Description

硬化性組成物、硬化膜、圖案的形成方法、濾光器及光學感測器Curable composition, cured film, pattern formation method, optical filter and optical sensor

本發明關於一種硬化性組成物、硬化膜、圖案的形成方法、濾光器及光學感測器。The invention relates to a curable composition, a cured film, a pattern forming method, an optical filter and an optical sensor.

以往，在電荷耦合元件（CCD）圖像感測器等固體攝像元件中，已經嘗試使用濾色器進行圖像的著色等。例如，專利文獻1中記載有一種固體攝像元件，其具備：半導體基板；濾色器陣列，具有2色以上的濾色器層及至少隔著不同顏色的濾色器層間分離之分離壁；及集光機構，配置於半導體基板與濾色器陣列之間。In the past, in solid-state imaging devices such as charge-coupled device (CCD) image sensors, attempts have been made to use color filters to color images. For example, Patent Document 1 describes a solid-state imaging element that includes: a semiconductor substrate; a color filter array including two or more color filter layers and at least a separation wall that separates the color filter layers of different colors; and The light collecting mechanism is arranged between the semiconductor substrate and the color filter array.

又，近年來，已經對感測近紅外線之光學感測器進行了研究。近紅外線的波長與可見光線相比，波長長，因此難以散射，亦能夠用於距離測量、三維測量等。又，由於近紅外線對於人、動物等是看不見的，因此即使在夜間使用近紅外線照射被攝體亦不會被被攝體發現，在無需刺激對象亦能夠作為拍攝夜間野生動物之用途、防犯用途使用於拍攝。這樣，感測近紅外線之光學感測器能夠用於各種用途。在該種光學感測器中，使用在近紅外線透過濾波器等的近紅外線區域具有透過帶之濾波器等（例如，參閱專利文獻2、專利文獻3）。Furthermore, in recent years, optical sensors that sense near-infrared rays have been studied. The wavelength of near-infrared rays is longer than that of visible light, so it is difficult to scatter. It can also be used for distance measurement, three-dimensional measurement, etc. In addition, since near-infrared rays are invisible to people, animals, etc., even if you use near-infrared rays to illuminate a subject at night, you will not be noticed by the subject. It can also be used to photograph wild animals at night and to prevent crime even if there is no need to stimulate the subject. Purpose: Used for photography. In this way, optical sensors that sense near-infrared rays can be used for various purposes. In this type of optical sensor, a near-infrared transmission filter or the like having a transmission band in the near-infrared region is used (for example, see Patent Document 2 and Patent Document 3).

通常，如上所述的濾色器及近紅外線透過濾波器藉由如下方法來製造：使用包含色材、聚合性化合物及光聚合起始劑之硬化性組成物形成膜，並藉由加熱等使該膜硬化。例如，專利文獻4中記載有，使用硬化性組成物製造濾色器，該硬化性組成物使用包含氟原子之肟酯系光聚合起始劑作為光聚合起始劑。 [先前技術文獻] [專利文獻]Generally, the above-mentioned color filter and near-infrared transmission filter are produced by forming a film using a curable composition containing a color material, a polymerizable compound, and a photopolymerization initiator, and heating or the like. The film hardens. For example, Patent Document 4 describes manufacturing a color filter using a curable composition using an oxime ester-based photopolymerization initiator containing a fluorine atom as a photopolymerization initiator. [Prior technical literature] [Patent Document]

[專利文獻1]美國專利第9496164號說明書 [專利文獻2]日本專利第6034796號公報 [專利文獻3]日本特開2017-050322號公報 [專利文獻4]國際公開第2016/158114號[Patent Document 1] U.S. Patent No. 9496164 Specification [Patent Document 2] Japanese Patent No. 6034796 [Patent Document 3] Japanese Patent Application Publication No. 2017-050322 [Patent Document 4] International Publication No. 2016/158114

此番，發現了當使用近紅外線透過濾波器用組成物形成硬化膜時，波長365nm的光由於其分光特性而難以透過，因此在曝光時，雖然膜的表層部硬化，但是深層部難以硬化。當色材的濃度高時，組成物的深層部的硬化變得更加困難。因此，為了使上述硬化性組成物充分硬化並提高與基底的密接性，可考慮進行200℃以上的加熱處理。 然而，近年來，研究了在固體攝像元件中，從高解析度、高靈敏度、節省電力及小型化等的觀點考慮，代替Si系材料使用有機材料、量子點及InGaAs（砷化銦鎵）等非Si系材料進行光電轉換。如上所述的非Si系材料與Si系材料相比對熱較弱，因此期望將使硬化性組成物硬化時的加熱溫度設為小於200℃。This time, it was found that when a near-infrared ray-transmitting filter composition is used to form a cured film, light with a wavelength of 365 nm is difficult to transmit due to its spectral characteristics. Therefore, when exposed, the surface layer of the film is cured, but the deep layer is difficult to be cured. When the concentration of the color material is high, hardening of the deep parts of the composition becomes more difficult. Therefore, in order to fully harden the above-mentioned curable composition and improve the adhesiveness with the substrate, it may be considered to perform a heat treatment at 200° C. or above. However, in recent years, studies have been conducted on using organic materials, quantum dots, InGaAs (indium gallium arsenide), etc. instead of Si-based materials in solid-state imaging elements from the viewpoints of high resolution, high sensitivity, power saving, and miniaturization. Non-Si materials perform photoelectric conversion. Since the non-Si-based materials described above are less resistant to heat than Si-based materials, it is desirable to set the heating temperature when hardening the curable composition to less than 200°C.

