Abstract
Description
本発明は、感放射線性樹脂組成物、層間絶縁膜およびマイクロレンズ、ならびにそれらの製造方法に関する。 The present invention relates to a radiation-sensitive resin composition, an interlayer insulating film and a microlens, and methods for producing them.
薄膜トランジスタ(以下、「TFT」と記す。)型液晶表示素子や磁気ヘッド素子、集積回路素子、固体撮像素子などの電子部品には、一般に層状に配置される配線の間を絶縁するために層間絶縁膜が設けられている。層間絶縁膜を形成する材料としては、必要とするパターン形状を得るための工程数が少なくしかも十分な平坦性を有するものが好ましいことから、感放射線性樹脂組成物が幅広く使用されている(例えば、特許文献1および特許文献2参照。)。
上記電子部品のうち、例えばTFT型液晶表示素子は、上記の層間絶縁膜の上に、透明電極膜を形成し、さらにその上に液晶配向膜を形成する工程を経て製造されるため、層間絶縁膜は、透明電極膜の形成工程において高温条件に曝されたり、電極のパターン形成に使用されるレジストの剥離液に曝されることとなるため、これらに対する十分な耐性が必要となる。
また近年、TFT型液晶表示素子においては、大画面化、高輝度化、高精細化、高速応答化、薄型化等の動向にあり、それに用いられる層間絶縁膜形成用組成物としては高感度であり、形成される層間絶縁膜には低誘電率、高透過率等において、従来にも増して高性能が要求されている。
In an electronic component such as a thin film transistor (hereinafter referred to as “TFT”) type liquid crystal display element, magnetic head element, integrated circuit element, solid-state imaging element, etc., an interlayer insulation is generally used to insulate between wirings arranged in layers. A membrane is provided. As a material for forming the interlayer insulating film, a material having a small number of steps for obtaining a required pattern shape and sufficient flatness is preferable, and therefore, a radiation sensitive resin composition is widely used (for example, , See Patent Document 1 and Patent Document 2.)
Among the electronic components, for example, a TFT type liquid crystal display element is manufactured through a process of forming a transparent electrode film on the interlayer insulating film and further forming a liquid crystal alignment film on the interlayer insulating film. Since the film is exposed to a high temperature condition in the transparent electrode film forming process or exposed to a resist stripping solution used for forming an electrode pattern, sufficient resistance to these is required.
In recent years, TFT-type liquid crystal display elements have been in the trend of larger screens, higher brightness, higher definition, faster response, thinner thickness, etc., and the composition for forming an interlayer insulating film used therefor has high sensitivity. In addition, the interlayer insulating film to be formed is required to have higher performance than ever in terms of low dielectric constant and high transmittance.
一方、ファクシミリ、電子複写機、固体撮像素子等のオンチップカラーフィルターの結像光学系あるいは光ファイバコネクタの光学系材料として3〜100μm程度のレンズ径を有するマイクロレンズ、またはそれらのマイクロレンズを規則的に配列したマイクロレンズアレイが使用されている。
マイクロレンズまたはマイクロレンズアレイの形成には、レンズに相当するレジストパターンを形成した後、加熱処理することによってメルトフローさせ、そのままレンズとして利用する方法や、メルトフローさせたレンズパターンをマスクにしてドライエッチングにより下地にレンズ形状を転写させる方法等が知られている。前記レンズパターンの形成には、感放射線性樹脂組成物が幅広く使用されている(例えば、特許文献3および特許文献4参照。)。
On the other hand, a microlens having a lens diameter of about 3 to 100 μm or an optical system material for an on-chip color filter such as a facsimile, an electronic copying machine, a solid-state image sensor, or the like is defined as an optical system material. An array of microlenses is used.
To form a microlens or microlens array, a resist pattern corresponding to the lens is formed and then melt-flowed by heat treatment and used as it is as a lens, or by using the melt-flowed lens pattern as a mask and drying. A method of transferring a lens shape to a base by etching is known. For the formation of the lens pattern, a radiation sensitive resin composition is widely used (see, for example, Patent Document 3 and Patent Document 4).
ところで、上記のようなマイクロレンズまたはマイクロレンズアレイが形成された素子はその後、配線形成部分であるボンディングパッド上の各種絶縁膜を除去するために、平坦化膜およびエッチング用レジスト膜を塗布し、所望のマスクを用いて露光、現像してボンディングパッド部分のエッチングレジストを除去し、次いで、エッチングにより平坦化膜や各種絶縁膜を除去してボンディングパッド部分を露出させる工程に供される。そのためマイクロレンズまたはマイクロレンズアレイには、平坦化膜およびエッチングレジストの塗膜形成工程ならびにエッチング工程において、耐溶剤性や耐熱性が必要となる。 By the way, the element in which the microlens or the microlens array as described above is formed is then applied with a planarizing film and an etching resist film in order to remove various insulating films on the bonding pad which is a wiring forming portion. Exposure and development are performed using a desired mask to remove the etching resist in the bonding pad portion, and then the step is performed to remove the planarizing film and various insulating films by etching to expose the bonding pad portion. Therefore, the microlens or the microlens array needs to have solvent resistance and heat resistance in the flattening film and etching resist coating forming process and the etching process.
