 50 rpm by a rotating device while pure water was supplied from a spray nozzle from above the rotation center to perform a rinsing process, and then spray drying was performed.

[0684] Regarding the colored pattern after spray drying, developer resistance was evaluated in the same procedure as above. When the colored composition of Example 101 was used, the evaluation result was “A” and good.

[0685] (Example 1001)

[0686] The green coloring composition was applied to a silicon wafer by spin coating so that the film thickness after film formation was 1.0 μm. Then, the film was heated at 100° C. for 2 minutes using a hot plate. Then, an i-ray stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Inc.) was used at 1000 mJ / cm 2 The exposure amount was exposed through a mask with a 2μm square dot pattern. Then, a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH) was used to perform spin immersion development at 23°C for 60 seconds. Then, it was rinsed by spin spraying and further washed with pure water. Next, a hot plate was used to heat at 200°C for 5 minutes, thereby patterning the green coloring composition to form a green pixel. Similarly, the red coloring composition and the blue coloring composition were patterned by the same process to form red pixels and blue pixels in sequence, thereby forming a color filter having green pixels, red pixels and blue pixels. In the color filter, green pixels are formed in a Bayer pattern, and red pixels and blue pixels are formed in an island pattern in the adjacent area. The obtained color filter is embedded in a solid-state imaging element according to a known method. The solid-state imaging element has a preferred image recognition capability. In addition, as a green coloring composition, a coloring composition of Example 50 was used. As a red coloring composition, a coloring composition of Example 53 was used. The blue coloring composition uses a coloring composition manufactured by the following method.
