Description
本発明は基板上の表面粗化方法に係わり、この方法は特にLED等の光取り出し層に適用することができる。 The present invention relates to a surface roughening method on a substrate, and this method can be applied particularly to a light extraction layer such as an LED.
近年、LED技術が利用されている。そして、その発光効率の向上のための技術として光取り出し層の研究が行われている。
LED等の光取り出し層としては有機EL素子内部の発光層と基板の間に、光散乱層を設ける手法が提案されている(特許文献1参照)。光散乱層としては、透明な樹脂に、該樹脂とは屈折率の異なる微粒子が分散されたものが用いられる。発光部で発光した光は、光散乱層により散乱されて、様々な方向に進行方向を変える。多重散乱の結果、空気との界面において全反射角内の角度域に入射した光が取り出されうる。光散乱層においては、光の進行方向がランダムに変化するため、微粒子のサイズ分布は広く、微粒子の配列はランダムであり、また微粒子の体積分率は大きいことが好ましい。ここで微粒子のサイズ分布が狭いと、或いは微粒子の体積分率が小さいと、光散乱層の散乱能が低くなってしまう。しかし、微粒子のサイズ分布が広いと樹脂中で微粒子を理想的に配列させることが困難となり、また微粒子のサイズ分布が広い場合に体積分率を大きくしようとすると、光散乱層の平坦性が著しく低下し、それにより薄膜構造である発光部の平坦性が損なわれて、発光素子の信頼性が大きく低下する。
In recent years, LED technology has been utilized. Research on the light extraction layer has been conducted as a technique for improving the luminous efficiency.
As a light extraction layer for an LED or the like, a method of providing a light scattering layer between a light emitting layer inside an organic EL element and a substrate has been proposed (see Patent Document 1). As the light scattering layer, a transparent resin in which fine particles having a refractive index different from that of the resin are dispersed is used. The light emitted from the light emitting unit is scattered by the light scattering layer and changes the traveling direction in various directions. As a result of multiple scattering, light incident on an angle region within the total reflection angle at the interface with air can be extracted. In the light scattering layer, the traveling direction of light randomly changes, so that the size distribution of the fine particles is wide, the arrangement of the fine particles is random, and the volume fraction of the fine particles is preferably large. Here, when the size distribution of the fine particles is narrow or the volume fraction of the fine particles is small, the scattering ability of the light scattering layer is lowered. However, if the size distribution of the fine particles is wide, it becomes difficult to ideally arrange the fine particles in the resin, and if the volume fraction is wide when the size distribution of the fine particles is wide, the flatness of the light scattering layer is remarkably high. As a result, the flatness of the light emitting part having a thin film structure is impaired, and the reliability of the light emitting element is greatly reduced.
また、反射層と、前記反射層上に形成された、変動係数が10%以下の微粒子および前記微粒子と屈折率の異なるマトリックスを含む3次元回折層とを備え、前記微粒子の3次元回折層の体積に対する体積分率が50%以上であり、前記微粒子が配列して短距離周期性を有する第一の領域を形成し、さらにその第一の領域がランダムな向きで隣接して集合した第二の領域を形成していることを特徴とする、光取り出し層が開示されている(特許文献2参照)。 A reflective layer; and a three-dimensional diffraction layer formed on the reflective layer and including a fine particle having a coefficient of variation of 10% or less and a matrix having a refractive index different from that of the fine particle. The volume fraction with respect to the volume is 50% or more, the fine particles are arranged to form a first region having a short-range periodicity, and the first region is gathered adjacently in a random direction. A light extraction layer is disclosed (see Patent Document 2).

In particular, the present invention utilizes a layer in which an inorganic substance and an organic substance are mixed on the substrate, and utilizes a difference in etching rate between the inorganic and organic oxygen gas to etch the surface of the substrate where oxygen gas is etched and the surface roughness not etched. The surface of the substrate can be roughened by etching with oxygen gas or fluorine-based gas using the surface roughened layer as a mask, for example, fine irregularities can be formed on the substrate, It is another object of the present invention to provide a method that can similarly roughen the surface by wet etching using an acidic aqueous solution instead of gas etching.