因此，考慮到近年來的技術趨向，期望即使在使用近紅外線透過濾波器用組成物形成硬化膜時，在低溫下亦能夠充分硬化至膜的深層部而可獲得密接性優異的膜。Therefore, in consideration of recent technological trends, it is desired that even when a cured film is formed using a composition for a near-infrared ray transmitting filter, the film can be sufficiently cured to a deep part of the film at low temperature to obtain a film with excellent adhesion.

本發明係鑑於上述要求而完成者，其目的在於提供一種能夠在低溫下形成密接性優異之硬化膜之硬化性組成物。The present invention was made in view of the above requirements, and an object thereof is to provide a curable composition capable of forming a cured film with excellent adhesion at low temperatures.

又，本發明的目的在於，提供一種使上述硬化性組成物硬化而獲得之硬化膜、使用上述硬化性組成物之圖案的形成方法。此外，本發明的目的在於，提供一種具有上述硬化膜之濾光器及光學感測器。Furthermore, an object of the present invention is to provide a cured film obtained by curing the above-mentioned curable composition and a method of forming a pattern using the above-mentioned curable composition.

＜硬化性組成物＞ 本發明的硬化性組成物含有色材、聚合性化合物、光聚合起始劑。並且，在本發明的硬化性組成物中，色材的含量相對於組成物的總固體成分為30質量%以上。此外，光聚合起始劑包含甲醇中的波長365nm的吸光係數為1.0×103 mL/gcm以上的光聚合起始劑A1、及甲醇中的波長365nm的吸光係數為1.0×102 mL/gcm以下且波長254nm的吸光係數為1.0×103 mL/gcm以上的光聚合起始劑A2。又，組成物的波長400～600nm的範圍內的吸光度的最小值A與波長1000～1300nm的範圍內的吸光度的最大值B之比A/B為4.5以上，亦即，本發明的硬化性組成物具有容易吸收可見光並且容易使近紅外線透過之分光特性。因此，例如用於製造近紅外線透過濾波器。另外，在本說明書中，“近紅外”係指700～2500nm的波長範圍周邊。在本發明的硬化性組成物中，由於如上所述的分光特性的結果、可見光區域的吸收特性的基礎的影響等，對波長365nm的光的透過率亦相對變低。<Curable composition> The curable composition of the present invention contains a color material, a polymerizable compound, and a photopolymerization initiator. Furthermore, in the curable composition of the present invention, the content of the color material is 30% by mass or more based on the total solid content of the composition. In addition, the photopolymerization initiator includes photopolymerization initiator A1 whose absorbance coefficient at a wavelength of 365 nm in methanol is 1.0×10 3 mL/gcm or more, and photopolymerization initiator A1 whose absorbance coefficient at a wavelength of 365 nm in methanol is 1.0×10 2 mL/gcm The photopolymerization initiator A2 is below and has an absorption coefficient of 1.0×10 3 mL/gcm or more at a wavelength of 254 nm. Furthermore, the ratio A/B of the minimum absorbance value A in the wavelength range of 400 to 600 nm and the maximum absorbance value B in the wavelength range of 1000 to 1300 nm is 4.5 or more, that is, the curable composition of the present invention is Objects have spectroscopic properties that easily absorb visible light and easily transmit near-infrared rays. Therefore, it is used, for example, to manufacture near-infrared ray-transmitting filters. In addition, in this specification, "near infrared" refers to the vicinity of the wavelength range of 700 to 2500 nm. In the curable composition of the present invention, the transmittance to light with a wavelength of 365 nm is also relatively low due to the above-mentioned spectral characteristics, the basic influence of the absorption characteristics in the visible light region, and the like.

藉由使用本發明的硬化性組成物，能夠在低溫下形成密接性優異之硬化膜。認為其作用為如下。By using the curable composition of the present invention, a cured film excellent in adhesion can be formed at low temperature. Its function is considered to be as follows.

