Description

Coloring composition, film, red pixel, color filter, solid-state imaging element, image display device and kit

The present invention relates to a coloring composition containing pigments. In addition, the present invention relates to a film, a red pixel, a color filter, a solid-state imaging device, and an image display device formed by using a colored composition. In addition, the present invention relates to kits.

In recent years, with the spread of digital cameras, mobile phones with cameras, etc., the demand for solid-state imaging devices such as charge-coupled device (CCD) image sensors has increased significantly. As a core device of a display or optical element, a color filter is used. The color filter usually has pixels of the three primary colors of red, green, and blue, and plays a role of decomposing the transmitted light into the three primary colors.

Colored pixels of each color of the color filter are manufactured using a coloring composition containing color materials such as pigments. In addition, in the coloring composition for forming a red pixel, a diketopyrrolopyrrole pigment or the like is used as the red pigment. For example, Patent Document 1 describes a technique for forming a red pixel using a coloring composition containing a red pigment such as a color index pigment red 272 as a diketopyrrolopyrrole pigment.

＜Evaluation＞ (Evaluation of impurities) The colored composition obtained above was filtered with DFA4201J006P (manufactured by NIHON PALL Corporation), and then the filtered composition was filtered with DFA4201NAEY (manufactured by NIHON PALL Corporation), and stored at a temperature of 7°C. After 1 month, 3 months, 6 months, 9 months, 12 months, 15 months, or 24 months from the beginning of storage, confirm whether there are impurities on the film formed on the silicon wafer according to the following method. In a class 1000 clean room, the colored composition is coated on an 8-inch (=20.32cm) silicon wafer by spin coating to make the film thickness after coating 0.45μm. After that, it was heated at 100°C for 2 minutes to produce a film. The obtained film was inspected using ComPLUS3, a wafer defect evaluation device manufactured by AMAT, to confirm the presence or absence of impurities with a size of 0.5 μm or more. In addition, in an 8-inch silicon wafer, the area from the outer periphery to the inner side of 5mm or more is used as the inspection range. -Evaluation criteria- 1: Impurities are generated on the film made with the colored composition that has been stored for 9 months 2: There are no impurities on the film made with the colored composition that has been stored for 9 months, but impurities have been generated on the film made with the colored composition that has been stored for 12 months 3: Impurities are not generated on the film made with the colored composition that has been stored for 12 months, but impurities are generated on the film made with the colored composition that has been stored for 15 months 4: No impurities are generated on the film made with the colored composition stored for 15 months, but impurities are generated on the film made with the colored composition stored for 24 months 5: No impurities are produced on the film made with the colored composition that has been stored for 24 months

(Evaluation of spectroscopic characteristics) Each coloring composition was coated on a glass substrate by a spin coating method, followed by a heating treatment (pre-baking) at 100°C for 120 seconds using a hot plate, followed by i-ray Exposure was performed at an exposure amount of 1000 mj/cm ² , and then heating was performed at 200° C. for 5 minutes to produce a film with a thickness of 0.4 μm. Using MCPD-3000 manufactured by Otsuka Electronics Co., Ltd., the light transmittance (transmittance) in the range of 400 to 700 nm was measured for the obtained film. When the average value of the transmittance at 470 to 570 nm was set to T1, the spectral characteristic as red was judged based on the following criteria. The lower the value of T1, the more excellent the spectral characteristics as red. 3: T1 is less than 20% 2: T1 is more than 20% and less than 30% 1: T1 is more than 30%

As shown in the above table, the colored composition of the example can form a film that can suppress the generation of impurities even after long-term storage. In addition, in the film obtained from the colored composition of the example, the average value of the transmittance at 470 to 570 nm was low, and the spectral characteristic as a red color was excellent.

(Example 1001) A green coloring composition was applied on a silicon wafer by a spin coating method so that the film thickness after film formation became 0.45 μm. Next, using a hot plate, it was heated at 100°C for 2 minutes. Next, using an i-ray stepper exposure device FPA-3000i5+ (manufactured by Canon Inc.), ^{exposure was performed at an exposure amount of 1000 mJ/cm 2} through a mask of a 0.7 μm square dot pattern. Next, 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 with a rotary shower, and further rinsed with pure water. Next, it was heated at 200° C. for 5 minutes using a hot plate, thereby patterning the green coloring composition to form green pixels. Similarly, the red coloring composition and the blue coloring composition are patterned by the same process to form red pixels and blue pixels in sequence, thereby forming a color filter with green pixels, red pixels, and blue pixels . In this color filter, green pixels are formed in a Bayer pattern, and red pixels and blue pixels are formed in an island-shaped pattern in the adjacent area. The obtained color filter is embedded in the solid-state imaging element according to a known method. The solid-state imaging element has better image recognition capabilities.