このようなマイクロレンズを形成するために用いられる感放射線性樹脂組成物は、高感度であり、また、それから形成されるマイクロレンズが所望の曲率半径を有するものであり、高耐熱性、高透過率であること等が要求される。
また、このようにして得られる層間絶縁膜やマイクロレンズは、これらを形成する際の現像工程において、現像時間が最適時間よりわずかでも過剰となると、パターンと基板との間に現像液が浸透して剥がれが生じやすくなるため、現像時間を厳密に制御する必要があり、製品の歩留まりの点で問題があった。
このように、層間絶縁膜やマイクロレンズを感放射線性樹脂組成物から形成するにあたっては、組成物としては高感度であることが要求され、また形成工程中の現像工程において現像時間が所定時間より過剰となった場合でもパターンの剥がれが生じずに良好な密着性を示し、かつそれから形成される層間絶縁膜には高耐熱性、高耐溶剤性、低誘電率、高透過率等が要求され、一方、マイクロレンズを形成する場合にはマイクロレンズとして良好なメルト形状(所望の曲率半径)、高耐熱性、高耐溶剤性、高透過率が要求されることとなるが、そのような要求を満足する感放射線性樹脂組成物は従来知られていなかった。
The radiation-sensitive resin composition used to form such a microlens has high sensitivity, and the microlens formed therefrom has a desired radius of curvature, and has high heat resistance and high transmittance. It is required to be a rate.
In addition, the interlayer insulating film and the microlens thus obtained can penetrate between the pattern and the substrate if the development time is slightly longer than the optimum time in the development process when forming them. Therefore, it is necessary to strictly control the development time, and there is a problem in terms of product yield.
As described above, in forming the interlayer insulating film and the microlens from the radiation-sensitive resin composition, the composition is required to have high sensitivity, and the developing time in the developing process during the forming process is longer than a predetermined time. Even if it becomes excessive, the pattern does not peel off and shows good adhesion, and the interlayer insulating film formed therefrom is required to have high heat resistance, high solvent resistance, low dielectric constant, high transmittance, etc. On the other hand, when forming a microlens, a good melt shape (desired radius of curvature), high heat resistance, high solvent resistance, and high transmittance are required as the microlens. A radiation-sensitive resin composition satisfying the above has not been conventionally known.
本発明は以上のような事情に基づいてなされたものである。それ故、本発明の目的は、高い感放射線感度を有し、現像工程において最適現像時間を越えてもなお良好なパターン形状を形成できるような現像マージンを有し、密着性に優れたパターン状薄膜を容易に形成することができる感放射線性組成物を提供することにある。
本発明の他の目的は、層間絶縁膜の形成に用いる場合にあっては高耐熱性、高耐溶剤性、高透過率、低誘電率の層間絶縁膜を形成でき、またマイクロレンズの形成に用いる場合にあっては高い透過率と良好なメルト形状を有するマイクロレンズを形成しうる感放射線性樹脂組成物を提供することにある。
本発明のさらに別の目的は、上記感放射線性樹脂組成物を用いて層間絶縁膜およびマイクロレンズを形成する方法を提供することにある。
本発明のさらに他の目的は、本発明の方法により形成された層間絶縁膜およびマイクロレンズを提供することにある。

Examples of the ultraviolet rays include g-line (wavelength 436 nm), i-line (wavelength 365 nm), and the like. Examples of the far ultraviolet rays include KrF excimer laser. Examples of X-rays include synchrotron radiation. Examples of the charged particle beam include an electron beam.
Among these, ultraviolet rays are preferable, and radiation including g-line and / or i-line is particularly preferable.
The exposure amount, 50~1,500J / m 2 In the case of forming an interlayer insulating film, in the case of forming a micro-lens is preferably set to 50~2,000J / m 2.
