上記バインダー樹脂は導電性金属材料又は絶縁材料を固定する働きを有する。従来、塗工性に優れ、精密な形状の塗膜を容易に形成することができるという理由から、エチルセルロース樹脂が主に用いられてきた。しかし、エチルセルロース樹脂は熱分解性が低いため焼成後にカーボン成分が灰分として残留し、それにより電気特性が低下したり、熱分解する過程で揮発分となり空隙(ボイド)を発生させ、配線・塗膜形成の不良や層間剥離(デラミネーション)等により歩留まりを低下させたりすることが問題であった。
The binder resin has a function of fixing the conductive metal material or the insulating material. Conventionally, ethyl cellulose resin has been mainly used because it has excellent coatability and can easily form a coating film with a precise shape. However, since ethylcellulose resin has low thermal decomposability, the carbon component remains as ash after firing, which reduces electrical properties and causes volatiles to form voids in the process of thermal decomposition, resulting in wiring and coating films. It has been a problem to reduce the yield due to poor formation or delamination.
従来は各層の膜厚が厚かったためにこれらの問題はそれほど大きくなかったが、近年、電子デバイスの高性能化、小型化に伴い、装置を構成する配線、塗膜、セラミック層の薄層化が求められる結果、このような問題が顕著に認められるようになった。
Conventionally, these problems were not so great because the thickness of each layer was large, but in recent years, with the improvement in performance and miniaturization of electronic devices, the wiring, coating film, and ceramic layer constituting the device have become thinner. As a result, such a problem has been recognized remarkably.
そこで、電気特性の低下、配線・塗膜形成の不良、及びデラミネーションの発生を改善する方法として、ペースト組成物に含まれるバインダー樹脂の改善が種々検討された。例えば、特許文献1には、エチルセルロース樹脂に代えてポリビニルアセタール樹脂を用いることでグリーンシートとの密着性向上や灰分を低減することが開示されている。しかしながら、上記ポリビニルアセタール樹脂を使用しても導電性の低下、配線・塗膜形成の不良、及びデラミネーションの発生を完全に防ぐことは困難であった。
Therefore, various improvements of the binder resin contained in the paste composition have been studied as methods for improving the deterioration of electrical characteristics, the poor wiring / coating film formation, and the occurrence of delamination. For example, Patent Document 1 discloses that using a polyvinyl acetal resin instead of an ethyl cellulose resin improves adhesion with a green sheet and reduces ash content. However, even if the polyvinyl acetal resin is used, it has been difficult to completely prevent the decrease in conductivity, the poor wiring / coating film formation, and the occurrence of delamination.
従って、本発明の目的は、印刷法により被塗布面部材に塗布することにより電子デバイスの配線又は塗膜形成を行うペースト組成物の原料となる溶剤組成物であって、電気特性の低下、配線・塗膜形成の不良、及びデラミネーションの発生を抑制することができる溶剤組成物を提供することにある。
Accordingly, an object of the present invention is a solvent composition which is a raw material of a paste composition for performing wiring or coating film formation of an electronic device by being applied to a surface member to be coated by a printing method. -It is providing the solvent composition which can suppress the defect of coating-film formation and generation | occurrence | production of delamination.
本発明者等は上記課題を解決するため鋭意検討した結果、特定の構造を有する低分子のゲル化剤は、加熱溶融すると溶剤中において自己組織化によりひも状会合体を形成して高分子のような粘性を示すこと、エチルセルロース等の高分子化合物に比べ低温で揮発すること、熱分解性に優れ、焼成による灰分の残留や揮発分の発生を著しく低減することができることを見いだした。
As a result of intensive studies to solve the above problems, the present inventors have found that a low molecular gelling agent having a specific structure forms a string-like aggregate by self-organization in a solvent when heated and melted. It has been found that it exhibits such a viscosity, volatilizes at a low temperature as compared with a high molecular compound such as ethyl cellulose, is excellent in thermal decomposability, and can significantly reduce the residue of ash and the generation of volatile components by baking.
