Description

[Technical Field]

[0001] The present invention relates to a composition containing a near-infrared absorbing dye. Furthermore, the present invention relates to a film, optical filter, solid-state image sensor, image display device, infrared sensor, and camera module using a composition containing a near-infrared absorbing dye. The present invention also relates to a near-infrared absorbing dye. [Background technology]

[0002] Optical filters, such as infrared cut filters, are manufactured using compositions containing near-infrared absorbing dyes.

[0003] Examples of near-infrared absorbing dyes include squarylium compounds. Patent document 1 describes forming an optical filter, such as an infrared cut filter, using a composition containing a near-infrared absorbing dye represented by formula (A). [ka] [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] International Publication No. 2019 / 230660 [Overview of the project] [Problems that the invention aims to solve]

[0005] Generally, extending the absorption wavelength of near-infrared absorbing dyes requires lengthening the conjugated system. Patent Document 1 also describes how a bisthiophene ring is introduced into tetraangic acid to extend the conjugated length.

[0006] However, as the conjugated system of near-infrared absorbing dyes was extended, it tended to aggregate easily, leading to a higher likelihood of foreign body defects occurring within the film.

[0007] Therefore, an object of the present invention is to provide a composition capable of forming a film in which the generation of foreign matter defects is suppressed. Another object of the present invention is to provide a film, an optical filter, a solid-state imaging device, an image display device, an infrared sensor, a camera module, and a near-infrared absorbing dye.

[0013] <Composition> The composition of the present invention, A near-infrared absorbing dye having an inclusion compound structure a1 in which a compound represented by formula (1) is the guest and a cyclic compound that encloses the aforementioned guest is the host, or an inclusion compound structure a2 in which a compound having a dye structure derived from the compound represented by formula (1) is the guest and a cyclic compound that encloses the dye structure of the aforementioned guest is the host, Curable compounds and It is characterized by containing a solvent.

[0014] The composition of the present invention can form a film in which the occurrence of foreign matter defects is suppressed. The compound represented by formula (1) has an expanded conjugated aromatic ring, and is therefore prone to aggregation and generation of foreign matter due to interactions between aromatic rings. However, the near-infrared absorbing dye used in the composition of the present invention has the aforementioned inclusion compound structure a1 or inclusion compound structure a2, which is presumed to suppress aggregation of the guest compound represented by formula (1) or the compound having a dye structure derived from the compound represented by formula (1) by causing steric hindrance to the host cyclic compound. For this reason, the composition of the present invention is presumed to be able to form a film in which the generation of foreign matter defects is suppressed.

[0015] The composition of the present invention can be used as a composition for optical filters. Examples of optical filters include infrared cut filters and infrared transmission filters.

[0016] The following describes each component used in the composition of the present invention.

[0017] <<Specific near-infrared absorbing dyes>> The composition of the present invention includes a near-infrared absorbing dye (hereinafter also referred to as a specific near-infrared absorbing dye) having an inclusion compound structure a1 in which a compound represented by formula (1) is a guest and a cyclic compound that encloses the aforementioned guest is a host, or an inclusion compound structure a2 in which a compound having a dye structure derived from a compound represented by formula (1) is a guest and a cyclic compound that encloses the dye structure of the aforementioned guest is a host. This specific near-infrared absorbing dye is also the near-infrared absorbing dye of the present invention.

[0018] In this specification, an inclusion compound structure means that the guest penetrates the internal ring space of the host cyclic compound and integrates with the ring. That is, in the specific near-infrared absorbing dye of the present invention, the guest, which is a compound represented by formula (1) or a compound having a dye structure derived from the compound represented by formula (1), penetrates the internal ring space of the host cyclic compound and integrates with the ring. More specifically, when the guest is a compound represented by formula (1), the compound represented by formula (1) penetrates the internal ring space of the host cyclic compound and integrates with the ring. Also, when the guest is a compound having a dye structure derived from the compound represented by formula (1), the dye structure of the guest penetrates the internal ring space of the host cyclic compound and integrates with the ring. It should be noted that the presence of an inclusion compound structure in a compound can be confirmed by combining thin-layer chromatography with mass spectrometry methods such as Maldi-tof-MS (Matrix-Assisted Laser Desorption / Ionization Time-of-Flight Mass Spectrometry).

The composition of the present invention may not substantially contain perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts. For example, by using compounds that can substitute for perfluoroalkyl sulfonic acid and its salts, and compounds that can substitute for perfluoroalkyl carboxylic acid and its salts, a composition that substantially does not contain perfluoroalkyl sulfonic acid and its salts, and perfluoroalkyl carboxylic acid and its salts may be selected. Compounds that may substitute for regulated compounds include, for example, compounds that have been excluded from regulation due to differences in the number of carbon atoms in the perfluoroalkyl group. However, the above does not preclude the use of perfluoroalkyl sulfonic acids and their salts, and perfluoroalkyl carboxylic acids and their salts. The compositions of the present invention may contain perfluoroalkyl sulfonic acids and their salts, and perfluoroalkyl carboxylic acids and their salts, to the maximum permissible extent.

