[0012] <Composition> The composition of the present invention is characterized by comprising a compound represented by formula (1) or formula (2), a curable compound, and a solvent.
[0013] The present invention provides a composition that can form a film with excellent heat resistance and suppressed color transfer. The reasons for these effects are presumed to be as follows.
[0014] The compounds represented by formula (1) or formula (2) have a highly planar structure, and are therefore presumed to readily form associations in the film and have high thermal stability. For this reason, a film with excellent heat resistance can be formed by using the composition of the present invention. Furthermore, it is presumed that the ease with which the compounds form associations in the film suppresses their movement and prevents them from leaching out of the film. For this reason, it is presumed that a film in which color transfer to adjacent films is suppressed can be formed by using the composition of the present invention.
[0015] The composition of the present invention can be used as a composition for forming optical filters. Examples of optical filters include color filters and infrared transmission filters. More specifically, the composition of the present invention can be preferably used as a composition for forming pixels in a color filter or as a composition for forming an infrared transmission filter.

[0203] <Memory manufacturing method> The film of the present invention can be manufactured by a process of applying the composition of the present invention. The manufacturing process of the film may further include a step to form a pattern (pixel). Examples of methods for forming the pattern (pixel) include photolithography and dry etching, with photolithography being preferred.
[0204] The pattern formation by photolithography preferably includes the steps of forming a composition layer on a support using the composition of the present invention, exposing the composition layer in a pattern, and developing and removing the unexposed parts of the composition layer to form a pattern (pixels). If necessary, a step of baking the composition layer (pre-bake step) and a step of baking the developed pattern (pixels) (post-bake step) may be provided.
[0205] In the step of forming the composition layer, the composition layer is formed on a support using the composition of the present invention. The support is not particularly limited and can be appropriately selected depending on the application. Examples include glass substrates and silicon substrates, with silicon substrates being preferred. Charge-coupled devices (CCDs), complementary metal-oxide-semiconductor (CMOS) elements, transparent conductive films, etc., may be formed on the silicon substrate. A black matrix that isolates each pixel may also be formed on the silicon substrate. Furthermore, a base layer may be provided on the silicon substrate to improve adhesion with the upper layer, prevent diffusion of substances, or flatten the substrate surface. The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane. It is also preferably 30 to 80° when measured with water.
[0206] Known methods can be used for coating the composition. For example, drop casting; slit coating; spray coating; roll coating; spin coating; casting; slit and spin coating; pre-wetting (e.g., the method described in Japanese Patent Publication No. 2009-145395); various printing methods such as inkjet (e.g., on-demand, piezo, thermal), nozzle jet printing, flexographic printing, screen printing, gravure printing, reverse offset printing, and metal mask printing; transfer methods using molds, etc.; and nanoimprint methods. In addition, the coating method described in paragraph 0207 of International Publication No. 2022 / 085485 can also be used.
[0207] The composition layer formed on the support may be dried (pre-baked). Pre-baking is not necessary when manufacturing the film by a low-temperature process. If pre-baking is performed, the pre-baking temperature is preferably 150°C or lower, more preferably 120°C or lower, and even more preferably 110°C or lower. The lower limit can be, for example, 50°C or higher, and also 80°C or higher. The pre-baking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and even more preferably 80 to 220 seconds. Pre-baking can be performed using a hot plate, oven, etc.
