Description

本発明は、樹脂膜保持基板の製造方法、それによって得られる基板を用いる電子機器用回路基板の製造方法及びそれにより得られる該回路基板を備えた表示装置に関する。   The present invention relates to a method for manufacturing a resin film holding substrate, a method for manufacturing a circuit board for an electronic device using the substrate obtained thereby, and a display device including the circuit substrate obtained thereby.

電子機器用回路基板(以下、「回路基板」と記すことがある。)は、ガラスや合成樹脂などの基板又は少なくとも表面に絶縁体層が形成された基板に多数の薄膜トランジスタ、及び、これらのトランジスタの相互間若しくはトランジスタと電源や入出力端子とを接続するための電気配線層を単層又は多層に配置して構成されている。代表的な回路基板の用途の一つにアクティブマトリクス液晶表示装置や有機エレクトロルミネッセンス(以下「有機EL」と表記す。)表示装置などの表示装置がある。走査線、信号線などを含む基板全体はアクティブマトリクス基板とも呼ばれ、回路基板の表面に減圧雰囲気で形成される絶縁層やフォトリソグラフィなどによって形成される複数の回路パターン層により構成されている。しかしながら、上記アクティブマトリクス基板の製造方法は煩雑なため、減圧雰囲気における成膜工程やフォトリソグラフィ工程の削減によって簡素化を図ることが求められている。
特に、配線をスパッタにより成膜する工程では、全面に成膜した配線材料をフォトリソグラフィ法により加工して配線部を形成するため、膜厚を均一にすることを目的として基板面積より大きなターゲットにスパッタしたり、材料の大部分をエッチングで除去したりする。そのため、配線材料の利用効率が著しく低く、回路基板の製造工程を複雑にし、多量の廃棄物を出す要因になっている。
A circuit board for electronic equipment (hereinafter sometimes referred to as “circuit board”) includes a glass substrate, a synthetic resin substrate or the like, or a substrate having an insulator layer formed on at least a surface thereof, and a number of these thin film transistors. The electrical wiring layers for connecting the transistors to each other or the power source and the input / output terminal are arranged in a single layer or multiple layers. One of the typical uses of a circuit board is a display device such as an active matrix liquid crystal display device or an organic electroluminescence (hereinafter referred to as “organic EL”) display device. The entire substrate including the scanning lines and signal lines is also called an active matrix substrate, and is composed of an insulating layer formed in a reduced-pressure atmosphere on the surface of the circuit substrate and a plurality of circuit pattern layers formed by photolithography or the like. However, since the manufacturing method of the active matrix substrate is complicated, there is a demand for simplification by reducing the number of film forming steps and photolithography steps in a reduced pressure atmosphere.
In particular, in the process of forming the wiring by sputtering, the wiring material formed on the entire surface is processed by the photolithography method to form the wiring portion, so that the target is larger than the substrate area for the purpose of making the film thickness uniform. Sputtering or removing most of the material by etching. For this reason, the utilization efficiency of the wiring material is remarkably low, which complicates the circuit board manufacturing process and causes a large amount of waste.

