Abstract
Description
[Technical Field]
[0001] The present invention relates to an indigo compound and a composition containing the same. The present invention also relates to a film, an optical filter, a solid-state imaging device, an image display device, an infrared sensor, and a camera module using a composition containing an indigo compound. [Background technology]
[0002] Video cameras, digital still cameras, and mobile phones with camera functions use solid-state image sensors for color imaging, such as CCDs (charge-coupled devices) and CMOSs (complementary metal-oxide semiconductors). These solid-state image sensors use silicon photodiodes that are sensitive to infrared light in their light receiving section. For this reason, an infrared cut filter is sometimes used to correct visibility.
[0003] Infrared cut filters are produced using compositions containing infrared absorbers, such as indigo compounds.
[0004] Patent Document 1 describes the production of an infrared cut filter or the like using a composition containing a specific indigo boron compound. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-224593 Summary of the Invention [Problem to be solved by the invention]
[0006] In recent years, there has been a demand for further improvement in moisture resistance of films obtained using compositions containing infrared absorbers.
[0007] Furthermore, indigo boron compounds have a high degree of planarity and therefore have a strong cohesive force, which tends to cause aggregation in the film and defects in the film.
[0008] According to the investigations of the present inventors, it has been found that the film obtained using the composition containing the indigo boron compound disclosed in Patent Document 1 is prone to defects in the film. Furthermore, the moisture resistance is also insufficient.
[0009] Therefore, an object of the present invention is to provide a composition capable of forming a film having excellent moisture resistance and suppressing the occurrence of defects. The present invention also provides a film, an optical filter, a solid-state imaging device, an image display device, an infrared sensor, a camera module, and a compound.

[0014] The present invention will be described in detail below. In this specification, the symbol "to" is used to mean that the numerical values before and after it are included as the lower limit and upper limit. In the description of groups (atomic groups) in this specification, when a notation does not specify whether they are substituted or unsubstituted, it encompasses both unsubstituted groups (atomic groups) and substituted groups (atomic groups). For example, the term "alkyl group" encompasses not only alkyl groups without a substituent (unsubstituted alkyl groups) but also alkyl groups with a substituent (substituted alkyl groups). In this specification, unless otherwise specified, "exposure" includes not only exposure using light but also drawing using particle beams such as electron beams and ion beams. Examples of light used for exposure include the bright line spectrum of a mercury lamp, far ultraviolet light typified by excimer lasers, extreme ultraviolet light (EUV light), X-rays, electron beams, and other actinic rays or radiation. In this specification, "(meth)acrylate" refers to either or both of acrylate and methacrylate, "(meth)acrylic" refers to either or both of acrylic and methacrylic, and "(meth)acryloyl" refers to either or both of acryloyl and methacryloyl. In this specification, the weight average molecular weight and number average molecular weight are defined as values converted into polystyrene by gel permeation chromatography (GPC) measurement. In this specification, Me in the chemical formulas represents a methyl group, Et represents an ethyl group, Bu represents a butyl group, and Ph represents a phenyl group. In this specification, infrared rays refer to light (electromagnetic waves) with a wavelength of 700 to 2500 nm. In this specification, the total solid content refers to the total mass of all components of the composition excluding the solvent. In this specification, the term "process" includes not only an independent process but also a process that cannot be clearly distinguished from other processes as long as the intended effect of the process is achieved.
[0015] <Composition> The composition of the present invention is characterized by containing a compound represented by formula (1) or formula (2), a curable compound, and a solvent.
[0016] The composition of the present invention can form a film that has excellent moisture resistance and is suppressed from generating defects. The reason for this effect is presumed to be as follows. The compound represented by formula (1) or formula (2) contained in the composition of the present invention is X in formula (1). 1 and X 2 and at least one of X in formula (2). 11 and X 12At least one of the groups represented by formula (X-1) is an aryl or heteroaryl group having a substituent at the ortho position, which is presumably due to high steric hindrance around the boron atom and the resulting low susceptibility to nucleophilic attack on the boron atom. Therefore, it is presumed that the formation of boron-free products can be suppressed, thereby suppressing the occurrence of defects due to the boron-free products. Therefore, it is presumed that the use of the composition of the present invention can form a film in which defects are suppressed. Furthermore, it is presumed that the compounds represented by formula (1) or (2) have high steric hindrance around the boron atom, making nucleophilic attack on the boron atom less likely to occur, thereby suppressing hydrolysis of the compounds. Therefore, the films obtained using the compositions of the present invention have excellent moisture resistance and can suppress fluctuations in spectroscopic properties even when exposed to a humid environment for a long period of time.
[0017] The composition of the present invention can be used as a composition for an optical filter. Types of optical filters include infrared cut filters and infrared transmission filters. Since the compound represented by formula (1) or formula (2) has excellent visible light transmittance and infrared shielding properties, the composition of the present invention is particularly preferably used as a composition for an infrared cut filter.