以往，硬化性組成物的曝光中，主要使用波長365nm的紫外線（所謂的i射線）。此番，當使用該種紫外線進行曝光時，發現了如下問題：在本發明的硬化性組成物中，大部分紫外線被膜的表層部吸收，足夠的光量的紫外線有時不會到達深層部。尤其，近年來，色材的濃度有增加的趨勢，如本發明在色材的含量相對於組成物的總固體成分成為30質量%以上之高濃度之情況下，明顯表現出上述問題。Conventionally, ultraviolet rays with a wavelength of 365 nm (so-called i-rays) have been mainly used for exposure of curable compositions. This time, when this kind of ultraviolet light was used for exposure, the following problem was discovered: in the curable composition of the present invention, most of the ultraviolet rays are absorbed by the surface layer of the film, and a sufficient amount of ultraviolet rays sometimes does not reach the deep layers. In particular, in recent years, the concentration of coloring materials has tended to increase. In the present invention, when the content of coloring materials reaches a high concentration of 30% by mass or more relative to the total solid content of the composition, the above-mentioned problems are clearly manifested.

因此，在本發明中，硬化性組成物包含光聚合起始劑A1及光聚合起始劑A2，因此在使用具有大於350nm且380nm以下的波長（例如365nm）之光進行之曝光（第1曝光）及使用具有254～350nm的波長（例如254nm）之光進行之曝光（第2曝光）這2個階段實施曝光，並設計為在小於200℃的低溫下獲得充分的硬化。在本說明書中，關於除了可見區域以外的電磁波，亦為了方便而使用“光”這一術語，對於除了可見區域以外的電磁波，“光”的含義與“電磁波”的含義相同。另外，當不要求將本發明的硬化性組成物應用於不使用上述非Si系材料之固體攝像元件等、在小於200℃的低溫下硬化時，不實施上述第2曝光，亦能夠藉由加熱處理充分地硬化組成物。亦即，本發明的硬化性組成物除了用於曝光為2個階段之方法以外，還能夠用於曝光為1個階段之方法。Therefore, in the present invention, since the curable composition contains the photopolymerization initiator A1 and the photopolymerization initiator A2, the exposure (first exposure) using light having a wavelength of more than 350 nm and less than 380 nm (for example, 365 nm) ) and exposure using light with a wavelength of 254 to 350 nm (for example, 254 nm) (second exposure), the exposure is performed in two stages, and is designed to obtain sufficient hardening at a low temperature of less than 200°C. In this specification, the term "light" is also used for convenience regarding electromagnetic waves other than the visible region, and "light" has the same meaning as "electromagnetic wave" regarding electromagnetic waves other than the visible region. In addition, when it is not required to apply the curable composition of the present invention to a solid-state imaging element that does not use the above-mentioned non-Si-based material, and it is cured at a low temperature of less than 200°C, the above-mentioned second exposure can also be performed by heating. Process to harden the composition sufficiently. That is, the curable composition of the present invention can be used in a method in which exposure is in one step, in addition to a method in which exposure is performed in two steps.

具體而言，如下所述。通常，在曝光中，吸收光之光聚合起始劑產生活性物種，藉由該活性物種的活性作用促進聚合性化合物的聚合。然而，如本發明的硬化性組成物，上述A/B為4.5以上之組成物中，例如與濾色器用組成物等相比，除了光聚合起始劑以外的成分（尤其色材）具有容易吸收可見光之性質，隨此，接近可見光域365nm的波長的光亦容易被除光聚合起始劑以外的成分吸收。在該種組成物中，即使使用365nm的波長的光進行曝光，光被膜的表層部吸收，並且光難以到達膜的深層部，因此深層部的硬化不良成為問題。另一方面，在該曝光中，若欲充分硬化至深層部而增加曝光能量，則存在在表層部必要以上地產生之活性物種在膜中擴散，圖案的表層部變得比目標尺寸更厚的另一問題。Specifically, it is as follows. Generally, during exposure, a photopolymerization initiator that absorbs light generates active species, and the polymerization of the polymerizable compound is promoted by the active effect of the active species. However, in the curable composition of the present invention, in a composition in which the above-mentioned A/B is 4.5 or more, for example, compared with a composition for a color filter, etc., components other than the photopolymerization initiator (especially color materials) are more likely to have Due to its ability to absorb visible light, light with a wavelength close to 365 nm in the visible light range is easily absorbed by components other than the photopolymerization initiator. In this composition, even if light with a wavelength of 365 nm is used for exposure, the light is absorbed by the surface layer of the film, and the light hardly reaches the deep portion of the film, so poor hardening of the deep portion becomes a problem. On the other hand, if the exposure energy is increased in order to fully harden the deep layer during the exposure, the active species generated in the surface layer will diffuse in the film more than necessary, and the surface layer of the pattern may become thicker than the target size. Another question.

