背景技術  Background art
[0002] 従来より、プリント配線板、液晶表示素子、プラズマディスプレイ、大規模集積回路 、薄型トランジスタ、半導体パッケージ、カラーフィルター、フォトスぺーサ一、リブレジ スト、有機エレクト口ルミネッセンス等における導体回路や電極加工基板等の形成に は、リソグラフィ一法と 、う手法が広く用いられて 、る。  Conventionally, conductor circuits and electrode processing in printed wiring boards, liquid crystal display elements, plasma displays, large-scale integrated circuits, thin transistors, semiconductor packages, color filters, photospacers, rib resisters, organic electorite luminescence, etc. For the formation of a substrate or the like, a lithography method and a technique are widely used.
リソグラフィ一法には、通常(1)ドライフィルムレジスト材 (仮支持フィルム上に感光性 組成物の塗布液を塗布し乾燥させて感光性組成物層を形成し、その感光性組成物 層表面を被覆フィルムで覆った画像形成材料)等を被加工基板上に積層すること〖こ より作製した感光性画像形成材ゃ、 (2)被加工基板上に直接に感光性組成物の塗 布液を塗布し乾燥させて感光性組成物層を形成し、必要に応じてその感光性組成 物層表面を保護層で覆うことにより作製した画像形成材が用いられる。  In the lithography method, usually, (1) a dry film resist material (a photosensitive composition coating solution is applied on a temporary support film and dried to form a photosensitive composition layer, and the surface of the photosensitive composition layer is coated). A photosensitive image forming material produced by laminating an image forming material covered with a coating film) on a substrate to be processed. (2) Applying a coating liquid of the photosensitive composition directly on the substrate to be processed. An image forming material prepared by coating and drying to form a photosensitive composition layer and covering the surface of the photosensitive composition layer with a protective layer as necessary is used.
[0003] そして、以下の(1)〜(3)の手順で画像形成が行われる。(1)被加工基板上の感光 性組成物層を、回路や電極パターンが描かれたマスクフィルムを通して画像露光す る。(2)仮支持フィルム、或いは保護層を剥離し、露光部と非露光部の現像液に対す る溶解性の差を利用して現像処理することによって回路パターンに対応したレジスト 画像を形成する。 (3)前記レジスト画像をレジストとして被加工基板をエッチング加工 、メツキ力卩ェ、或いはソルダー加工等した後、レジスト画像を除去することにより、マス クフィルムに描かれた回路や電極パターンを基板上に形成する。 [0003] Then, image formation is performed according to the following procedures (1) to (3). (1) The photosensitive composition layer on the substrate to be processed is image-exposed through a mask film on which a circuit and an electrode pattern are drawn. (2) The temporary support film or the protective layer is peeled off, and a resist image corresponding to the circuit pattern is formed by developing using the difference in solubility in the developer between the exposed portion and the non-exposed portion. (3) Etching the work substrate using the resist image as a resist After the soldering force or soldering, the resist image is removed to form the circuit or electrode pattern drawn on the mask film on the substrate.
[0004] 一方、近年、露光光源にレーザー光を用いることにより、マスクフィルムを用いずに 、コンピュータ一等のデジタル情報から直接画像を形成するレーザー直接描画法が 、生産性のみならず、解像性や位置精度等の向上も図れることから注目されるに到り 、それに伴い、リソグラフィ一法においてもレーザー光の利用が盛んに研究されてい る。  On the other hand, in recent years, a laser direct drawing method that directly forms an image from digital information such as a computer without using a mask film by using a laser beam as an exposure light source has not only improved productivity but also resolution. As a result, it has been attracting attention because it can improve the performance and the positional accuracy, and accordingly, the use of laser light has been actively studied in the lithography method.