本発明により、基板の表面を粗化する新規な方法が提供される。特に、本発明の方法は、基板上に無機物と有機物が混在する層を利用して、無機物と有機物の酸素ガスのエッチング速度差を利用することができるので、基板の表面に酸素ガスがエッチングされる部分とエッチングされない表面粗化層とを形成することができ、そして更にその表面粗化層をマスクとして酸素ガス又はフッ素系ガスのエッチングにより基板表面を粗化、例えば基板上に微細な凹凸を形成することができ、また、本発明の方法に従うと、ガスエッチングに変えて酸性水溶液を用いる湿式エッチングによっても同様に表面を粗化することができる。 The present invention provides a novel method for roughening the surface of a substrate.

And a surface roughened layer that is not etched, and the surface roughened layer is used as a mask to roughen the substrate surface by etching with oxygen gas or fluorine-based gas.

According to the method of the present invention, the surface can be similarly roughened by wet etching using an acidic aqueous solution instead of gas etching.
有機ELディスプレイでは、ガラスや透明プラスチック等の基板上にITO電極、正孔注入層、正孔輸送層、発光層、電子輸送層、電子注入層、電極が形成される。
また、サファイア上にN型半導体、発光域、P型半導体、ITO電極、SiO2層が形成される。
In an organic EL display, an ITO electrode, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and an electrode are formed on a substrate such as glass or transparent plastic.
Further, an N-type semiconductor, a light emitting region, a P-type semiconductor, an ITO electrode, and a SiO 2 layer are formed on sapphire.
本発明ではこれらの光取り出し層として使われるガラスや透明プラスチックやSiO2層などの表面を粗化、例えば微細な凹凸を形成することで光の反射を低減することが可能であり、それにより発光効率を向上させることができる。 In the present invention, it is possible to reduce the reflection of light by roughening the surface of the glass, transparent plastic, SiO 2 layer, etc. used as the light extraction layer, for example, by forming fine irregularities. Efficiency can be improved.
従来法として光取り出し層に用いられる基板に無機粒子等を付着させる手法があるが密着性が問題となっていた。本発明はそれら手法とは異なり、基板表面を物理的なエッチングにより粗化、例えば凹凸等を形成させるものである。 As a conventional method, there is a method of attaching inorganic particles or the like to a substrate used for a light extraction layer, but adhesion has been a problem. In the present invention, unlike those methods, the substrate surface is roughened by physical etching, for example, irregularities are formed.
本発明は粗化させる基板上に又は基板より上方の層上に無機粒子(a1)と有機樹脂(a2)を含む組成物(a3)を塗布し乾燥と硬化を行って有機樹脂層(A)を形成する第1工程と、それに続く該基板の上方からガスでエッチングを行って同基板の表面を粗化する第2工程とを含んでいる。有機樹脂層(A)に含まれる無機粒子(a1)と有機樹脂(a2)との酸素ガスのエッチング速度差を利用して、有機樹脂層(A)に凹凸を形成する。有機樹脂層(A)の凹凸はその後、更に続けられる酸素ガスのエッチング、又はその他のガス(フッ素系ガス、塩素系ガス)によって基板表面にエッチングされる部分とエッチングされない部分が生じ凹凸が形成される。
場合によっては形成された凹凸が更にエッチングされて基板の下方に向かってエッチング層が形成される。
乾燥と硬化は同時に行うことも、乾燥をした後に硬化を行うこともできる。
In the present invention, a composition (a3) containing inorganic particles (a1) and an organic resin (a2) is applied on a substrate to be roughened or on a layer above the substrate, dried and cured, and then an organic resin layer (A). And a subsequent second step of roughening the surface of the substrate by etching with gas from above the substrate. Concavities and convexities are formed in the organic resin layer (A) using the etching rate difference of oxygen gas between the inorganic particles (a1) and the organic resin (a2) contained in the organic resin layer (A). Then, the unevenness of the organic resin layer (A) is formed by further continuing etching of oxygen gas, or a portion etched on the substrate surface by another gas (fluorine-based gas, chlorine-based gas) and a portion not etched. The
In some cases, the formed irregularities are further etched to form an etching layer toward the lower side of the substrate.