このような問題を解決するために、印刷法により必要な部位のみに配線を形成し配線材料の利用効率を高める手法が開発されている。例えば、特許文献1にはインクジェット法を用いて所定の場所に配線を形成する方法が開示されている。このような印刷法を用いることで、減圧成膜工程を削減することができる。
ところで、インクジェット法を用いて基板上に配線を形成する場合、通常、配線を形成しようとする基板の上で、樹脂膜からなる凸状の仕切部材(「凸部」又は「バンク」とも呼ばれる。)で囲まれた領域(以下、「凹部」と記すことがある。)に液状の導電性材料を充填する方法が採られる。このとき、仕切部材が導電性材料に対して親液性を有する場合は、仕切部材に引っ張られて仕切部材の外周にまで濡れ広がり、所望の微細な配線幅を得ることができなくなる。一方、凹部の底面全体に液状の導電性材料が均一に濡れ拡がるためには、凹部底面(基板表面)は導電性材料に対して高い濡れ性を有する必要がある。底面が導電性材料に対する濡れ性に劣ると凹部に導電性材料が濡れ拡がらず、断線の原因になりかねない。
この濡れ性の問題に対して、特許文献2〜4は仕切部材の上部を撥液性にし、それ以外の部分を親液性にする表面処理技術を提案している。これらにおける仕切部材上部の撥液化表面処理技術は、減圧雰囲気下や大気圧雰囲気下でフッ素化合物を含むガスのプラズマを照射するなどの技術である。また、凹部底面の親液化の表面処理技術は、親水性基含有界面活性剤を塗布する方法や紫外線照射する方法などである。
In order to solve such a problem, a technique has been developed in which wiring is formed only in a necessary portion by a printing method to increase the utilization efficiency of the wiring material. For example, Patent Document 1 discloses a method of forming a wiring at a predetermined location using an inkjet method. By using such a printing method, the reduced pressure film forming step can be reduced.
By the way, when a wiring is formed on a substrate using an ink jet method, it is usually called a convex partition member (“convex portion” or “bank”) made of a resin film on the substrate on which the wiring is to be formed. ) (Hereinafter, referred to as “concave portion”) is filled with a liquid conductive material. At this time, when the partition member is lyophilic with respect to the conductive material, the partition member is pulled by the partition member and spreads to the outer periphery of the partition member, and a desired fine wiring width cannot be obtained. On the other hand, in order for the liquid conductive material to uniformly spread on the entire bottom surface of the recess, the bottom surface of the recess (substrate surface) needs to have high wettability with respect to the conductive material. If the bottom surface is inferior in wettability with respect to the conductive material, the conductive material does not spread out in the recess, which may cause disconnection.
In response to this wettability problem, Patent Documents 2 to 4 propose surface treatment techniques in which the upper part of the partition member is made liquid-repellent and the other parts are made lyophilic. The lyophobic surface treatment technology for the upper part of the partition member is a technology such as irradiating plasma of a gas containing a fluorine compound under a reduced pressure atmosphere or an atmospheric pressure atmosphere. The surface treatment technology for making the bottom surface of the recess lyophilic includes a method of applying a hydrophilic group-containing surfactant and a method of irradiating with ultraviolet rays.

しかし、幅10μm以下の微細幅配線をインクジェット法にて形成する場合は、基板面での液状の導電性材料に対する親液性(濡れ性)の差がより大きいことが必要であるが、未だ十分な差を実現できないためしばしば導電性材料の溢れや余分な濡れ拡がりが生じる。いまだ親液、撥液の大きな差が得られていないのは次の事情による。例えば、フッ素化合物を含むガスのプラズマ照射によって撥液部を形成する場合、仕切部材が有機材料であると、フッ化物形成と同時にフッ化物のエッチングも進行するので一定の撥液性しか得られない。また、一般的に界面活性剤溶液の塗布や紫外線照射により親液部を形成した後にフッ素化合物をプラズマ照射して撥液部を形成する手順を採るが、本来親液化されるべき部位も一部フッ化物が形成されてしまい、親液性のコントラストを拡大する効果が小さくなるという問題がある。さらに、プラズマ処理は垂直方向から行うため、フッ素化されるのは仕切部材の上面のみであり、仕切部材の側壁部は撥液性が低いままとなる。これらの事情により、微細配線形成の際は、液状の導電性材料の、基板上にある凹部底面での収納性が悪いのである。また、プラズマ装置が非常に高価なため、プラズマを多用する回路基板の製造方法は製造コストを押し上げるという問題もある。   However, when a fine width wiring having a width of 10 μm or less is formed by the inkjet method, it is necessary that the difference in lyophilicity (wetting property) with respect to the liquid conductive material on the substrate surface is larger, but it is still sufficient. Often this difference cannot be realized, resulting in overflow of the conductive material and excessive wetting and spreading. The large difference between the lyophilic and lyophobic properties has not been obtained due to the following circumstances. For example, when the liquid repellent part is formed by plasma irradiation of a gas containing a fluorine compound, if the partition member is made of an organic material, only a certain liquid repellent property can be obtained because the fluoride etching proceeds simultaneously with the fluoride formation. . In general, a procedure is adopted in which a lyophilic part is formed by applying a surfactant solution or by irradiating ultraviolet rays, and then irradiating the fluorine compound with plasma to form a lyophobic part. There is a problem that fluoride is formed and the effect of increasing the lyophilic contrast is reduced. Further, since the plasma treatment is performed from the vertical direction, only the upper surface of the partition member is fluorinated, and the side wall portion of the partition member remains low in liquid repellency. Due to these circumstances, when fine wiring is formed, the storage property of the liquid conductive material on the bottom surface of the recess on the substrate is poor. In addition, since the plasma apparatus is very expensive, there is a problem that the manufacturing method of the circuit board that frequently uses plasma increases the manufacturing cost.