When the film of the present invention is used as an infrared cut filter and is used in combination with the film of the present invention and a color filter, it is preferable that the color filter is arranged on the optical path of the film of the present invention. For example, it is preferable that the film of the present invention and a color filter are laminated together to form a laminate.

[0203] <Membrane manufacturing method> The film of the present invention can be produced through a step of applying the composition of the present invention.
[0204] Examples of the support include those described above. As a method for applying the composition, known methods such as spin coating can be used. For example, the application method described in paragraph 0207 of International Publication No. 2022 / 085485 can be used.

When prebaking is performed, the prebaking 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, or can be 80°C or higher. The prebaking time is preferably 10 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, an oven, or the like.
[0206] The film manufacturing method may further include a step of forming a pattern. Examples of the pattern forming method include a pattern forming method using a photolithography method and a pattern forming method using a dry etching method, and a pattern forming method using a photolithography method is preferred. Note that when the film of the present invention is used as a flat film, the step of forming a pattern does not need to be performed. The step of forming a pattern will be described in detail below.
[0207] (When forming patterns using photolithography) The pattern formation method by photolithography preferably includes a step of patternwise exposing a composition layer formed by applying the composition of the present invention (exposure step), and a step of developing and removing the unexposed portions of the composition layer to form a pattern (development step). If necessary, a step of baking the developed pattern (post-baking step) may be provided. Each step will be described below.
[0208] In the exposure step, the composition layer is exposed to light in a pattern. For example, the composition layer can be exposed to light in a pattern by using a stepper exposure machine, a scanner exposure machine, or the like, through a mask having a predetermined mask pattern. This allows the exposed portion to be cured.
[0209] Examples of radiation (light) that can be used for 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, the exposure may be performed by continuous irradiation with light or by pulsed irradiation (pulse exposure), which is an exposure method in which light irradiation and pauses are repeated in short cycles (for example, milliseconds or less).
[0211] The irradiation amount (exposure amount) is, for example, 0.03 to 2.5 J / cm 2 is preferable, and 0.05 to 1.0 J / cm 2 The oxygen concentration during exposure can be appropriately selected. In addition to exposure in the atmosphere, exposure may be performed in a low-oxygen atmosphere 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 atmosphere with an oxygen concentration of more than 21% by volume (e.g., 22% by volume, 30% by volume, or 50% by volume). The exposure illuminance can be appropriately set, and is usually 1000 W / m 2 ~100,000W / m 2 (e.g., 5000W / m 2 , 15000W / m 2 , or 35,000 W / m 2 The oxygen concentration and exposure illuminance may be appropriately combined. For example, an oxygen concentration of 10% by volume and an illuminance of 10,000 W / m 2, oxygen concentration 35% by volume, illuminance 20000W / m 2 etc.
[0212] Next, the unexposed portions of the composition layer after exposure are developed and removed to form a pattern. The unexposed portions of the composition layer can be developed and removed using a developer. As a result, the unexposed portions of the composition layer in the exposure step are dissolved into the developer, and only the photocured portions remain 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 residue removal, the process of shaking off the developer every 60 seconds and then supplying fresh developer may be repeated several times.
[0213] Examples of the developer include organic solvents and alkaline developers, and alkaline developers are preferably used. Regarding the developer and the washing (rinsing) method after development, the developer and washing method described in paragraph 0214 of WO 2022 / 085485 can be used.
[0214] After development and drying, it is preferable to perform additional exposure treatment or heating treatment (post-baking). The additional exposure treatment or post-baking is a post-development curing treatment to ensure complete curing.