Drying and curing can be performed simultaneously, or curing can be performed after drying.
上記有機樹脂層(A)は酸素エッチングを行う上でマスクの機能を果たす。基板上に無機粒子を含まない有機樹脂層(B)を形成し、その上に無機粒子を含む有機樹脂層(A)を形成して、酸素ガスでエッチングすることにより、マスクとしての(A)層と(B)層の膜厚が厚くなり、その後の酸素系ガス又はその他のガスエッチング(例えばフッ素系ガス)によりエッチング差を生じやすくなるため高いアスペクト比を有する基板の粗化が可能になる。
また、ガスエッチングに変えて酸性水溶液を用いる湿式エッチングによっても上記と同様に粗化が可能になる。
The organic resin layer (A) functions as a mask in performing oxygen etching. An organic resin layer (B) containing no inorganic particles is formed on a substrate, an organic resin layer (A) containing inorganic particles is formed thereon, and etching is performed with oxygen gas, whereby (A) as a mask Layers (B) and (B) become thicker, and subsequent oxygen etching or other gas etching (for example, fluorine-based gas) tends to cause an etching difference, so that a substrate having a high aspect ratio can be roughened. .
In addition, roughening is possible in the same manner as described above by wet etching using an acidic aqueous solution instead of gas etching.
上記粗化とは基板表面をエッチングにより荒らすものであり、基板表面に化学的や物理的な変化を生じさせる。その一例として基板表面に凹凸が形成される。 The above roughening means that the surface of the substrate is roughened by etching, and a chemical or physical change is caused on the surface of the substrate. As an example, irregularities are formed on the substrate surface.
基板の粗化は無機粒子の平均粒子径や、有機樹脂層(A)に含まれる無機粒子の濃度(割合)によって変化し、必要とする基板上の粗化形状(凹凸形状)により決定される。 The roughening of the substrate varies depending on the average particle diameter of the inorganic particles and the concentration (ratio) of the inorganic particles contained in the organic resin layer (A), and is determined by the required roughening shape (uneven shape) on the substrate. .
本発明ではエッチングが少なくとも1回なされ、そのうち少なくとも1回のエッチングは酸素系ガスによるガスエッチングで行われる。酸素系ガスはガス成分として酸素を含むエッチングガスであり、酸素によって有機樹脂層(A)やその下層に存在する有機樹脂層(B)中の有機樹脂(a2)や有機樹脂(b2)が垂直方向にエッチングされ、また有機樹脂層(A)中の無機粒子(a1)は酸素ガスに対してエッチング抵抗を示す。そして、有機樹脂層(A)や有機樹脂層(B)のエッチングが基板面に到達した段階で、引き続き酸素系ガスでエッチングを行う場合や、その他のガス(例えば、フッ素成分を含むガス)によって基板をエッチングすることができる。 In the present invention, etching is performed at least once, and at least one of the etching is performed by gas etching using an oxygen-based gas. The oxygen-based gas is an etching gas containing oxygen as a gas component, and the organic resin (a2) and the organic resin (b2) in the organic resin layer (A) and the organic resin layer (B) existing below the oxygen resin are vertical due to oxygen. Etching is performed in the direction, and the inorganic particles (a1) in the organic resin layer (A) exhibit etching resistance against oxygen gas. When the etching of the organic resin layer (A) or the organic resin layer (B) reaches the substrate surface, the etching is continued with an oxygen-based gas, or other gases (for example, a gas containing a fluorine component). The substrate can be etched.