因此，在本發明中，使用365nm的波長的光進行之曝光（第1曝光）作為將能夠承受顯影之程度的強度賦予到硬化性組成物之製程，在第1曝光及顯影後，實施利用光聚合起始劑A2之第2曝光。在第2曝光中，圖案已經被切割，由於過量產生之活性物種的擴散而對圖案尺寸的影響小，因此能夠提高曝光能量。因此，能夠使足夠的光到達光聚合起始劑A2直至硬化性組成物的深層部，並且能夠充分地促進深層部的硬化。又，在本發明中，光聚合起始劑A2的波長365nm的吸光係數相對較低，能夠抑制第1曝光中的光聚合起始劑A2的消耗，因此在第2曝光中，有效地促進聚合性化合物的聚合。尤其，在色材的濃度高，進而膜厚有變厚的趨勢之近紅外線透過濾波器中，膜的深層部的硬化不良是個大問題，本發明對在該種用途中所使用之組成物尤其有用。Therefore, in the present invention, exposure using light with a wavelength of 365 nm (first exposure) is used as a process to impart strength to the curable composition that can withstand development. After the first exposure and development, the use of light is performed. Second exposure of polymerization initiator A2. In the second exposure, the pattern has already been cut, and due to the diffusion of excessively generated active species, the effect on the pattern size is small, so the exposure energy can be increased. Therefore, sufficient light can reach the photopolymerization initiator A2 to the deep part of the curable composition, and hardening of the deep part can be fully promoted. Furthermore, in the present invention, the light absorption coefficient of the photopolymerization initiator A2 at a wavelength of 365 nm is relatively low, and the consumption of the photopolymerization initiator A2 in the first exposure can be suppressed. Therefore, the polymerization is effectively promoted in the second exposure. Polymerization of sexual compounds. In particular, in near-infrared transmission filters where the concentration of color materials is high and the film thickness tends to become thicker, poor hardening of the deep portion of the film is a big problem. The present invention is particularly useful for compositions used in such applications. it works.

藉由實施該種第2曝光，即使在第1曝光中硬化性組成物的深層部的硬化不充分，亦能夠藉由在第2曝光中組成物的深層部充分硬化，且經膜深層部的機械強度提高來提高與基底的密接性。尤其，在用於製造遮擋波長400～600nm的光，並透過波長750nm以下的光之近紅外線透過濾波器、遮擋波長400～750nm的光，並透過波長850nm以下的光之近紅外線透過濾波器之硬化性組成物的情況下，由於其分光特性，波長365nm的紫外光尤其難以到達至膜的深層部，因此上述2段階曝光帶來之好處超出了能夠從以往技術預測之範圍。By performing this second exposure, even if the deep part of the curable composition is not sufficiently hardened in the first exposure, the deep part of the composition can be sufficiently hardened in the second exposure, and the deep part of the membrane can be cured. Improved mechanical strength improves adhesion to the substrate. In particular, it is used to manufacture a near-infrared transmission filter that blocks light with a wavelength of 400 to 600 nm and transmits light with a wavelength of 750 nm or less, and a near-infrared transmission filter that blocks light with a wavelength of 400 to 750 nm and transmits light with a wavelength of 850 nm or less. In the case of curable compositions, due to its spectroscopic characteristics, ultraviolet light with a wavelength of 365 nm is particularly difficult to reach the deep parts of the film. Therefore, the benefits of the above two-stage exposure are beyond the range that can be predicted from the previous technology.

上述A/B為5以上為較佳，7.5以上為更佳，15以上為進一步較佳，30以上為特佳。又，上述A/B為500以下為較佳，400以下為更佳，300以下為進一步較佳。 某一波長λ下的吸光度Aλ藉由以下式（1）來定義。 Aλ=-log（Tλ/100）   ・・・（1） Aλ為波長λ下的吸光度，Tλ為波長λ下的透過率（%）。The above-mentioned A/B is preferably 5 or more, more preferably 7.5 or more, further preferably 15 or more, and 30 or more is particularly good. Moreover, the above-mentioned A/B is preferably 500 or less, more preferably 400 or less, and still more preferably 300 or less. The absorbance Aλ at a certain wavelength λ is defined by the following formula (1). Aλ=-log（Tλ/100）・・・(1) Aλ is the absorbance at wavelength λ, and Tλ is the transmittance (%) at wavelength λ.

在本發明中，吸光度的值可以為以溶液的狀態測量而得之值，亦可以為使用硬化性組成物製膜而得之膜中的值。當以膜的狀態測量吸光度時，在玻璃基板上藉由旋塗等方法以乾燥後的膜的厚度成為規定的厚度之方式塗佈硬化性組成物，並使用利用加熱板在100℃下乾燥120秒鐘後製備而成之膜進行測量為較佳。能夠使用觸針式表面形狀測量儀（ULVAC, Inc.製 DEKTAK150）對具有膜之基板測量膜的厚度。In the present invention, the absorbance value may be a value measured in the state of a solution, or may be a value in a film formed using a curable composition. When measuring absorbance in the state of a film, apply a curable composition on a glass substrate by spin coating or other methods so that the thickness of the dried film becomes a predetermined thickness, and dry using a hot plate at 100°C for 120 It is better to measure the film prepared after 2 seconds. The thickness of the film can be measured on the substrate with the film using a stylus type surface profile measuring instrument (DEKTAK150 manufactured by ULVAC, Inc.).