撥液化の別法として、仕切部材用の有機材料をフッ素ガス雰囲気に曝してフッ化物を形成させる技術が以前より知られている。例えば特許文献5は、感光性樹脂をフッ素ガス雰囲気中に曝してフッ素樹脂膜を形成させる技術を提案している。これは、フッ素ガス雰囲気に曝すことにより樹脂中のC−H結合をC−F結合に変換し、炭素−炭素不飽和結合にフッ素を付加してフッ素樹脂を得るものである。しかし特許文献5の方法を実施するとフッ酸を生成することがあり、生成したフッ酸によって、有機材料からなる仕切部材である樹脂膜やシリコン系の基板が劣化することがある。   As another method of liquid repellency, a technique for forming a fluoride by exposing an organic material for a partition member to a fluorine gas atmosphere has been known. For example, Patent Document 5 proposes a technique for forming a fluororesin film by exposing a photosensitive resin to a fluorine gas atmosphere. In this method, the C—H bond in the resin is converted to a C—F bond by exposure to a fluorine gas atmosphere, and fluorine is added to the carbon-carbon unsaturated bond to obtain a fluororesin. However, when the method of Patent Document 5 is performed, hydrofluoric acid may be generated, and the generated hydrofluoric acid may cause deterioration of a resin film or a silicon-based substrate that is a partition member made of an organic material.

(4a) Oxygen Plasma or Ultraviolet Irradiation Treatment Step FIG. 1E shows a step of performing oxygen plasma treatment or ultraviolet irradiation treatment on the substrate surface. Although this step is not essential for the method of manufacturing the resin film holding substrate of the present invention, the contrast of the wettability with respect to the liquid conductive material between the upper surface of the resin film and the substrate surface can be expanded. It is preferable to install as a pre-process of the fluorine gas treatment process of the light shielding part 22. This step is also effective for removing the resin residue remaining on the substrate surface when the pattern is formed on the thermosetting resin film by the exposure and development or etching. If the fluorine gas treatment described below is performed with the resin residue remaining on the exposed portion of the substrate, a fluorine compound may be formed on the surface of the resin residue, which may reduce the difference in wettability between the surface of the thermosetting resin and the opening portion. is there.

(5)樹脂膜乾燥後フッ素ガス雰囲気に曝す工程(フッ素化工程)
図2(f)は、乾燥を経た樹脂膜保持基板をフッ素ガス雰囲気に曝す工程を示す。樹脂膜保持基板の乾燥条件は、通常50〜300℃、好ましくは150〜250℃の温度で、通常10〜200分間、好ましくは30〜150分間置く。乾燥によって、樹脂膜の水分含有量を好ましくは1重量%以下、より好ましくは0.1重量%以下、特に好ましくは0.05重量%以下にする。水分含有量が多いと、フッ素ガスと水分が反応してフッ化水素が生じ、樹脂の表面処理を妨げるとともに、樹脂膜の変質や基板からの剥離などの不具合を生ずるおそれがある。
(5) Step of exposing to fluorine gas atmosphere after resin film drying (fluorination step)
FIG. 2F shows a process of exposing the dried resin film holding substrate to a fluorine gas atmosphere. The drying condition of the resin film holding substrate is usually 50 to 300 ° C., preferably 150 to 250 ° C., usually 10 to 200 minutes, preferably 30 to 150 minutes. By drying, the moisture content of the resin film is preferably 1% by weight or less, more preferably 0.1% by weight or less, and particularly preferably 0.05% by weight or less. When the moisture content is high, fluorine gas reacts with moisture to produce hydrogen fluoride, which hinders the surface treatment of the resin and may cause problems such as deterioration of the resin film and peeling from the substrate.