そして、印刷法による電子デバイス製造において、エチルセルロース等のバインダー樹脂を溶剤と混合して得られたペースト組成物に代えて前記低分子のゲル化剤と溶剤との混合物を加熱溶解して得られるペースト組成物を使用すると、塗布工程においては印刷法による配線・塗膜の形成に適した粘度を有し、液ダレしにくく高精度の配線パターンを形成することができること、乾燥工程及び焼成工程においては、長時間高温で加熱する必要が無く、低温で速やかに乾燥・焼成することができ、被塗布面部材が長時間高温に曝されることにより軟化、変形することを防止できること、焼成工程を経ても配線・塗膜中に灰分の残留や揮発分の発生を著しく低減することができ、これらにより引き起こされていた電気特性の低下、配線・塗膜形成の不良、及びデラミネーションの発生を抑制することができることを見いだした。本発明はこれらの知見に基づいて完成させたものである。
And in electronic device manufacturing by printing method, instead of paste composition obtained by mixing binder resin such as ethyl cellulose with solvent, paste obtained by heating and dissolving the mixture of low molecular weight gelling agent and solvent When the composition is used, the coating process has a viscosity suitable for the formation of wiring and coating films by the printing method, and is capable of forming a highly accurate wiring pattern that is difficult to drip, in the drying process and firing process. It is not necessary to heat at a high temperature for a long time, it can be quickly dried and fired at a low temperature, the coated surface member can be prevented from being softened and deformed by being exposed to a high temperature for a long time, and through a firing process. As a result, the generation of residual ash and volatile components in the wiring and coating film can be significantly reduced. It found that it is possible to suppress defects and the occurrence of delamination. The present invention has been completed based on these findings.

また、実施例で使用したゲル化剤、及び比較例で使用した高分子バインダー樹脂について、各20mgをTG-DTAにて20℃から400℃まで10℃/分で昇温して温度毎の減少重量を測定し、蒸発温度(重量が0.1%以下に減少した時点の温度)と350℃における残留灰分量を求めた(図1参照)。
その結果、実施例で使用したゲル化剤は何れも、比較例で使用した高分子バインダー樹脂より低温で気化した。さらに、比較例1で使用した高分子バインダー樹脂は350℃の加熱を行っても樹脂溶液全体の6.3重量%が灰分として残ったのに対し、実施例で使用したゲル化剤のほとんどは350℃まで昇温する前に完全に気化し、灰分を残さなかった。 In addition, for the gelling agent used in the examples and the polymer binder resin used in the comparative example, 20 mg each was increased from 20 ° C. to 400 ° C. at 10 ° C./min with TG-DTA, and decreased at each temperature. The weight was measured, and the evaporation temperature (the temperature when the weight decreased to 0.1% or less) and the residual ash content at 350 ° C. were determined (see FIG. 1).
As a result, all the gelling agents used in the examples were vaporized at a lower temperature than the polymer binder resin used in the comparative examples. Furthermore, the polymer binder resin used in Comparative Example 1 remained as ash in an amount of 6.3% by weight of the entire resin solution even when heated at 350 ° C., whereas most of the gelling agents used in the Examples were Before the temperature was raised to 350 ° C., it was completely vaporized, leaving no ash.

そして、前記ペースト組成物を使用すると、液ダレしにくく高精度の配線パターンを形成することができる。また、乾燥工程及び焼成工程において、低温で乾燥・焼成することができ、被塗布面部材が長時間高温に曝されることにより軟化、変形することを防止できる。更に、焼成工程を経ても配線・塗膜中に灰分の残留や揮発分の発生を著しく低減することができ、これらにより引き起こされていた電気特性の低下、配線・塗膜形成の不良、及びデラミネーションの発生を抑制することができ、配線・塗膜形成の不良やデラミネーション等による歩留まりの低下を解消し、電気特性に優れた配線、塗膜を形成することができる。
従って、本発明の電子デバイス製造用溶剤組成物は、各印刷法により電気デバイスの微細パターンを形成するペースト組成物の原料として極めて有用である。 The solvent composition for producing an electronic device of the present invention can form a paste composition having a viscosity suitable for formation of a wiring / coating film by a printing method by heating and dissolving.
And if the said paste composition is used, it will be hard to drip and a highly accurate wiring pattern can be formed. Moreover, in a drying process and a baking process, it can dry and bake at low temperature, and it can prevent softening and a deformation | transformation when a to-be-coated surface member is exposed to high temperature for a long time. Furthermore, the ash residue and volatile matter in the wiring / coating film can be significantly reduced even after the firing process, resulting in the deterioration of electrical characteristics, poor wiring / coating film formation, and degeneration. Generation of lamination can be suppressed, and a decrease in yield due to poor wiring / coating film formation or delamination can be eliminated, and wiring and coating films having excellent electrical characteristics can be formed.
Therefore, the solvent composition for producing an electronic device of the present invention is extremely useful as a raw material for a paste composition for forming a fine pattern of an electric device by each printing method.