又，吸光度能夠使用以往公知的分光光度計來測量。在將波長400～600nm的範圍內的吸光度的最小值A調整為0.1～3.0之條件下，測量波長1000～1300nm的範圍內的吸光度的最大值B為較佳。藉由在該種條件下測量吸光度，能夠進一步減小測量誤差。作為將波長400～600nm的範圍內的吸光度的最小值A調成為0.1～3.0之方法，並無特別限定。例如，當在溶液的狀態下測量吸光度時，可列舉調整試樣池的光路長度之方法。又，當在膜的狀態下測量吸光度時，可列舉調整膜厚之方法等。吸光度例如能夠使用紫外可見近紅外分光光度計來測量。作為該種裝置，例如能夠使用U-4100（Hitachi High-Technologies Corporation製）。In addition, the absorbance can be measured using a conventionally known spectrophotometer. It is preferable to measure the maximum value B of the absorbance in the range of 1000 to 1300 nm while adjusting the minimum value A of the absorbance in the range of 400 to 600 nm to 0.1 to 3.0. By measuring the absorbance under such conditions, the measurement error can be further reduced. There is no particular limitation on the method of adjusting the minimum value A of the absorbance in the wavelength range of 400 to 600 nm to 0.1 to 3.0. For example, when measuring absorbance in the state of a solution, one method is to adjust the optical path length of the sample cell. In addition, when the absorbance is measured in a film state, a method of adjusting the film thickness may be used. The absorbance can be measured, for example, using a UV-visible-near-infrared spectrophotometer. As such a device, for example, U-4100 (manufactured by Hitachi High-Technologies Corporation) can be used.

The lower limit is preferably 3 mmol/g or more, more preferably 4 mmol/g or more, and still more preferably 5 mmol/g or more.

形成於支撐體上之硬化性組成物層可以進行乾燥（預烘烤）。進行預烘烤之情況下，預烘烤溫度為80℃以下為較佳，70℃以下為更佳，60℃以下為進一步較佳，50℃以下為特佳。下限例如能夠設為40℃以上。預烘烤時間為10～3600秒為較佳。預烘烤能夠由加熱板、烘箱等進行。The curable composition layer formed on the support may be dried (prebaked). When prebaking is performed, the prebaking temperature is preferably 80°C or lower, more preferably 70°C or lower, further preferably 60°C or lower, and particularly preferably 50°C or lower. The lower limit can be set to 40°C or higher, for example. The optimal pre-baking time is 10 to 3600 seconds. Prebaking can be performed by a heating plate, oven, etc.

＜＜第1曝光製程＞＞ 在第1曝光製程中，對硬化性組成物層照射大於350nm且380nm以下的波長的光並以圖案狀進行曝光。例如，使用步進機等曝光裝置經由具有規定的遮罩圖案之遮罩，對硬化性組成物層進行曝光，藉此能夠以圖案狀進行曝光。藉此，能夠硬化硬化性組成物層的曝光部分。作為能夠在曝光時使用之光，為大於350nm且380nm以下的波長的光，波長355～370nm的光為較佳，i射線（365nm）為更佳。又，如KR1020170122130A中所記載，可以一邊切割比i射線短的波長的光一邊進行該曝光處理。＜＜The first exposure process＞＞ In the first exposure process, the curable composition layer is irradiated with light having a wavelength of more than 350 nm and less than 380 nm and exposed in a pattern. For example, exposure in a pattern can be performed by exposing the curable composition layer through a mask having a predetermined mask pattern using an exposure device such as a stepper. Thereby, the exposed portion of the curable composition layer can be hardened. Light that can be used during exposure is light with a wavelength greater than 350 nm and less than 380 nm. Light with a wavelength of 355 to 370 nm is preferred, and i-ray (365 nm) is more preferred. Furthermore, as described in KR1020170122130A, this exposure process can be performed while cutting light with a wavelength shorter than i-rays.

作為照射量（曝光量），例如為30～1500mJ/cm2 為較佳，50～1000mJ/cm2 為更佳。關於曝光時之氧濃度，能夠進行適當選擇，除了在大氣下進行以外，亦可以例如在氧濃度為19體積%以下的低氧環境下（例如15體積%、5體積%、實質上無氧）進行曝光，亦可以在氧濃度大於21體積%之高氧環境下（例如22體積%、30體積%、50體積%）進行曝光。又，曝光照度能夠適當設定，通常能夠從1000W/m2 ～100000W/m2 （例如，5000W/m2 、15000W/m2 、35000W/m2 ）的範圍進行選擇。氧濃度與曝光照度可以組合適當條件，例如能夠在氧濃度10體積%下設為照度10000W/m2 ，在氧濃度35體積%下設為照度20000W/m2 等。As the irradiation amount (exposure amount), for example, 30 to 1500 mJ/cm 2 is preferred, and 50 to 1000 mJ/cm 2 is more preferred. The oxygen concentration during exposure can be appropriately selected. In addition to performing it in the atmosphere, it can also be performed in a low-oxygen environment with an oxygen concentration of 19 volume % or less (for example, 15 volume %, 5 volume %, substantially no oxygen). Exposure can also be carried out in a high oxygen environment with an oxygen concentration greater than 21 volume % (for example, 22 volume %, 30 volume %, 50 volume %). In addition, the exposure illuminance can be appropriately set, and can usually be selected from the range of 1000W/m 2 to 100000W/m 2 (for example, 5000W/m 2 , 15000W/m 2 , 35000W/m 2 ). The oxygen concentration and exposure illuminance can be combined with appropriate conditions. For example, the illuminance can be set to 10000W/m 2 at an oxygen concentration of 10% by volume, and the illuminance can be set to 20000W/m 2 at an oxygen concentration of 35% by volume.

