Abstract
Description
本発明は、着色感光性樹脂組成物に関する。 The present invention relates to a colored photosensitive resin composition.
着色感光性樹脂組成物は、CCD、CMOSなどのイメージセンサや、液晶表示パネル、エレクトロルミネッセンス、プラズマディスプレイパネルなどのディスプレイ装置に使用されるカラーフィルタの製造用に用いられている。 The colored photosensitive resin composition is used for manufacturing color filters used in image sensors such as CCD and CMOS, and display devices such as liquid crystal display panels, electroluminescence, and plasma display panels.
その中でも特にイメージセンサ用カラーフィルタでは、イメージセンサの高画素化に伴い、高解像度で膜厚の薄いものが求められている。単に膜厚を薄くすると色濃度が薄くなるため、充分な色濃度を確保するためには、カラーフィルタの画素を形成する感光性樹脂組成物中の顔料濃度を高くする必要がある。しかしながら、高い濃度で顔料を含む着色感光性樹脂組成物を用いて膜を形成して、所定の形状のマスクを用いて露光し、不要部分を現像液により除去してカラーフィルタを製造した場合に、現像液により除去できなかったもの(残渣)が多く残るという問題点があった(例えば、特許文献1参照。)。 Among them, in particular, color filters for image sensors are required to have high resolution and a thin film thickness as the number of pixels of the image sensor increases. If the film thickness is simply reduced, the color density is reduced. Therefore, in order to ensure a sufficient color density, it is necessary to increase the pigment density in the photosensitive resin composition forming the pixels of the color filter. However, when a color filter is produced by forming a film using a colored photosensitive resin composition containing a pigment at a high concentration, exposing using a mask having a predetermined shape, and removing unnecessary portions with a developer. There is a problem that a large amount of residue (residue) that cannot be removed by the developer remains (see, for example, Patent Document 1).
そこで、高い濃度で顔料を含んでいても現像残渣の残り難いカラーフィルタの製造用の着色感光性樹脂組成物が種々検討されており、着色剤、バインダー樹脂、光重合性化合物、光重合開始剤、溶剤からなる着色感光性樹脂組成物において、光重合性化合物がエトキシ化ジペンタエリスリトールヘキサアクリレートおよびエトキシ化ペンタエリスリトールからなるものが提案されている(例えば、特許文献2参照。)が、イメージセンサ用カラーフィルタの製造における現像後の残渣を改善するにはまだ改良の余地があった。 Accordingly, various types of colored photosensitive resin compositions for producing color filters in which development residues are difficult to remain even when pigments are contained at a high concentration have been studied. Colorants, binder resins, photopolymerizable compounds, photopolymerization initiators In a colored photosensitive resin composition comprising a solvent, a photopolymerizable compound comprising ethoxylated dipentaerythritol hexaacrylate and ethoxylated pentaerythritol has been proposed (for example, see Patent Document 2). There was still room for improvement in improving the post-development residue in the production of color filters for use.
本発明の目的は、高い濃度で顔料を含んでいても、カラーフィルタの製造における現像後の残渣が少ない、新たな着色感光性樹脂組成物を提供することにある。 An object of the present invention is to provide a new colored photosensitive resin composition that contains little pigment after development in the production of a color filter even if it contains a pigment at a high concentration.

本発明の着色感光性樹脂組成物を用いて、膜厚の薄いカラーフィルタを製造すると、現像後の残渣が少なくなり、色純度が高く、製造不良品の少ないカラーフィルタを製造することができる。 When a color filter having a thin film thickness is produced using the colored photosensitive resin composition of the present invention, a residue after development is reduced, a color filter having high color purity and few defective products can be produced.

本発明の着色感光性樹脂組成物を調製する方法としては、例えば、溶剤(E)中において分散剤を併存させて、顔料などの着色剤を分散させることにより、着色剤の分散液を調製し、さらに、溶剤に溶解させた(B)バインダー樹脂、(C)光重合性化合物、(D)光重合開始剤および必要によりその他の添加剤等を溶解させ、前記の(A)着色剤の分散液と混合し、必要によりさらに溶剤を添加する方法などが挙げられる。 As a method for preparing the colored photosensitive resin composition of the present invention, for example, a dispersion of a colorant is prepared by dispersing a colorant such as a pigment in the solvent (E) together with a dispersant. Furthermore, (B) binder resin, (C) photopolymerizable compound, (D) photopolymerization initiator and other additives as necessary dissolved in a solvent are dissolved, and the above-mentioned (A) colorant is dispersed. The method of mixing with a liquid and adding a solvent further as needed is mentioned.