[0208] Next, the composition layer is exposed in a pattern (exposure step). For example, the composition layer can be exposed in a pattern by using a stepper exposure machine or a scanner exposure machine to expose it through a mask having a predetermined mask pattern. This allows the exposed areas to be cured.
[0209] Examples of radiation (light) that can be used during exposure include g-rays and i-rays. Light with a wavelength of 300 nm or less (preferably light with a wavelength of 180 to 300 nm) can also be used. Examples of light with a wavelength of 300 nm or less include KrF rays (wavelength 248 nm) and ArF rays (wavelength 193 nm), with KrF rays (wavelength 248 nm) being preferred. Long-wave light sources with wavelengths of 300 nm or more can also be used.
[0210] Furthermore, exposure may be performed by continuously irradiating with light, or by irradiating in pulses (pulsed exposure). Pulsed exposure is an exposure method that involves repeatedly irradiating and pausing with light in short cycles (for example, at the millisecond level or less).
[0211] The irradiation dose (exposure dose) is, for example, 0.03 to 2.5 J / cm². 2 Preferably, 0.05 to 1.0 J / cm² 2 This is more preferable. The oxygen concentration during exposure can be appropriately selected. In addition to exposure in air, exposure may be carried out in a low-oxygen atmosphere with an oxygen concentration of 19 vol% or less (e.g., 15 vol%, 5 vol%, or substantially oxygen-free), or in a high-oxygen atmosphere with an oxygen concentration exceeding 21 vol% (e.g., 22 vol%, 30 vol%, or 50 vol%). Furthermore, the exposure intensity can be appropriately set, usually 1000 W / m². 2 ~100,000 W / m 2 (For example, 5000W / m 2 , 15000W / m 2 , or 35000W / m 2The oxygen concentration and exposure intensity can be combined as appropriate; for example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m². 2 At an oxygen concentration of 35% by volume, the illuminance is 20,000 W / m². 2 This can be done as follows.
[0212] Next, the unexposed areas of the composition layer are developed and removed to form a pattern (pixels). The development and removal of the unexposed areas of the composition layer can be done using a developer. This causes the unexposed areas of the composition layer in the exposure process to dissolve in the developer, leaving only the photocured parts. The temperature of the developer is preferably, for example, 20 to 30°C. The development time is preferably 20 to 180 seconds. In addition, to improve the ability to remove residue, the developer may be emptied every 60 seconds, and the process of supplying fresh developer may be repeated several times.
[0213] Examples of developing solutions include organic solvents and alkaline developers, with alkaline developers being preferred. For the developing solution and the rinsing method after development, the developing solution and rinsing method described in paragraph 0214 of International Publication No. 2022 / 085485 may be used.
[0214] After development and drying, it is preferable to perform additional exposure or heat treatment (post-bake). Additional exposure and post-bake are curing treatments after development to ensure complete hardening. The heating temperature in post-bake is preferably 100 to 300°C, and more preferably 100 to 270°C. Post-bake can be performed continuously or in batches using heating means such as a hot plate, convection oven (hot air circulation dryer), or high-frequency heater to achieve the above conditions. When performing additional exposure, it is preferable that the light used for exposure has a wavelength of 400 nm or less. The additional exposure may also be performed using the method described in Korean Published Patent No. 10-2017-0122130.
[0215] The dry etching method for pattern formation preferably includes the steps of: forming a composition layer on a support using the composition of the present invention; curing the entire composition layer to form a cured layer; forming a photoresist layer on the cured layer; exposing the photoresist layer in a patterned manner, then developing it to form a resist pattern; and using the resist pattern as a mask to dry etch the cured layer using an etching gas. In the formation of the photoresist layer, it is preferable to further perform a pre-bake treatment. In particular, the photoresist layer formation process is preferably one in which a heat treatment after exposure and a heat treatment after development (post-bake treatment) are performed. For the dry etching method for pattern formation, refer to paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, and this content is incorporated herein by reference.

