Description

Coloring composition, film, filter, solid-state imaging element and image display device

The present invention relates to a coloring composition containing a coloring agent, and also to a film, a filter, a solid-state imaging element and an image display device using the coloring composition.

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

Each color pixel of the color filter is manufactured using a coloring composition containing a coloring agent.

On the other hand, Patent Document 1 discloses a technique for using a compound having the following structure as an emitter material for an organic electroluminescent device. In the formula, rings A, B, and C each independently represent a 5-membered or 6-membered carbon ring or a heterocyclic ring, ^X1 to ^X9 each independently represent C or N, M represents Pd or Pt, and ^RA , ^RB , ^RC , and ^RD each independently represent hydrogen or a substituent. [Chemical Formula 1]

[Patent Document 1] U.S. Patent Application Publication No. 2020/0161568

In recent years, there is a demand for further improvement in resolution performance in solid-state imaging devices. Therefore, filters used in solid-state imaging devices are required to have fewer defects in the film. This is because if there are more defects in the film, color unevenness or brightness unevenness will occur, which will easily reduce resolution performance.

Furthermore, regarding optical filters such as color filters, further improvement in light resistance and heat resistance is required.

Furthermore, although Patent Document 1 describes the use of the above-mentioned compound as an emitter material of an organic electroluminescent device, it does not describe the use of the above-mentioned compound in a light filter.

Therefore, an object of the present invention is to provide a coloring composition capable of forming a film having excellent light resistance and heat resistance and suppressed defects. Another object of the present invention is to provide a film, a filter, a solid-state imaging element, and an image display device formed using the coloring composition.

<Method for producing film> 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 to further include a step of forming a pattern (pixel). As a method for forming a pattern (pixel), photolithography and dry etching can be listed, and photolithography is preferred.

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

In the step of forming a coloring composition layer, the coloring composition of the present invention is used to form a coloring composition layer on a support. There is no particular limitation on the support, and it can be appropriately selected according to the purpose. For example, a glass substrate, a silicon substrate, etc. can be listed, and a silicon substrate is preferred. In addition, a charge coupled device (CCD), a complementary metal oxide semiconductor (CMOS), a transparent conductive film, etc. can also be formed on the silicon substrate. In addition, a black matrix is sometimes formed on the silicon substrate to isolate each pixel. In addition, on the silicon substrate, a base layer can also be provided to improve the adhesion with the upper layer, prevent the diffusion of substances, or flatten the surface of the substrate. The surface contact angle of the base layer is preferably 20 to 70° when measured with diiodomethane, and preferably 30 to 80° when measured with water.

As a method for applying the coloring composition, a known method can be used. For example, the application method described in paragraph 0207 of International Publication No. 2022/085485 can be used.

The coloring composition layer formed on the support can be dried (pre-baked). When the film is manufactured by a low-temperature process, pre-baking is not required. When pre-baking is performed, the pre-baking temperature is preferably below 150°C, more preferably below 120°C, and further preferably below 110°C. The lower limit can be set to, for example, above 50°C, and can also be set to above 80°C. The pre-baking time is preferably 10 to 300 seconds, more preferably 40 to 250 seconds, and further preferably 80 to 220 seconds. Pre-baking can be performed using a heating plate, an oven, etc.

Next, the coloring component layer is exposed in a pattern (exposure step). For example, a stepper or scanner exposure machine is used to expose the coloring component layer through a mask having a predetermined mask pattern, thereby exposing the layer in a pattern. This allows the exposed portion to be cured.

As radiation (light) that can be used for exposure, g-ray, i-ray, etc. can be listed. 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 ray (wavelength 248nm), ArF ray (wavelength 193nm), etc. can be listed, and KrF ray (wavelength 248nm) is preferred. In addition, a light source with a long wavelength of 300nm or more can also be used. As a light source, an electrodeless ultraviolet lamp system, ultraviolet and infrared mixed curing can be used.

Furthermore, during exposure, light may be irradiated continuously or in pulses (pulse exposure). Pulse exposure refers to an exposure method in which light is irradiated and paused repeatedly in a short period of time (e.g., less than milliseconds) to perform exposure.

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

Next, the unexposed portion of the coloring component layer is removed by development to form a pattern (pixel). The unexposed portion of the coloring component layer can be removed by development using a developer. Thereby, the unexposed portion of the coloring component layer in the exposure step is dissolved into the developer, and only the photohardened portion remains. For example, the temperature of the developer is preferably 20 to 30°C. The developing time is preferably 20 to 180 seconds. In addition, in order to improve the removability of residues, the step of discarding the developer every 60 seconds and then supplying a new developer can be repeated multiple times.