また、本発明の着色感光性樹脂組成物は、通常、容器に封入して、流通、保管に供される。 In addition, the colored photosensitive resin composition of the present invention is usually enclosed in a container and distributed and stored.
本発明の着色感光性樹脂組成物を用いたイメージセンサ用カラーフィルタの一般的な製造法は次の通りである。本発明の着色感光性樹脂組成物を基板上に塗布・乾燥する工程、得られた乾燥塗布膜にi線ステッパー等でパターン露光する工程、露光後にアルカリ現像する工程、次に加熱処理する工程を順次行い、各色(3色あるいは4色)ごとに前記工程を順次繰り返して画素を形成することによりカラーフィルタが得られる。 A general method for producing a color filter for an image sensor using the colored photosensitive resin composition of the present invention is as follows. A step of applying and drying the colored photosensitive resin composition of the present invention on a substrate, a step of pattern exposure of the obtained dry coating film with an i-line stepper, a step of alkali development after exposure, and a step of heat treatment A color filter is obtained by sequentially performing the above steps for each color (3 colors or 4 colors) to form pixels.
より具体的には、本発明の着色感光性樹脂組成物を、スピンコーター等により、適当な基板上に乾燥時の膜厚が一般的に0.1〜5μm、好ましくは0.2〜2μmになるように塗布し、100℃のオーブンに3分間放置し平滑な塗膜を得る。
基板としては、特に限定されないが、ガラス板、プラスチックス板、アルミ板、撮像素子用シリコンウエハ等の電子部品の基板、さらには透明樹脂板、樹脂フィルム、ブラウン管表示面、撮像感の受光面、CCD、BBD、CID、BASIS等の固体撮像素子が形成されたウエハー、薄膜半導体を用いた密着型イメージセンサ、液晶ディスプレイ面、カラー電子写真用感光体、エレクトロクロミィー(EC)表示装置の基板等が挙げられる。また、基板にカラーフィルタ層との接着性を向上させるために高密着処理を施すことが好ましい。具体的には、基板上に予めシランカップリング剤等で薄く塗布した後に着色感光性樹脂組成物のパターンを形成するか、あるいは予め着色感光性樹脂組成物中にシランカップリング剤を含有させてもよい。
More specifically, the colored photosensitive resin composition of the present invention is dried on a suitable substrate by a spin coater or the like so that the film thickness when dried is generally 0.1 to 5 μm, preferably 0.2 to 2 μm. Then, it is left in an oven at 100 ° C. for 3 minutes to obtain a smooth coating film.
The substrate is not particularly limited, but is a glass plate, a plastic plate, an aluminum plate, a substrate for an electronic component such as a silicon wafer for an image sensor, a transparent resin plate, a resin film, a cathode ray tube display surface, a light receiving surface for imaging feeling, Wafers on which solid-state image sensors such as CCD, BBD, CID, and BASIS are formed, contact image sensors using thin film semiconductors, liquid crystal display surfaces, color electrophotographic photoreceptors, substrates for electrochromy (EC) display devices, etc. Is mentioned. Further, it is preferable to perform a high adhesion treatment to improve the adhesion to the color filter layer on the substrate. Specifically, after a thin coating with a silane coupling agent or the like is applied on the substrate in advance, a pattern of the colored photosensitive resin composition is formed, or the colored photosensitive resin composition is previously incorporated with a silane coupling agent. Also good.