The configuration of the solid-state image sensor is not particularly limited as long as it has the film of the present invention and functions as a solid-state image sensor. For example, the following configurations can be considered.
[0217] The imaging device has a support on which a plurality of photodiodes constituting the light-receiving area of a solid-state image sensor and a transfer electrode made of polysilicon or the like are provided. The photodiodes and transfer electrode have a light-shielding film made of tungsten or the like with an opening only for the light-receiving portion of the photodiode. The light-shielding film has a device protection film made of silicon nitride or the like formed to cover the entire surface of the light-shielding film and the light-receiving portion of the photodiode.

The color filter may also have a structure in which a film forming each 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 lower refractive index than each pixel. Examples of imaging devices having such a structure include the devices described in Japanese Patent Application Publication No. 2012-227478 and Japanese Patent Application Publication No. 2014-179577.

[0274] (Method for evaluating color transfer properties) A color transfer evaluation composition is applied to a soda glass substrate with an SiO2 film formed on its surface using a spin coater. The substrate is then pre-baked on a 90°C hot plate for 2 minutes to form a 2.4 μm thick coating. After the substrate is cooled to room temperature, a high-pressure mercury lamp is used to expose the coating to radiation at 400 J / m², without a photomask, including wavelengths of 365 nm, 405 nm, and 436 nm. 2 The entire substrate is exposed to light. Then, a developer consisting of a 0.04 mass% potassium hydroxide aqueous solution at 23°C is applied to the substrate at a developing pressure of 1 kgf / cm². 2 The material is extruded using a nozzle with a diameter of 1 mm. After that, the substrate is washed with ultrapure water, air-dried, and then post-baked in a clean oven at 230°C for 30 minutes to produce a monochromatic filter. The resulting monochromatic filter is measured using a color analyzer (LCF-1100A, manufactured by Otsuka Electronics Co., Ltd.) with a C light source and a 2-degree field of view to measure the stimulus value (Y), i.e., luminance, in the CIE color system. This luminance is denoted as "YR".
[0275] The compositions of each example and comparative example are applied to a soda glass substrate with an SiO2 film formed on its surface using a spin coater, and then pre-baked on a 90°C hot plate for 2 minutes to form a coating with a thickness of 2.4 μm. After the substrate is cooled to room temperature, radiation including wavelengths of 365 nm, 405 nm, and 436 nm is applied to the coating using a high-pressure mercury lamp via a photomask at a rate of 400 J / m². 2 The substrate is exposed to light at the specified exposure level. Next, a developer solution consisting of a 0.04 mass% potassium hydroxide aqueous solution at 23°C is applied to the substrate at a developing pressure of 1 kgf / cm². 2 The substrate is extruded using a nozzle with a diameter of 1 mm and shower-developed for 90 seconds. After that, the substrate is washed with ultrapure water, air-dried, and then post-baked in a clean oven at 230°C for 30 minutes to produce a substrate with a first filter having a roughly square shape of 3 cm x 3 cm. Next, the color transfer evaluation composition is applied to the substrate on which the first filter is formed using a spin coater, and then pre-baked on a 90°C hot plate for 2 minutes to form a coating film with a thickness of 2.4 μm. After the substrate is cooled to room temperature, radiation including wavelengths of 365 nm, 405 nm, and 436 nm is applied to the coating film at a rate of 400 J / m² using a high-pressure mercury lamp without a photomask. 2 The entire substrate is exposed to light. A developer consisting of a 0.04 mass% potassium hydroxide aqueous solution at 23°C is then applied to the substrate at a developing pressure of 1 kgf / cm². 2 The material is extruded using a nozzle with a diameter of 1 mm. After that, the substrate is washed with ultrapure water, air-dried, and then post-baked in a clean oven at 230°C for 30 minutes to produce a substrate with a second filter on top of the first filter.
[0276] At a point 200 μm away from the interface where the first and second filters of the above substrate overlap, in the direction of non-overlap, a color analyzer (LCF-1100A, manufactured by Otsuka Electronics Co., Ltd.) is used to measure the stimulus value (Y) of the second filter in the CIE color system, i.e., luminance, using a C light source and a 2-degree field of view. This luminance is denoted as "Y1". The rate of change in brightness is calculated using the following formula, and the color transfer properties are evaluated. Rate of change in brightness (%) = ((YR - Y1) / YR) × 100 A: Brightness change rate is less than 2.0% B: Luminance change rate is 2.0% or more and less than 4.0% C: Brightness change rate is 4.0% or higher

[0279] <Evaluation of coloring properties> For films obtained using the compositions of Examples 1-6 and Comparative Example 1, the absorption spectra in the wavelength range of 400-700 nm were measured using a spectrophotometer (U-4100, Hitachi High-Tech Corporation), and the average transmittance in the range of the maximum absorption wavelength λmax ± 25 nm was calculated. The coloring power was then evaluated according to the following criteria: A lower average transmittance in the range of the maximum absorption wavelength λmax ± 25 nm indicates higher coloring power. A: Average transmittance ≤ 10% in the range of maximum absorption wavelength λmax ± 25 nm B: 10% < Average transmittance in the range of maximum absorption wavelength λmax ± 25nm ≤ 20% C: 20% < Average transmittance in the range of maximum absorption wavelength λmax ± 25 nm