フッ素ガス雰囲気のフッ素ガスは、希ガス類や窒素などの不活性ガスで希釈して使用することが好ましい。フッ素ガス濃度は特に限定されないが、好ましくは0.1〜50容量%、より好ましくは0.3〜30容量%、特に好ましくは0.5〜20容量%である。フッ素ガス濃度が低すぎると、樹脂膜表面のフッ化物の生成が不十分になるおそれがある。一方、濃度が高すぎると、フッ素と樹脂膜との反応が急激すぎて好ましくない事態を生ずる可能性がある。また、樹脂膜保持基板をフッ素ガス雰囲気に曝す方法に特に限定はない。例えば、樹脂膜保持基板を容器中に置いてフッ素ガスを常圧で流通させる、又は、密封下でフッ素ガスを加圧状態で充満させるなどの方法が挙げられる。   The fluorine gas in the fluorine gas atmosphere is preferably diluted with an inert gas such as a rare gas or nitrogen. The fluorine gas concentration is not particularly limited, but is preferably 0.1 to 50% by volume, more preferably 0.3 to 30% by volume, and particularly preferably 0.5 to 20% by volume. If the fluorine gas concentration is too low, the generation of fluoride on the surface of the resin film may be insufficient. On the other hand, if the concentration is too high, the reaction between fluorine and the resin film is too rapid, which may cause an undesirable situation. There is no particular limitation on the method of exposing the resin film holding substrate to the fluorine gas atmosphere. For example, the resin film holding substrate is placed in a container and fluorine gas is allowed to flow at normal pressure, or fluorine gas is filled in a pressurized state under sealing.

フッ素ガス雰囲気の水分含有量は、少ない方が樹脂膜の表面処理に有効である。フッ素ガス雰囲気の水分含有量は、好ましくは100ppm以下、より好ましくは10ppm以下、特に好ましくは1ppm以下である。水分濃度が上記範囲であると、フッ化水素が生成しにくくなる。
フッ素化工程における樹脂膜保持基板の温度は、通常23〜300℃、好ましくは50〜250℃である。
A smaller moisture content in the fluorine gas atmosphere is more effective for the surface treatment of the resin film. The moisture content in the fluorine gas atmosphere is preferably 100 ppm or less, more preferably 10 ppm or less, and particularly preferably 1 ppm or less. When the moisture concentration is in the above range, hydrogen fluoride is hardly generated.

(5a) Heating process (annealing process)
FIG. 2G shows a step of heating (annealing) the resin film holding substrate in an inert gas in order to enhance the liquid repellency of the resin surface after exposure to a fluorine gas atmosphere. Although this step is not essential for the method for producing the resin film holding substrate of the present invention, annealing has the effect of promoting the fluorination of the portion where the fluorination is insufficient and volatilizing excess fluorine. It is preferable to be performed subsequent to the conversion step. The type of inert gas used for annealing is not particularly limited, and examples thereof include rare gases such as helium, neon, argon, krypton, xenon, and radon, and nitrogen. The annealing temperature varies depending on the softening point of the cured resin used, but is preferably 50 to 350 ° C, more preferably 200 to 300 ° C. When the annealing temperature is within the above range, the above-mentioned effects of annealing are sufficiently exhibited, and the generated fluoride is not likely to volatilize.

The half surface of the alkali-free glass substrate on which the resin film is formed is shielded with a mask, exposed at 200 mJ / cm 2 with a mask aligner, and then developed in an aqueous 2.38% tetramethylammonium hydroxide (TMAH) solution at 25 ° C. for 70 seconds. Then, a rinse treatment was performed with ultrapure water for 30 seconds. Thereby, since the said radiation sensitive resin composition was a positive type, the resin exposure part melt | dissolved and the resin film of the glass substrate upper half surface was removed.