在第1曝光製程中，曝光後的硬化性組成物層中的聚合性化合物的反應率為大於30%且小於80%為較佳。藉由設為該等反應率，能夠將聚合性化合物設為適當地進行硬化之狀態。在趨於色材的濃度高且光難以透過之近紅外線透過濾波器用的組成物中，使深層部硬化成能夠承受顯影之程度，因此與濾色器用組成物的情況相比，上述反應率設定為高為較佳。此外，在本發明中，上述反應率為40～75%為更佳，50～70%為進一步較佳。在此，聚合性化合物的反應率係指，在第1曝光製程前，聚合性化合物所具有之聚合性基中、已反應之聚合性基的比例。聚合性化合物的反應率藉由利用紅外吸收光譜法分析810cm-1 附近的峰面積而能夠作為膜的厚度方向的平均值來求出。In the first exposure process, the reaction rate of the polymerizable compound in the curable composition layer after exposure is preferably greater than 30% and less than 80%. By setting these reaction rates, the polymerizable compound can be brought into a state where it is appropriately cured. In a composition for a near-infrared transmission filter that tends to have a high concentration of color material and is difficult to transmit light, the deep portion is hardened to a level that can withstand development. Therefore, compared with the case of a composition for a color filter, the above reaction rate is set Higher is better. In addition, in the present invention, the above-mentioned reaction rate is more preferably 40 to 75%, and further more preferably 50 to 70%. Here, the reaction rate of the polymerizable compound refers to the ratio of the polymerizable groups that have reacted among the polymerizable groups the polymerizable compound has before the first exposure process. The reaction rate of the polymerizable compound can be determined as an average value in the thickness direction of the film by analyzing the peak area near 810 cm -1 using infrared absorption spectroscopy.

＜＜顯影製程＞＞ 在顯影製程中，將硬化性組成物層的未曝光部顯影去除而形成圖案（像素）。硬化性組成物層的未曝光部的顯影去除能夠使用顯影液來進行。藉此，曝光步驟中之未曝光部的硬化性組成物層溶出於顯影液，僅殘留光硬化之部分。作為顯影液，可列舉有機溶劑、鹼顯影液等，鹼顯影液為較佳。顯影液的溫度例如為20～30℃為較佳。顯影時間為20～180秒為較佳。又，為了提高殘渣去除性，可反覆進行數次如下步驟：每隔60秒甩去顯影液，進一步重新供給顯影液。＜＜Development process＞＞ In the development process, the unexposed portions of the curable composition layer are developed and removed to form patterns (pixels). The unexposed portion of the curable composition layer can be removed by development using a developer. Thereby, the curable composition layer in the unexposed portion in the exposure step is dissolved in the developer, and only the photohardened portion remains. Examples of the developer include organic solvents, alkali developers, and the like, with alkali developers being preferred. The temperature of the developer is preferably 20 to 30°C, for example. The development time is preferably 20 to 180 seconds. In addition, in order to improve the residue removability, the following steps can be repeated several times: shaking off the developer every 60 seconds and further supplying the developer again.