ところで、レーザー光は、紫外力 赤外領域までの種々の光源が知られているが、 画像露光に利用できるレーザー光としては、出力、安定性、感光能力、及びコスト等 の点から、アルゴンイオンレーザー、ヘリウムネオンレーザー、 YAGレーザー、及び 半導体レーザー等の可視力 赤外領域の光を発するものが主力となっている。例え ば、波長 488nmのアルゴンイオンレーザー、波長 532nmの FD—YAGレーザーを 用いたリソグラフィ一法は既に実用化に到っている。  By the way, various light sources up to the ultraviolet and infrared regions are known as laser light, but as laser light that can be used for image exposure, argon ions are used from the viewpoint of output, stability, photosensitive ability, cost, and the like. Lasers, helium neon lasers, YAG lasers, and semiconductor lasers that emit visible light in the infrared region are the mainstays. For example, a lithography method using an argon ion laser with a wavelength of 488 nm and an FD-YAG laser with a wavelength of 532 nm has already been put into practical use.
[0005] し力しながら、従来の感光性組成物は、レーザー光による直接描画法においては、 未だ感度が充分とは言えな力つた。又、近年のレーザー技術の著しい進歩により、青 紫色領域で安定的に発振できる半導体レーザーも利用できるようになったものの、そ の出力が他の可視領域等に比して低いこともあって、それに対応する感光性組成物 の感度、及び現像性等は、直接描画法においてはもとよりリソグラフィ一法において も実用化できるレベルには達して 、な 、のが現状である。  [0005] However, the conventional photosensitive composition has not been sufficiently sensitive in the direct drawing method using a laser beam. In addition, due to significant progress in laser technology in recent years, semiconductor lasers that can oscillate stably in the blue-violet region can be used, but their output is lower than other visible regions, etc. The sensitivity, developability, and the like of the corresponding photosensitive composition have reached a level that can be put into practical use not only by the direct drawing method but also by the lithography method.

There is known a photosensitive composition containing an alkali-soluble modified epoxy acrylate glycolate in which a polyvalent carboxylic acid or an anhydride thereof is added to an acid adduct. Further, the photosensitive composition layer is formed on a substrate by coating the photosensitive composition as a dry film resist material, or the composition coating solution is coated on the substrate and dried to form a photosensitive composition layer. An image forming method is known in which a material is exposed and developed with a high-pressure mercury lamp, a visible laser, or an infrared laser. In addition, for the purpose of improving sensitivity and resolution, α, β unsaturated mono- and mono-oxide compounds and inorganic fine particles or epoxy resin There has been proposed a composition containing an alkali-soluble modified epoxy acrylate resin in which a polyvalent carboxylic acid or an anhydride thereof is added to a carboxylic acid adduct (for example,

Etc. were also insufficient. In particular, the sensitivity of the photosensitive composition corresponding to the blue-violet semiconductor laser was insufficient.

That is, it has been found that those having high sensitivity from ultraviolet to blue-violet light are generally poorly soluble in solvents.

本発明の感光性組成物を構成する (B)成分の光重合開始剤は、感光性組成物が 活性な光線の照射を受けたときに、ラジカル、酸、又は塩基等の活性種を発生し、前 記 (A)成分のエチレン性不飽和基含有化合物を重合に到らしめる活性化合物であ る。本発明の第一の感光性組成物においては、特定構造 (一般式 (1) )を有し、且つ 平均粒子径 0. 001 μ m以上 150 μ m以下である光重合開始剤を含有することが必 須である。本発明の第二の感光性組成物においては、後述する特定構造を有し、且 つ 340〜430nmの波長域に吸収極大を有する光重合開始剤を含有することが必須 である。 [1 - 2- 1 - 1] (B)光重合開始剤の必須成分の平均粒子径 The photopolymerization initiator of the component (B) constituting the photosensitive composition of the present invention generates active species such as radicals, acids, or bases when the photosensitive composition is irradiated with active light. The active compound that brings the ethylenically unsaturated group-containing compound (A) to polymerization. The first photosensitive composition of the present invention contains a photopolymerization initiator having a specific structure (general formula (1)) and an average particle diameter of 0.001 μm to 150 μm. Is indispensable. In the second photosensitive composition of the present invention, it is essential to contain a photopolymerization initiator having a specific structure to be described later and having an absorption maximum in a wavelength region of 340 to 430 nm. [1-2-1-1] (B) Average particle size of essential components of photopolymerization initiator