表1が示すように、表面がフッ素ガス雰囲気に曝されたパターン状に硬化した樹脂膜の上面のテトラデカン接触角は62度で極めて低い濡れ性を示し、また、該樹脂膜を載置した絶縁基板をTMAH水溶液に接触させることによりガラス面のテトラデカン接触角は9度で極めて高い濡れ性を呈した。これにより両接触角の較差は53度と大きな濡れ性のコントラストを実現した(実施例1)。
これに対して、樹脂膜を載置した絶縁基板に対するTMAH水溶液接触処理のみを省略すると、ガラス面の濡れ性が改善されないため、テトラデカン接触角の較差は49度に縮小した(比較例2)。TMAH水溶液接触処理に代えて酸素プラズマ処理を行うと、樹脂表面の濡れ性も向上するためテトラデカン接触角の較差は31度に縮まった(比較例3)。TMAH水溶液接触処理に代えてフッ素系界面活性剤を用いてガラス面上に親液皮膜形成を行っても、親液化の効果は小さく、テトラデカン接触角の較差は27度に縮小した(比較例4)。
また、樹脂膜に対するフッ素化処理、及び、樹脂膜を載置した絶縁基板に対するTMAH水溶液接触処理を、共に実施しないとテトラデカン接触角の較差は1度と、樹脂面及び基板面の濡れ性がほとんど同等となった(比較例1)。
As shown in Table 1, the tetradecane contact angle on the top surface of the resin film cured in a pattern exposed to a fluorine gas atmosphere is 62 degrees, indicating extremely low wettability, and the insulation on which the resin film is placed By bringing the substrate into contact with the TMAH aqueous solution, the contact angle of tetradecane on the glass surface was 9 degrees, and extremely wettability was exhibited. As a result, the difference between both contact angles was 53 degrees, and a high wettability contrast was achieved (Example 1).
On the other hand, if only the TMAH aqueous solution contact treatment with respect to the insulating substrate on which the resin film was placed was omitted, the wettability of the glass surface was not improved, and the difference in the tetradecane contact angle was reduced to 49 degrees (Comparative Example 2). When the oxygen plasma treatment was performed instead of the TMAH aqueous solution contact treatment, the wettability of the resin surface was improved, and the difference in the tetradecane contact angle was reduced to 31 degrees (Comparative Example 3). Even when a lyophilic film was formed on the glass surface using a fluorosurfactant instead of the TMAH aqueous solution contact treatment, the effect of lyophilicity was small, and the difference in the tetradecane contact angle was reduced to 27 degrees (Comparative Example 4). ).
Moreover, if the fluorination treatment for the resin film and the TMAH aqueous solution contact treatment for the insulating substrate on which the resin film is placed are not performed together, the difference in tetradecane contact angle is 1 degree, and the wettability of the resin surface and the substrate surface is almost the same. It became equivalent (comparative example 1).

一方、樹脂膜に対するフッ素ガスによるフッ素化処理も、樹脂膜を載置した基板に対するTMAH水溶液接触処理も、共に実施しないと、幅が50μmの溝でも導電性材料が全面的にはみ出し、微細な配線は不可能であった(比較例5)。また、樹脂膜の表面を、フッ素ガスに曝す代わりに四フッ化炭素プラズマによる撥液処理を行い、その後樹脂膜保持基板をTMAH水溶液に接触させる親液処理を行っても、導電性材料の収納限界幅は30μmで微細部位収納性は不十分であった(比較例6)。
As shown in Table 2, the resin film holding substrate having a partition member made of a resin film having a surface exposed to a fluorine gas atmosphere and a groove bottom made of a glass surface in contact with the TMAH aqueous solution has a width of 10 μm. It was shown that the conductive material did not protrude even in the groove, and fine wiring was possible (Example 2).