鹼性顯影液係用純水稀釋鹼劑而得之鹼性水溶液為較佳。作為鹼劑，例如可列舉胺、乙胺、二乙胺、二甲基乙醇胺、二甘醇胺、二乙醇胺、羥基胺、乙二胺、四甲基氫氧化銨、四乙基氫氧化銨、四丙基氫氧化銨、四丁基氫氧化銨、乙基三甲基氫氧化銨、苄基三甲基氫氧化銨、二甲基雙（2-羥基乙基）氫氧化銨、膽鹼、吡咯、哌啶、1,8-二氮雜雙環[5.4.0]-7-十一碳烯等有機鹼性化合物或氫氧化鈉、氫氧化鉀、碳酸鈉、碳酸氫鈉、矽酸鈉、偏矽酸鈉等無機鹼性化合物。關於鹼劑，分子量大的化合物在環境面及安全面方面較佳。鹼性水溶液的鹼劑的濃度為0.001～10質量%為較佳，0.01～1質量%為更佳。又，顯影液可進一步包含界面活性劑。作為界面活性劑，可列舉上述界面活性劑，非離子系界面活性劑為較佳。從運輸和保管方便等觀點考慮，顯影液暫且製成為濃縮液，亦可稀釋成使用時所需的濃度。對於稀釋倍率並無特別限定，但例如能夠設定在1.5～100倍的範圍。The alkaline developer is preferably an alkaline aqueous solution obtained by diluting an alkali agent with pure water. Examples of the alkaline agent include amine, ethylamine, diethylamine, dimethylethanolamine, diglycolamine, diethanolamine, hydroxylamine, ethylenediamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, Tetrapropylammonium hydroxide, tetrabutylammonium hydroxide, ethyltrimethylammonium hydroxide, benzyltrimethylammonium hydroxide, dimethylbis(2-hydroxyethyl)ammonium hydroxide, choline, Pyrrole, piperidine, 1,8-diazabicyclo[5.4.0]-7-undecene and other organic basic compounds or sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium silicate, Inorganic alkaline compounds such as sodium metasilicate. Regarding alkaline agents, compounds with large molecular weights are better in terms of environmental and safety aspects. The concentration of the alkali agent in the alkaline aqueous solution is preferably 0.001 to 10% by mass, and more preferably 0.01 to 1% by mass. Moreover, the developer may further contain a surfactant. Examples of the surfactant include the above-mentioned surfactants, and nonionic surfactants are preferred. From the viewpoint of transportation and storage convenience, the developer is temporarily made into a concentrated solution, which can also be diluted to the concentration required for use. The dilution ratio is not particularly limited, but can be set in the range of 1.5 to 100 times, for example.

又，顯影後利用純水進行清洗（沖洗）亦為較佳。又，沖洗藉由使形成有顯影後的硬化性組成物層之支撐體旋轉的同時向顯影後的硬化性組成物層供給沖洗液來進行為較佳。又，藉由使吐出沖洗液之噴嘴從支撐體的中心部向支撐體的周緣部移動來進行亦為較佳。此時，在從噴嘴的支撐體中心部向周緣部移動時，可以在逐漸降低噴嘴的移動速度的同時使其移動。藉由以該種方式進行沖洗，能夠抑制沖洗的面內偏差。又，藉由使噴嘴從支撐體中心部向周緣部移動的同時逐漸降低支撐體的轉速亦可獲得相同的效果。In addition, it is also preferable to use pure water for cleaning (rinsing) after development. Furthermore, rinsing is preferably performed by supplying a rinsing liquid to the developed curable composition layer while rotating the support on which the developed curable composition layer is formed. Furthermore, it is also preferable to move the nozzle that discharges the rinse liquid from the center of the support body to the peripheral edge of the support body. At this time, when moving from the center part of the support body of the nozzle to the peripheral edge part, the moving speed of the nozzle may be gradually reduced while moving it. By performing flushing in this manner, in-plane deviation of flushing can be suppressed. In addition, the same effect can be obtained by gradually reducing the rotation speed of the support body while moving the nozzle from the center part of the support body to the peripheral part.

＜＜第2曝光製程＞＞ 在第2曝光製程中，照射波長254～350nm的光並對硬化性組成物層進行曝光。照射之光包含波長300nm以下的光為較佳，包含波長254nm的光為更佳。在第2曝光製程中，例如能夠使用紫外線光阻劑硬化裝置來進行。亦可以從紫外線光阻劑硬化裝置與例如波長254～350nm的光一同照射除此以外的光（例如i射線）。在上述顯影前的曝光中所使用之光的波長與在顯影後的曝光（後曝光）中所使用之光的波長之差為200nm以下為較佳，100～150nm為更佳。＜＜Second Exposure Process＞＞ In the second exposure process, light with a wavelength of 254 to 350 nm is irradiated to expose the curable composition layer. The irradiated light preferably contains light with a wavelength of 300 nm or less, and more preferably contains light with a wavelength of 254 nm. In the second exposure process, for example, an ultraviolet photoresist curing device can be used. You may also irradiate other light (for example, i-ray) together with the light of wavelength 254-350 nm from an ultraviolet photoresist hardening apparatus, for example. The difference between the wavelength of the light used in the exposure before development and the wavelength of the light used in the exposure after development (post-exposure) is preferably 200 nm or less, and more preferably 100 to 150 nm.

照射量（曝光量）為30～4000mJ/cm2 為較佳，50～3500mJ/cm2 為更佳。關於曝光時的氧濃度，能夠與第1曝光製程時的條件同樣地適當選擇。The irradiation amount (exposure amount) is preferably 30 to 4000 mJ/cm 2 , and more preferably 50 to 3500 mJ/cm 2 . The oxygen concentration during exposure can be appropriately selected in the same manner as the conditions during the first exposure process.

在第2曝光製程中，曝光後的硬化性組成物層中的聚合性化合物的反應率為60%以上為較佳。上限能夠設為100%以下，亦能夠設為90%以下。藉由設為該等反應率，能夠更牢固地設為曝光後的硬化性組成物層的硬化狀態。In the second exposure process, the reaction rate of the polymerizable compound in the curable composition layer after exposure is preferably 60% or more. The upper limit can be set to 100% or less, or to 90% or less. By setting these reaction rates, the hardened state of the curable composition layer after exposure can be set more firmly.