上記「特定構造」を有する光重合開始剤は前記特許文献 1〜6にお 、て公知の化 合物を含むものである。本発明においては、該光重合開始剤の平均粒子径が 0. 00 1 μ m以上、好ましく ίま 0. 01 m以上であり、 150 m以下、好ましく ίま 50 μ m以下 、更に好ましくは 10 /z m以下、特に好ましくは 5 m以下、とりわけ好ましくは 2 m以 下であることにより、感光性組成物の感度が優れたものとなる。これは、感光性組成 物中に十分量の光重合開始剤が均一に分散されるため、吸光効率が高まり、均一に 感光される組成となったためと考えられる。また、感光性組成物の経時における光重 合開始剤の析出'結晶化も抑制することが出来る点でも優れる。即ち、本発明の第一 の感光性組成物は、溶剤に対して難溶性であることが前提となる。可溶性では、粒子 径の存在する光重合開始剤は組成物中に存在しないからである。尚、本発明に規定 する平均粒子径は、重量平均粒子径又は数平均粒子径を意味するものであり、公知 の測定法により測定することができる。重量平均粒子径、又は数平均粒子径のいず れによる測定値であっても本発明の目的を達成することができる。  The photopolymerization initiator having the “specific structure” includes compounds known in Patent Documents 1 to 6. In the present invention, the average particle diameter of the photopolymerization initiator is 0.001 μm or more, preferably ≧ 0.01 m, more than 150 m, preferably ≧ 50 μm, more preferably 10 / zm or less, particularly preferably 5 m or less, particularly preferably 2 m or less, the sensitivity of the photosensitive composition becomes excellent. This is presumably because a sufficient amount of photopolymerization initiator was uniformly dispersed in the photosensitive composition, so that the light absorption efficiency was increased and the composition was uniformly exposed. It is also excellent in that the photopolymerization initiator can be prevented from precipitating and crystallizing with time in the photosensitive composition. That is, it is premised that the first photosensitive composition of the present invention is hardly soluble in a solvent. This is because the photopolymerization initiator having a particle size is not present in the composition when it is soluble. In addition, the average particle diameter prescribed | regulated to this invention means a weight average particle diameter or a number average particle diameter, and can be measured by a well-known measuring method. The object of the present invention can be achieved even if the measured value is either the weight average particle diameter or the number average particle diameter.
本発明において、上記光重合開始剤の平均粒子径を 0. 001 m以上 150 m以 下とするための方法は、特に限定はないが、例えばペイントコンディショナー、サンド グラインダー、ボールミル、ロールミル、ストーンミル、ジェットミル、ピコミル、ホモジナ ィザ一等を用いて分散処理するのが好ましい。分散処理においては、塗布液、分散 機能を有する有機結合剤、あるいは、特開 2005— 128483号公報に記載される様 に、ノ-オン、カチオン、ァ-オン等の界面活性剤、高分子分散剤等を適当に併用し た系にて処理するのが好ましい。なかでも、好ましい分散処理としてはサンドグライン ダ一が挙げられる。  In the present invention, the method for setting the average particle size of the photopolymerization initiator to 0.001 m or more and 150 m or less is not particularly limited. For example, a paint conditioner, a sand grinder, a ball mill, a roll mill, a stone mill, Dispersion treatment is preferably performed using a jet mill, picomill, homogenizer or the like. In the dispersion treatment, a coating solution, an organic binder having a dispersing function, or a surfactant such as a non-ion, a cation, or a arion as described in JP-A-2005-128483, a polymer dispersion It is preferable to perform the treatment in a system appropriately combined with an agent. Among these, a sand grinder is a preferable dispersion treatment.
また、分散用ビーズとしては、平均粒子径が通常 0. l〜8mm、好ましくは 0. 2〜2 mmの硝子ビーズ又はジルコユアビーズが用いられる。  Further, as the beads for dispersion, glass beads or zirconium beads having an average particle diameter of usually 0.1 to 8 mm, preferably 0.2 to 2 mm are used.