A film having such spectral characteristics can block light in the wavelength range of 400 to 1050 nm and transmit light with a wavelength greater than 1150 nm.

[0348] The film of the present invention can be used in various devices such as solid-state image sensors (CCDs and CMOSs) (the imaging portion can use compound semiconductors such as InGaAs, organic semiconductors, quantum dots, etc., in addition to Si), infrared sensors, light-emitting elements, optical communication elements (both transmitting and receiving), and image display devices.

[0349] <Memory manufacturing method> The film of the present invention can be manufactured by a process of applying the composition of the present invention.

[0350] Examples of supports include those mentioned above. Known methods such as spin coating can be used for coating the composition. For example, the coating method described in paragraph 0207 of International Publication No. 2022 / 085485 can be used.

[0351] The composition layer formed by applying the composition may be dried (pre-baked). When 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 seconds to 3000 seconds, more preferably 40 to 2500 seconds, and even more preferably 80 to 220 seconds. Drying can be performed using a hot plate, oven, etc.

[0352] The method for manufacturing the film may further include a step of forming a pattern. Examples of pattern formation methods include a pattern formation method using photolithography and a pattern formation method using dry etching, with the pattern formation method using photolithography being preferred. However, if the film of the present invention is used as a flat film, the step of forming a pattern may not be necessary. The step of forming a pattern will be described in detail below.

[0353] (When forming patterns using photolithography) The photolithography method for forming a pattern preferably includes a step of exposing a composition layer formed by coating the composition of the present invention in a patterned manner (exposure step), and a step of developing and removing the unexposed parts of the composition layer to form a pattern (development step). If necessary, a step of baking the developed pattern (post-bake step) may be provided. Each step will be described below.

[0354] In the exposure process, the composition layer is exposed in a pattern. 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.

[0355] 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.

[0356] Furthermore, exposure may be performed by continuously irradiating with light, or by irradiating with light 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).

[0357] The irradiation dose (exposure dose) is, for example, 0.03 to 2.5 J / cm². 2 Preferably, 0.05 to 1.0 J / cm² 2This 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 2 The 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.

[0358] Next, the unexposed portions of the composition layer after exposure are developed and removed to form a pattern. The development and removal of the unexposed portions of the composition layer can be done using a developer. This causes the unexposed portions of the composition layer in the exposure process to dissolve in the developer, leaving only the photocured portions on the support. 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.

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.

[0360] 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 240°C, and more preferably 200 to 240°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 by the method described in Korean Published Patent No. 10-2017-0122130.

[0361] (When forming patterns using the dry etching method) Pattern formation by dry etching can be performed by coating the composition of the present invention onto a support, curing the composition layer to form a cured material layer, then forming a patterned photoresist layer on this cured material layer, and then dry etching the cured material layer using an etching gas with the patterned photoresist layer as a mask. Pre-baking is preferable when forming the photoresist layer. For pattern formation by dry etching, refer to paragraphs 0010 to 0067 of Japanese Patent Application Publication No. 2013-064993, which are incorporated herein by reference.

[0411] <Evaluation of thermal diffusion suppression> Each composition from Examples 1-129 and Comparative Example 1 was applied to a glass wafer by spin coating to a film thickness of 0.5 μm, and then heated on a hot plate at 100°C for 2 minutes to form a composition layer. Next, the resulting composition layer was exposed to 1000 mJ / cm² of light using an i-line stepper exposure apparatus FPA-3000i5+ (manufactured by Canon Corporation) through a mask with a 5.0 μm square pattern. 2 The image is exposed to light. Next, the exposed composition layer is shower-developed at 23°C for 60 seconds using a 0.3% by mass aqueous solution of tetramethylammonium hydroxide (TMAH) as the developer. After that, it is rinsed with pure water using a spin shower to form a 5 μm square pattern (pixel 1). Next, a pattern (pixel 2) is formed on the glass wafer on which pixel 1 is formed, using a thermal diffusion test composition and the same method, in the gaps of pixel 1. The transmittance (spectroscopy 1) of pixel 2 in the wavelength range of 700 to 1200 nm is measured using a microscopy system (LVmicro V, manufactured by LambdaVision, Inc.). Subsequently, the glass wafer on which pixels 1 and 2 are formed is heated at 260°C for 5 minutes using a hot plate in an air atmosphere. Then, the transmittance (spectroscopy 2) of pixel 2 in the wavelength range of 700 to 1200 nm is measured using a microscopy system (LVmicro V, manufactured by LambdaVision, Inc.). The maximum change in transmittance was determined using Spectrum 1 and Spectrum 2 of pixel 2, and the thermal diffusion suppression was evaluated according to the following criteria. The maximum change in transmittance refers to the change at the wavelength in which the change in transmittance of pixel 2 before and after heating is greatest in the wavelength range of 700 to 1200 nm. -Evaluation Criteria- A: The maximum change in transmittance is less than 2%. B: The maximum change in transmittance is between 2% and 3%. C: The maximum change in transmittance is between 3% and 4%. D: The maximum change in transmittance is between 4% and 5%.