本發明中，藉由在顯影前及顯影後的2階段對硬化性組成物層進行曝光，在第1曝光（顯影前的曝光）中能夠適當地對硬化性組成物層進行硬化，在第2曝光（顯影後的曝光）中能夠使硬化性組成物層整體近乎完全硬化。作為結果，即使在小於200℃的低溫條件下亦能夠充分硬化硬化性組成物，從而形成密接性優異，進而耐溶劑性、平坦性及矩形性亦優異之圖案狀的硬化膜。In the present invention, by exposing the curable composition layer in two stages before development and after development, the curable composition layer can be appropriately cured in the first exposure (exposure before development), and the curable composition layer can be appropriately cured in the second exposure. During exposure (exposure after development), the entire curable composition layer can be almost completely hardened. As a result, the curable composition can be sufficiently hardened even under low-temperature conditions of less than 200° C. to form a patterned cured film that is excellent in adhesion and excellent in solvent resistance, flatness, and rectangularity.

＜＜後烘烤＞＞ 在本發明的圖案形成中，可以在顯影製程與第2曝光製程之間、及第2曝光製程後的至少任一期間進行以規定的溫度加熱硬化性組成物層之製程（後烘烤）。後烘烤的加熱溫度小於200℃為較佳，150℃以下為更佳，120℃以下為進一步較佳。又，後烘烤的加熱溫度為45℃以上為較佳，50℃以上為更佳，80℃以上為進一步較佳。尤其，在使用樹脂基板之情況、由有機材料等構成光電轉換層之情況下，加熱溫度為50～120℃為較佳，80～100℃為更佳，80～90℃為進一步較佳。加熱時間能夠適當地選擇，例如為1～10分鐘，2～8分鐘為較佳，3～6分鐘為更佳。＜＜Post-baking＞＞ In the pattern formation of the present invention, a process (post-baking) of heating the curable composition layer at a predetermined temperature may be performed at least in any period between the development process and the second exposure process and after the second exposure process. The heating temperature of the post-baking is preferably less than 200°C, more preferably not more than 150°C, and still more preferably not more than 120°C. In addition, the heating temperature for post-baking is preferably 45°C or higher, more preferably 50°C or higher, and further preferably 80°C or higher. In particular, when a resin substrate is used or the photoelectric conversion layer is composed of an organic material or the like, the heating temperature is preferably 50 to 120°C, more preferably 80 to 100°C, and further preferably 80 to 90°C. The heating time can be appropriately selected, and is, for example, 1 to 10 minutes, preferably 2 to 8 minutes, and more preferably 3 to 6 minutes.

後烘烤可以在大氣下進行，亦可以在低氧環境下進行。從抑制由組成物的氧化引起之劣化等的觀點考慮，後烘烤例如在氧濃度為19體積%以下的低氧環境下進行為較佳，氧濃度為15體積%以下為更佳，5體積%以下為進一步較佳，1體積%以下（指之上為無氧）為特佳。Post-baking can be performed in the atmosphere or in a low-oxygen environment. From the viewpoint of suppressing deterioration caused by oxidation of the composition, etc., post-baking is preferably performed in a low-oxygen environment with an oxygen concentration of 19 volume % or less, for example, more preferably 15 volume % or less, and 5 volume % or less is further preferred, and 1 volume % or less (meaning above means anaerobic) is particularly preferred.

後烘烤能夠使用加熱板或對流式烘箱（熱風循環式乾燥機）、高頻加熱機等加熱機構以連續式或者間歇式進行。另一方面，當在曝光後加熱結構體存在問題時、或硬化性組成物層充分硬化時，可以不進行後烘烤。Post-baking can be performed continuously or intermittently using a heating mechanism such as a heating plate, a convection oven (hot air circulation dryer), or a high-frequency heating machine. On the other hand, when there is a problem in heating the structure after exposure, or when the curable composition layer is sufficiently hardened, post-baking does not need to be performed.

第2曝光製程後（在第2曝光製程後進行後烘烤時為後烘烤後）的圖案狀的硬化膜的厚度為0.1～5.0μm為較佳。下限為0.2μm以上為較佳，0.5μm以上為更佳。上限為4.0μm以下為較佳，2.5μm以下為更佳。硬化膜的圖案的寬度為0.5～20.0μm為較佳。下限為1.0μm以上為較佳，2.0μm以上為更佳。上限為15.0μm以下為較佳，10.0μm以下為更佳。圖案狀的硬化膜的楊氏模數為0.5～20GPa為較佳，2.5～15GPa為更佳。楊氏模數例如能夠使用奈米壓痕法來測量。The thickness of the patterned cured film after the second exposure process (after post-baking when post-baking is performed after the second exposure process) is preferably 0.1 to 5.0 μm. The lower limit is preferably 0.2 μm or more, and more preferably 0.5 μm or more. The upper limit is preferably 4.0 μm or less, and more preferably 2.5 μm or less.