また、分散温度 (気温)は通常 0〜100°Cであり、好ましくは、室温〜 80°Cの範囲で ある。分散時間は分散溶液の組成およびサンドグラインダーの装置サイズ等により、 適正時間が異なるため適宜調整される。  The dispersion temperature (air temperature) is usually from 0 to 100 ° C, and preferably from room temperature to 80 ° C. The dispersion time is appropriately adjusted because the appropriate time varies depending on the composition of the dispersion solution and the size of the sand grinder.
[1 - 2- 1 - 2]光重合開始剤の必須成分の吸収極大の波長域 本発明の感光性組成物を構成する前記光重合開始剤の吸収波長域としては、青 紫色半導体レーザー用の場合は、 340nm以上、好ましくは 345nm以上、更に好ま しくは 350nm以上、特に好ましくは 355nm以上であり、 430nm以下、好ましくは 41 5nm以下に吸収極大を有するものが好ましい。吸収極大が長波長側に寄りすぎると 、黄色灯下で感光しやすくなりセーフライト性が低下する力 または黄色灯下でも感 光しな 、ように感光性組成物層の透明性を上げた場合には、青紫色レーザー光を吸 収しに《なるので感度が低下する。また、吸収極大が短波長側に寄りすぎると、照 射された光エネルギーを効率的に光重合反応に使えないため低感度となる。本発明 の第二の感光性組成物は、上述の吸収極大の波長域に特徴があり、溶剤に対する 溶解性 (即ち、難溶性、可溶性)は問わない。後述する光重合開始剤の必須成分で あるォキシム開始剤のうち、上述の吸収極大を有するものは、一般に溶剤に難溶性 であることが多い。例えば、後に例示する (X— 20)、 (X— 22)等の様な、複数のアル キルォキシル基又は長鎖のアルキルォキシル基を有する化合物群は、可溶性を示 すことがある。 [1-2-1-2] Wavelength range of absorption maximum of essential components of photopolymerization initiator The absorption wavelength region of the photopolymerization initiator constituting the photosensitive composition of the present invention is 340 nm or more, preferably 345 nm or more, more preferably 350 nm or more, particularly preferably 355 nm, for a blue-violet semiconductor laser. The above is preferred, and those having an absorption maximum at 430 nm or less, preferably 415 nm or less are preferred. When the absorption maximum is too close to the long wavelength side, it is easy to sensitize under a yellow light and the safety light property is reduced. Therefore, the sensitivity decreases because it absorbs blue-violet laser light. If the absorption maximum is too close to the short wavelength side, the irradiated light energy cannot be used efficiently for the photopolymerization reaction, resulting in low sensitivity. The second photosensitive composition of the present invention is characterized by the above-mentioned absorption maximum wavelength region, and does not ask for solubility in solvents (that is, hardly soluble or soluble). Of the oxime initiators that are essential components of the photopolymerization initiator described later, those having the above-described absorption maximum are generally poorly soluble in solvents. For example, a group of compounds having a plurality of alkyloxyl groups or long-chain alkyloxyl groups such as (X-20) and (X-22) exemplified later may exhibit solubility.
[0037] 尚、光重合開始剤の吸収極大は、例えば光重合開始剤を約 10— 5モル濃度となるよ うにテトラヒドロフラン溶媒に溶解させた溶液を通常の紫外、可視光吸収スペクトルメ 一ターで測定する等により容易に求められる。 [0037] In addition, the absorption maxima of the photopolymerization initiator is, for example a solution of a photopolymerization initiator by Uni tetrahydrofuran solvent comprising about 10 5 molar conventional ultraviolet, visible light absorption spectrum main one coater It can be easily obtained by measuring or the like.

[0182] 本発明の感光性組成物に用いられる色材は、例えばソルダーレジスト用途である 場合には、ハロゲン原子を含まないものを使用するのが好ましい。 [0182] The colorant used in the photosensitive composition of the present invention is preferably one that does not contain a halogen atom, for example, when used for a solder resist.