Even if the surface of the resin film is subjected to lyophobic treatment with carbon tetrafluoride plasma instead of being exposed to fluorine gas, and then subjected to lyophilic treatment in which the resin film holding substrate is brought into contact with the TMAH aqueous solution, the conductive material can be stored. The limit width was 30 μm, and the fine area storage was insufficient (Comparative Example 6).

Next, by selectively exposing, developing, and heat-curing the resin film using actinic radiation, a resin in which a transparent resin film having a wiring groove is placed on the glass substrate shown in FIG. A film holding substrate was obtained. This resin film holding substrate was subjected to oxygen plasma treatment at 2.67 Pa for 10 seconds with an RF plasma apparatus, then exposed to a fluorine gas atmosphere to treat the surface with fluorine, and then immersed in a 2.38% TMAH aqueous solution at 23 ° C. for 10 seconds. did.

次にインクジェット印刷法により、前記溝部に導電性材料を充填した。本実施例では導電性材料として、市販されている超微粒子の銀の分散液(パーフェクトシルバー、真空冶金社製;平均粒径8nmの銀微粒子100部、ドデシルアミン15部、ターピネオール75部)の銀100部に対し、メチルヘキサヒドロ無水フタル酸6.8部、レゾール型フェノール樹脂(PL−2211、群栄化学社製)5部、トルエン35部を混合後0.5μmのフィルタでろ過して調製した銀ペーストインクを用いて配線を形成した。導電性材料を充填後250度の温度で30分間焼成し、走査線及びゲート電極配線とした〔図6(b)〕。次に、マイクロ波励起プラズマを用いたプラズマCVD法によりSiHガス、Hガス、Nガス及びArガスを用いてシリコン窒化膜(SiN膜)を形成した。 Next, the groove material was filled with a conductive material by an ink jet printing method. In this example, as a conductive material, a commercially available silver dispersion of ultrafine particles (Perfect Silver, manufactured by Vacuum Metallurgical Company; 100 parts of silver fine particles with an average particle diameter of 8 nm, 15 parts of dodecylamine, 75 parts of terpineol) Prepared by mixing 6.8 parts of methylhexahydrophthalic anhydride, 5 parts of resol type phenolic resin (PL-2211, Gunei Chemical Co., Ltd.) and 35 parts of toluene with 100 parts, followed by filtration with a 0.5 μm filter. Wiring was formed using the prepared silver paste ink. After filling with the conductive material, it was baked for 30 minutes at a temperature of 250 ° C. to form scanning lines and gate electrode wirings (FIG. 6B). Next, a silicon nitride film (SiN x film) was formed using SiH 4 gas, H 2 gas, N 2 gas, and Ar gas by plasma CVD using microwave excitation plasma.

次に、マイクロ波励起プラズマを用いたプラズマCVD法により300℃にて、SiHガスを通気してアモルファスシリコン層を、次いで、SiHガス、PHガス及びArガスを通気してn+型アモルファスシリコン層を順次成膜した〔図6(c)〕。次に、全面にフォトレジストをスピンコート法により塗布し、100℃で1分間、ホットプレート上で乾燥し溶剤を除去した。次にg線ステッパを用いて、36mJ/cmのエネルギー量で露光した。露光に際しては、素子領域を残存するようにマスクを形成し、素子領域内部のチャネル領域に相当する部分はスリットマスクを用いて、露光量を調整した。2.38%TMAH水溶液を用いてパドル現像70秒間を行った結果、図6(d)に示すフォトレジスト形状を有するサンプルを得た。 Next, at 300 ° C. by plasma CVD using microwave excitation plasma, SiH 4 gas is vented to pass through the amorphous silicon layer, then SiH 4 gas, PH 3 gas and Ar gas are vented to form n + type amorphous. Silicon layers were sequentially formed [FIG. 6 (c)]. Next, a photoresist was applied to the entire surface by spin coating, and dried on a hot plate at 100 ° C. for 1 minute to remove the solvent. Next, it exposed with the energy amount of 36 mJ / cm < 2 > using the g line | wire stepper. At the time of exposure, a mask was formed so as to leave the element region, and the exposure amount was adjusted by using a slit mask for a portion corresponding to the channel region inside the element region. As a result of performing paddle development for 70 seconds using a 2.38% TMAH aqueous solution, a sample having the photoresist shape shown in FIG. 6D was obtained.