(3)現像工程
現像処理に用いられる現像液としては、例えば水酸化ナトリウム、水酸化カリウム、炭酸ナトリウム、ケイ酸ナトリウム、メタケイ酸ナトリウム、アンモニア、エチルアミン、n−プロピルアミン、ジエチルアミン、ジエチルアミノエタノール、ジ−n−プロピルアミン、トリエチルアミン、メチルジエチルアミン、ジメチルエタノールアミン、トリエタノールアミン、テトラメチルアンモニウムヒドロキシド、テトラエチルアンモニウムヒドロキシド、ピロール、ピペリジン、1,8−ジアザビシクロ〔5,4,0〕−7−ウンデセン、1,5−ジアザビシクロ〔4,3,0〕−5−ノナン等のアルカリ(塩基性化合物)の水溶液を用いることができる。また、上記のアルカリの水溶液にメタノール、エタノール等の水溶性有機溶媒や界面活性剤を適当量添加した水溶液、または本発明の組成物を溶解する各種有機溶媒を現像液として使用することができる。さらに、現像方法としては、液盛り法、ディッピング法、揺動浸漬法、シャワー法等の適宜の方法を利用することができる。このときの現像時間は、組成物の組成によって異なるが、例えば30〜120秒間とすることができる。
なお、従来知られている感放射線性樹脂組成物は、現像時間が最適値から20〜25秒程度超過すると形成したパターンに剥がれが生じるため現像時間を厳密に制御する必要があったが、本発明の感放射線性樹脂組成物の場合、最適現像時間からの超過時間が30秒以上となっても良好なパターン形成が可能であり、製品歩留まり上の利点がある。
(3) Development process Examples of the developer used in the development process include sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, sodium metasilicate, ammonia, ethylamine, n-propylamine, diethylamine, diethylaminoethanol, di-acid. N-propylamine, triethylamine, methyldiethylamine, dimethylethanolamine, triethanolamine, tetramethylammonium hydroxide, tetraethylammonium hydroxide, pyrrole, piperidine, 1,8-diazabicyclo [5,4,0] -7-undecene An aqueous solution of an alkali (basic compound) such as 1,5-diazabicyclo [4,3,0] -5-nonane can be used. In addition, an aqueous solution obtained by adding an appropriate amount of a water-soluble organic solvent such as methanol or ethanol or a surfactant to the above aqueous alkali solution, or various organic solvents that dissolve the composition of the present invention can be used as a developing solution. Furthermore, as a developing method, an appropriate method such as a liquid piling method, a dipping method, a rocking dipping method, a shower method, or the like can be used. The development time at this time varies depending on the composition of the composition, but can be, for example, 30 to 120 seconds.
In addition, the conventionally known radiation-sensitive resin composition has been required to strictly control the development time because the formed pattern peels when the development time exceeds about 20 to 25 seconds from the optimum value. In the case of the radiation-sensitive resin composition of the invention, good pattern formation is possible even when the excess time from the optimum development time is 30 seconds or more, and there is an advantage in product yield.
(4)加熱工程
上記のように実施した(3)現像工程後に、パターニングされた薄膜に対して、好ましくは例えば流水洗浄によるリンス処理を行い、さらに、好ましくは高圧水銀灯などによる放射線を全面に照射(後露光)することにより、当該薄膜中に残存する1,2−キノンジアジト化合物の分解処理を行った後、この薄膜を、ホットプレート、オーブン等の加熱装置により加熱処理(ポストベーク処理)することにより、当該薄膜の硬化処理を行う。上記後露光工程における露光量は、好ましくは2,000〜5,000J/m2程度である。また、この硬化処理における焼成温度は、例えば120〜250℃である。加熱時間は、加熱機器の種類により異なるが、例えばホットプレート上で加熱処理を行う場合には5〜30分間、オーブン中で加熱処理を行う場合には30〜90分間とすることができる。この際に、2回以上の加熱工程を行うステップベーク法等を用いることもできる。
このようにして、目的とする層間絶縁膜またはマイクロレンズに対応する、パターン状薄膜を基板の表面上に形成することができる。
上記のようにして形成された層間絶縁膜およびマイクロレンズは、後述の実施例から明らかにされるように、密着性、耐熱性、耐溶剤性、および透明性等に優れるものである。
(4) Heating step (3) Performed as described above (3) After the development step, the patterned thin film is preferably rinsed, for example, by washing with running water, and more preferably irradiated with radiation from a high-pressure mercury lamp or the like. (After post-exposure), the 1,2-quinonediadito compound remaining in the thin film is decomposed, and then the thin film is heated (post-baked) with a heating device such as a hot plate or an oven. Then, the thin film is cured. The exposure amount in the post-exposure step is preferably about 2,000 to 5,000 J / m 2 . Moreover, the baking temperature in this hardening process is 120-250 degreeC, for example. Although heating time changes with kinds of heating apparatus, for example, when performing heat processing on a hotplate, it can be set to 30 to 90 minutes when performing heat processing in oven, for example. At this time, a step baking method or the like in which a heating process is performed twice or more can also be used.
In this way, a patterned thin film corresponding to the target interlayer insulating film or microlens can be formed on the surface of the substrate.
The interlayer insulating film and the microlens formed as described above are excellent in adhesion, heat resistance, solvent resistance, transparency, and the like, as will be apparent from the examples described later.

上記のようにして形成された本発明の層間絶縁膜は、基板への密着性が良好であり、耐溶剤性および耐熱性に優れ、高い透過率を有し、誘電率が低いものであり、電子部品の層間絶縁膜として好適に使用できる。

上記のようにして形成された本発明のマイクロレンズは、基板への密着性が良好であり、耐溶剤性および耐熱性に優れ、かつ高い透過率と良好なメルト形状を有するものであり、固体撮像素子のマイクロレンズとして好適に使用できる。
なお、本発明のマイクロレンズの形状は、図1(a)に示したように、半凸レンズ形状となる。
Interlayer Insulating Film The interlayer insulating film of the present invention formed as described above has good adhesion to the substrate, excellent solvent resistance and heat resistance, high transmittance, and low dielectric constant. Therefore, it can be suitably used as an interlayer insulating film of electronic parts.
The microlens of the present invention formed as described above has good adhesion to the substrate, excellent solvent resistance and heat resistance, and has high transmittance and a good melt shape. It can be suitably used as a microlens for a solid-state imaging device.