なお、基板上に段差がある場合は、その段差を解消し塗設面を平滑にするための平坦化膜を基板上に塗設した後、本発明の着色感光性樹脂組成物を塗布することができる。例えば、CCDなどのイメージセンサのセンサ部はシリコン基板上に受光量に応じて電子を発生させる光電子変換部(フォトダイオード)とその発生した電子を出力する為の読み出しゲート部とで構成されているが、読み出しゲート部に光が当たるとノイズの原因となり正確なデータが出力されないため、読み出しゲート部の上部には遮光膜層が形成されており、遮光膜層を持たないフォトダイオード部との間で段差が生じている場合がある。このような段差上にカラーレジストを塗布し、直接カラーフィルタを形成すると光路長が長くなるため画像が暗く、また集光性も劣るようになる。これを改善する為、その段差を埋める目的で透明な平坦化膜をCCDとカラーフィルタとの間に形成することが好ましい。この平坦化膜の材料としては、本発明におけるような感光性樹脂組成物、アクリル系、エポキシ系等の熱硬化性樹脂や光硬化性樹脂等が挙げられる。 If there is a step on the substrate, apply the colored photosensitive resin composition of the present invention after coating the substrate with a planarizing film for eliminating the step and smoothing the coating surface. Can do. For example, a sensor unit of an image sensor such as a CCD is composed of a photoelectric conversion unit (photodiode) that generates electrons on a silicon substrate according to the amount of received light, and a readout gate unit for outputting the generated electrons. However, if light hits the readout gate part, it causes noise and accurate data is not output.Therefore, a light shielding film layer is formed on the upper part of the readout gate part, and between the photodiode part without the light shielding film layer. There may be a level difference. When a color resist is applied on such a step and a color filter is directly formed, the optical path length becomes long, so that the image becomes dark and the light condensing property becomes inferior. In order to improve this, it is preferable to form a transparent flattening film between the CCD and the color filter in order to fill the step. Examples of the material for the planarizing film include a photosensitive resin composition as in the present invention, an acrylic-based, epoxy-based thermosetting resin, a photo-curable resin, and the like.
感光性樹脂組成物を塗布した後、溶媒を除去して乾燥塗布膜を得るため、通常、減圧乾燥やプリベークが行われる。減圧乾燥の方法としては、例えば、塗布物を、0.1〜100Torrの圧力で、50〜120℃の温度におくことにより行う方法がある。プリベークの方法としては、高温の空気などによる加熱乾燥、ホットプレート等による加熱乾燥(80〜140℃、50〜200秒)などの方法がある。 After applying the photosensitive resin composition, in order to obtain a dry coating film by removing the solvent, drying under reduced pressure or pre-baking is usually performed. As a method for drying under reduced pressure, for example, there is a method in which the coated material is placed at a temperature of 50 to 120 ° C. at a pressure of 0.1 to 100 Torr. Examples of the pre-baking method include heat drying using high-temperature air and the like, and heat drying using a hot plate or the like (80 to 140 ° C., 50 to 200 seconds).
また、現像後に得られたパターンを、十分硬化させて機械強度を高め永久膜とするためにポストベークが行われる。例えば、3色のカラーフィルタの製造に際しては、最初に形成されたパターンは、その後、他色の着色感光性樹脂組成物の塗布、露光、現像を2度受ける。この際に、塗布された着色感光性樹脂組成物との混色、露光、現像によるパターンの欠落が生じないようにポストベークを行うものである。このポストベークはプリベーク同様の方法が用いられるが、プリベークの条件よりも、高温、長時間で行われる。例えば、100〜250℃、1〜60分間行われる。 In addition, post-baking is performed in order to sufficiently cure the pattern obtained after development to increase the mechanical strength and form a permanent film. For example, in the production of a three-color filter, the first formed pattern is then subjected twice to the application of a colored photosensitive resin composition of another color, exposure, and development. At this time, post-baking is performed so as not to cause pattern omission due to color mixing, exposure, and development with the applied colored photosensitive resin composition. This post-baking uses the same method as pre-baking, but is performed at a higher temperature and for a longer time than the pre-baking conditions. For example, it is performed at 100 to 250 ° C. for 1 to 60 minutes.
着色感光性樹脂組成物の現像に使用する現像液は特に制限はなく、従来公知の現像液を使用することができる。中でも、テトラメチルアンモニウムハイドロキサイド(TMAH)などの4級アンモニウム塩類の有機アルカリ系水溶液が好ましい。 There is no restriction | limiting in particular in the developing solution used for development of a coloring photosensitive resin composition, A conventionally well-known developing solution can be used. Among these, an organic alkaline aqueous solution of quaternary ammonium salts such as tetramethylammonium hydroxide (TMAH) is preferable.
ここで、本発明のカラーフィルタを具備するイメージセンサは、例えば、上記のとおり、基板上に形成されたセンサ部上に平坦化膜を形成し、その上に本発明のカラーフィルタを形成した後、レンズ材を塗布し、フォトリソグラフィ工程と熱処理によりレンズパターンをパターニングし、次に、全面をエッチバックしてオンチップレンズを形成することにより製造することができる。 Here, in the image sensor including the color filter of the present invention, for example, as described above, after the planarization film is formed on the sensor portion formed on the substrate and the color filter of the present invention is formed thereon, It can be manufactured by applying a lens material, patterning a lens pattern by a photolithography process and heat treatment, and then etching back the entire surface to form an on-chip lens.