次に、プラズマエッチング装置を用いて、n+型アモルファスシリコン層及びアモルファスシリコン層のエッチングを行った。この際、フォトレジストも若干エッチングされ、膜厚が減少するため、フォトレジスト膜厚の薄いチャネル領域部のレジストはエッチング除去され、n+シリコン層もエッチングされた。素子領域部以外のn+型アモルファスシリコン層及びアモルファスシリコン層がエッチング除去され、チャネル領域のn+型アモルファスシリコン層がエッチング除去された時点で、エッチング処理を終了し、図6(e)に示す形状を有するサンプルを得た。ソース電極部及びドレイン電極部のn+型アモルファスシリコン層上のフォトレジストは残存したままの状態で、Arガス、Nガス、Hガスを用いて、マイクロ波励起プラズマ処理を行い、チャネル部のアモルファスシリコン表面に直接、窒化膜を形成した〔図7(f)〕。 Next, the n + type amorphous silicon layer and the amorphous silicon layer were etched using a plasma etching apparatus. At this time, the photoresist was also slightly etched to reduce the film thickness, so that the resist in the channel region where the photoresist film thickness was thin was removed by etching, and the n + silicon layer was also etched. When the n + type amorphous silicon layer and the amorphous silicon layer other than the element region are removed by etching and the n + type amorphous silicon layer in the channel region is removed by etching, the etching process is finished, and the shape shown in FIG.

前記サンプルを酸素プラズマ処理後、フッ素ガス雰囲気に曝して表面をフッ素処理し、次いで2.38%TMAH水溶液に浸漬した。次にインクジェット印刷法により、溝部に前記銀ペーストインクの導電性材料を充填した。導電性材料を充填後250度の温度で30分間焼成し、配線とした〔図6(i)〕。このようにして、TFTの形成を完了した。   After the oxygen plasma treatment, the sample was exposed to a fluorine gas atmosphere to treat the surface with fluorine, and then immersed in a 2.38% TMAH aqueous solution. Next, the conductive material of the silver paste ink was filled in the groove by an ink jet printing method. After filling the conductive material, it was baked at a temperature of 250 ° C. for 30 minutes to form a wiring [FIG. 6 (i)]. In this way, the formation of the TFT was completed.

次に、層間絶縁膜として、カルボキシル基含有脂環式オレフィン系樹脂による感光性で透明の樹脂膜を形成し、露光、現像を行って画素電極からTFT電極へのコンタクトホールを形成した。感光性透明樹脂の硬化は、感光性透明樹脂の光線透過率を高めるため、装置内表面をSUS316の電解研磨処理した加熱装置を用い、また、残存酸素濃度を10ppmに制御し、250℃で60分焼成した。これに引き続き、基板全面にITOをスパッタ成膜し、パターニングすることで画素電極とした。この表面に液晶の配向膜としてポリイミド膜を形成し、対向基板との間に液晶を挟持することにより図5に示す構造を有するアクティブマトリクス液晶表示装置を得た。
同表示装置は、平坦化層の透明性が高いため、輝度が高く、かつ、消費電力が低かった。
Next, as the interlayer insulating film, a photosensitive and transparent resin film was formed from a carboxyl group-containing alicyclic olefin-based resin, and exposure and development were performed to form a contact hole from the pixel electrode to the TFT electrode. In order to increase the light transmittance of the photosensitive transparent resin, the photosensitive transparent resin is cured by using a heating device in which the inner surface of the device is electropolished with SUS316, and the residual oxygen concentration is controlled to 10 ppm. Bake for minutes. Subsequently, ITO was sputtered on the entire surface of the substrate and patterned to form a pixel electrode. A polyimide film was formed on the surface as a liquid crystal alignment film, and the liquid crystal was sandwiched between the opposite substrate and an active matrix liquid crystal display device having the structure shown in FIG. 5 was obtained.
Since the flattening layer has high transparency, the display device has high luminance and low power consumption.