The developer may be an organic solvent, an alkaline developer, etc., and an alkaline developer is preferably used. As for the developer and the washing (rinsing) method after development, the developer or washing method described in paragraph 0214 of International Publication No. 2022/085485 can be used.

After development, it is preferred to perform additional exposure treatment or heating treatment (post-baking) after drying. Additional exposure treatment or post-baking is a hardening treatment after development for complete hardening. The heating temperature in post-baking is preferably 100 to 240°C, and more preferably 200 to 240°C. In order to achieve the above conditions, a heating mechanism such as a heating plate, a convection oven (hot air circulation dryer), a high-frequency heater, etc. can be used to post-bake the developed film continuously or intermittently. When performing additional exposure treatment, it is preferred that the light used for exposure has a wavelength of less than 400nm. In addition, the additional exposure treatment can be performed by the method described in Korean Patent Publication No. 10-2017-0122130.

The pattern formation by dry etching preferably includes the following steps: forming a coloring composition layer on a support using the coloring composition of the present invention, and curing the coloring composition layer as a whole to form a hardened layer; forming a photoresist layer on the hardened layer; exposing the photoresist layer in a pattern and then developing it to form an anti-etchant pattern; and using the anti-etchant pattern as a mask and dry etching the hardened layer using an etching gas. When forming the photoresist layer, it is preferred to further perform a pre-baking treatment. In particular, as a process for forming the photoresist layer, it is desirable to perform a heat treatment after exposure and a heat treatment after development (post-baking treatment). For details on forming a pattern by dry etching, reference can be made to paragraphs 0010 to 0067 of Japanese Patent Application Laid-Open No. 2013-064993, and the details are incorporated into this specification.

When the protective layer is formed by chemical vapor deposition, a known chemical vapor deposition method (thermal chemical vapor deposition, plasma chemical vapor deposition, photochemical vapor deposition) can be used as the chemical vapor deposition method.

If necessary, the protective layer may contain additives such as organic/inorganic particles, absorbers of light of a specific wavelength (e.g., ultraviolet rays, near infrared rays, etc.), refractive index adjusters, antioxidants, adhesives, and surfactants.

＜Evaluation of defects＞ Each coloring composition was applied to an 8-inch (20.32 cm) silicon wafer using a coating and development device (CLEAN TRACK ACT-8, manufactured by Tokyo Electron Limited), and then preheated (pre-baked) at 100°C for 120 seconds. Then, post-heated (post-baked) was performed at 200°C for 30 minutes to produce a film with a thickness of 0.8 μm. The silicon wafer on which the film was formed was inspected using a defect inspection device (ComPLUS3, manufactured by Applied Materials, Inc.) to detect defective parts (agglomerates), and the number of defects larger than 1 μm per 2462 ^cm2 was extracted. A: The number of defects is less than 20B: The number of defects is more than 20 and less than 50C: The number of defects is more than 50 and less than 100D: The number of defects is more than 100

<Evaluation of heat resistance> The obtained film was heated at 260°C for 300 seconds using a heating plate. The transmittance of the film to light of wavelength 400nm to 1200nm before and after heating was measured using a spectrophotometer U-4100 (manufactured by Hitachi High-Tech Corporation.). In the wavelength range of 400nm to 1200nm, the change in transmittance at the wavelength where the change in transmittance before and after heating was the largest was calculated by the following formula, and the heat resistance was evaluated according to the following criteria. Change in transmittance = |(transmittance of the film after heating - transmittance of the film before heating)| A: Change in transmittance is less than 3% B: Change in transmittance is 3% or more and less than 5% C: Change in transmittance is 5% or more and less than 7% D: Change in transmittance is 7% or more

<Evaluation of light resistance> The obtained film was placed in a fading tester equipped with a super xenon lamp and irradiated with 100,000 lux of light for 50 hours without using a UV cut filter. Then, the transmission spectrum of the film after light irradiation was measured using a spectrophotometer U-4100 (manufactured by Hitachi High-Tech Corporation.). In the wavelength range of 400nm to 1200nm, the change in transmittance at the wavelength where the change in transmittance before and after light irradiation was the largest was calculated by the following formula, and the light resistance was evaluated according to the following criteria. Transmittance change = |(transmittance of the film after light irradiation - transmittance of the film before light irradiation)| A: Transmittance change is less than 3% B: Transmittance change is 3% or more and less than 5% C: Transmittance change is 5% or more and less than 7% D: Transmittance change is 7% or more