また、本発明の感光性組成物の全固形分中に占める色材が、無機、有機顔料の場 合は、顔料の平均粒子径を通常 1 μ m以下、好ましくは 0. 5 μ m以下、更に好ましく は 0. 25 m以下に分散して用いられる。なお、顔料分散には分散性、分散安定性 の向上のために、分散材及び Zまたは分散助剤を併用する事が好ましい。  In the case where the coloring material in the total solid content of the photosensitive composition of the present invention is an inorganic or organic pigment, the average particle diameter of the pigment is usually 1 μm or less, preferably 0.5 μm or less, More preferably, it is used dispersed in 0.25 m or less. For pigment dispersion, it is preferable to use a dispersing agent and Z or a dispersion aid together in order to improve dispersibility and dispersion stability.
分散剤としては、通常、界面活性剤、高分子分散剤などが使用されるが、特に高分 子分散剤を用いると、経時の分散安定性に優れるので好ましい。高分子分散剤とし ては、例えば特開 2005— 126674等に記載の窒素原子含有分散剤が好ましぐこ のような窒素原子含有分散剤としては、例えば、ウレタン系分散剤、窒素原子を含有 するグラフト共重合体、側鎖に 4級アンモニゥム塩基を有する Aブロックと、 4級アンモ -ゥム塩基を有さない Bブロックと力もなる、 A—Bブロック共重合体及び Z又は B— A —Bブロック共重合体等が挙げられる。分散剤は、 1種を単独で使用しても、 2種類以 上を混合しても用いてもょ ヽ。 As the dispersant, surfactants, polymer dispersants and the like are usually used. The use of a co-dispersant is preferable because it is excellent in dispersion stability over time. As the polymer dispersant, for example, a nitrogen atom-containing dispersant described in JP-A-2005-126674 is preferable. As the nitrogen atom-containing dispersant, for example, a urethane-based dispersant and a nitrogen atom are contained. Graft copolymer, A block with quaternary ammonium base in the side chain and B block without quaternary ammonium base, A-B block copolymer and Z or B- A -B Examples thereof include block copolymers. Dispersants can be used alone or in combination of two or more.
本発明の感光性組成物の全固形分中に占める色材の割合は、通常 1〜70重量% 、好ましくは 10〜70重量%、更に好ましくは 20〜60重量%である。色材の含有割合 が少なすぎると、着色力が低くなり、色濃度に対して膜厚が厚くなりすぎて、液晶セル 化の際のギャップ制御などに悪影響を及ぼす。また、逆に色材の含有割合が多すぎ ると、分散安定性が悪化し、再凝集や増粘等の問題が起きる危険性がある。  The proportion of the coloring material in the total solid content of the photosensitive composition of the present invention is usually 1 to 70% by weight, preferably 10 to 70% by weight, and more preferably 20 to 60% by weight. If the content ratio of the color material is too small, the coloring power is lowered, and the film thickness becomes too thick with respect to the color density, which adversely affects the gap control when the liquid crystal cell is formed. On the other hand, if the content of the coloring material is too large, the dispersion stability deteriorates and there is a risk of problems such as re-aggregation and thickening.

When the maximum peak of spectral sensitivity is on the short wavelength side, the sensitivity to laser light with a wavelength of 340 to 430 nm tends to be inferior as a photosensitive composition, whereas when the maximum peak of spectral sensitivity is on the long wavelength side, yellow light Underly safe light tends to be inferior
[0195] 本発明において、分光感度の極大ピークとは、例えば、「フォトポリマー 'テクノロジ 一」(山岡亜夫著、昭和 63年日刊工業新聞社発行、 262頁)等に詳述されている。す なわち、基板表面に光硬化性組成物層を形成した光硬化性画像形成材試料を、分 光感度測定装置を用い、キセノンランプ又はタングステンランプ等の光源力 分光し た光を、横軸方向に露光波長が直線的に、縦軸方向に露光強度が対数的に変化す るように設定して照射して露光する。その後、現像処理することにより、各露光波長の 感度に応じた画像が得られ、その画像高さから画像形成可能な露光エネルギーを算 出し、横軸に波長、縦軸にその露光エネルギーの逆数をプロットすることにより得られ る分光感度曲線における極大ピークを指す。 In the present invention, the maximum peak of spectral sensitivity is described in detail, for example, in “Photopolymer 'Technology I” (Akio Yamaoka, published by Nikkan Kogyo Shimbun, 1988, page 262). The In other words, a photo-curing image-forming material sample having a photo-curable composition layer formed on the substrate surface is subjected to a light sensitivity measurement device using a spectral sensitivity measuring device, and the light is subjected to a horizontal axis direction. Then, exposure is performed by setting the exposure wavelength to be linear and the exposure intensity to change logarithmically in the vertical axis direction. Then, by developing, an image corresponding to the sensitivity of each exposure wavelength is obtained, and the exposure energy capable of forming an image is calculated from the image height. The horizontal axis indicates the wavelength, and the vertical axis indicates the reciprocal of the exposure energy. The maximum peak in the spectral sensitivity curve obtained by plotting.