また、本発明ではエッチングが酸性水溶液による湿式エッチングで行うことができる。酸性水溶液により有機樹脂層(A)やその下層に存在する有機樹脂層(B)中の有機樹脂(a2)や有機樹脂(b2)が垂直方向にエッチングされ、また有機樹脂層(A)中の無機粒子(a1)は酸性水溶液に対してエッチング抵抗を示す。そして、有機樹脂層(A)や有機樹脂層(B)のエッチングが基板面に到達した段階で、引き続き酸性水溶液で基板をエッチングすることができる。 In the present invention, the etching can be performed by wet etching using an acidic aqueous solution. The organic resin (a2) and the organic resin (b2) in the organic resin layer (A) and the organic resin layer (B) existing below the organic resin layer (A) are etched in the vertical direction by the acidic aqueous solution, and the organic resin layer (A) The inorganic particles (a1) exhibit etching resistance against acidic aqueous solutions. Then, when the etching of the organic resin layer (A) or the organic resin layer (B) reaches the substrate surface, the substrate can be continuously etched with an acidic aqueous solution.
湿式エッチングに用いられる酸性水溶液は、酸と水を含んでいて、必要により過酸化水素や水溶性有機溶剤を含有することができる。酸は硫酸、硝酸、塩酸が用いられる。水溶性有機溶剤はアルコール系やエーテル系やケトン系やエステル系である。例えば、エチレングリコールモノメチルエーテル、エチレングリコールモノエチルエーテル、メチルセロソルブアセテート、エチルセロソルブアセテート、プロピレングリコールモノブチルエーテル、プロピレングリコールモノブチルエーテルアセテート、ジエチレングリコールモノメチルエーテル、ジエチレングリコールモノエチルエーテル、プロピレングリコール、プロピレングリコールモノメチルエーテル、プロピレングリコールモノメチルエーテルアセテート、プロピレングリコールモノエチルエーテル、プロピレングリコールモノエチルエーテルアセテート、プロピレングリコールモノプロピルエーテルアセテート、トルエン、キシレン、メチルエチルケトン、シクロペンタノン、シクロヘキサノン、2-ヒドロキシプロピオン酸エチル、2-ヒドロキシ-2-メチルプロピオン酸エチル、エトシキ酢酸エチル、ヒドロキシ酢酸エチル、2-ヒドロキシ-3-メチルブタン酸メチル、3-メトキシプロピオン酸メチル、3-メトキシプロピオン酸エチル、3-エトキシプロピオン酸メチル、3-エトキシプロピオン酸エチル、ピルビン酸メチル、ピルビン酸エチル、酢酸エチル、酢酸ブチル、乳酸エチル、乳酸ブチル等を用いることができる。これらの有機溶剤は単独で、または2種以上の組合せで使用される。
水と有機溶剤を合わせた全溶剤中での酸の濃度は0.01~97質量%であり、全溶剤中での過酸化水素の濃度は0.01~40質量%である。

本発明により、基板の表面を粗化する新規な方法が提供される。特に、本発明の方法は、基板上に無機物と有機物が混在する層を利用することができるので、無機物と有機物の酸素ガス又は酸性水溶液のエッチング速度差を利用して基板の表面に酸素ガス又は酸性水溶液によりエッチングされる部分とエッチングされない表面粗化層とを形成することができ、そして更にその表面粗化層をマスクとして酸素ガス又はフッ素系ガス等のガスや、酸性水溶液のエッチングにより基板表面を粗化、例えば基板上に微細な凹凸を形成することができる。また、これらの性質を利用してLED等の光取り出し層に適用することができる。 The present invention provides a novel method for roughening the surface of a substrate. In particular, since the method of the present invention can use a layer in which an inorganic substance and an organic substance are mixed on the substrate, the oxygen gas or the oxygen gas or A portion etched with an acidic aqueous solution and a surface roughened layer that is not etched can be formed. Further, using the surface roughened layer as a mask, a gas such as oxygen gas or fluorine-based gas or an acidic aqueous solution is used to etch the substrate surface. For example, fine irregularities can be formed on the substrate. Moreover, it can apply to light extraction layers, such as LED, using these characteristics.