Exposure is performed by irradiating light separated in a wavelength range of ˜650 nm for 10 seconds, setting the exposure wavelength linearly in the horizontal axis direction and logarithmically changing the exposure intensity in the vertical axis direction.

It was measured. The results are shown in Table 1. That is, the photosensitive composition layer of the obtained image forming material was fixed on an aluminum cylinder having a diameter of 7 cm, and 10-minutes per minute: the center wavelength was 405 nm and the laser output was 5 mW while changing the rotation speed by LOO rotation. Using a laser light source (“NLHV500C” manufactured by Nichia Corporation), scanning exposure was performed while changing the beam scanning interval and scanning speed with an image surface illumination of 2 mW and a beam spot diameter of 20 m. Subsequently, a 1% by weight sodium carbonate aqueous solution at 30 ° C. was sprayed as a developing solution to 0.15 MPa, and a negative image was revealed by spray development in a time twice as long as the minimum developing time. From the obtained image, the amount of exposure required to reproduce a line width of 20 m was determined and used as the sensitivity to the blue-violet laser.

以下に示す方法で分光感度の極大ピークを測定したところ、約 400nmであった。 画像形成材を 50 X 60mmの大きさに切り出したサンプルを、回折分光照射装置( ナルミ社製「RM - 23」)を用い、キセノンランプ (ゥシォ電機社製 Γυΐ 501C」)を光 源として 340〜650nmの波長域で分光した光を、横軸方向に露光波長が直線的に 、縦軸方向に露光強度が対数的に変化するように設定して 10秒間照射して露光した 。次いで、 30°Cの 1重量%炭酸ナトリウム水溶液を現像液として 0. 15MPaとなるよう に吹き付け、最小現像時間の 2倍の時間でスプレー現像することにより、各露光波長 の感度に応じた画像が得られた。その後、その画像高さから、画像形成可能な露光 エネルギーを算出し、横軸に波長、縦軸にその露光エネルギーの逆数をプロットする ことにより得られる分光感度曲線における極大ピークを読み取った。  When the peak of spectral sensitivity was measured by the method shown below, it was about 400 nm. Samples obtained by cutting the image-forming material to a size of 50 x 60 mm were used with a diffraction spectroscopic irradiation device (“RM-23” manufactured by Narumi) and a xenon lamp (Γo ゥ 501C manufactured by Usio Electric Co., Ltd.) as the light source. Exposure was performed by irradiating light dispersed in a wavelength region of 650 nm for 10 seconds with the exposure wavelength set linearly in the horizontal axis direction and the exposure intensity changed logarithmically in the vertical axis direction. Next, an image corresponding to the sensitivity of each exposure wavelength is obtained by spraying a 1% by weight aqueous sodium carbonate solution at 30 ° C to 0.15 MPa as a developing solution and spray developing it for twice the minimum development time. Obtained. Thereafter, the exposure energy capable of forming an image was calculated from the image height, and the maximum peak in the spectral sensitivity curve obtained by plotting the wavelength on the horizontal axis and the reciprocal of the exposure energy on the vertical axis was read.
