Abstract

<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a gas barrier film, or the like, wherein the gas barrier film has excellent adhesion between laminates even in the case of a laminate structure and has superior gas barrier property. <P>SOLUTION: The gas barrier film 1 is composed of a liquid crystal polymer resin film 2, a fluorinated resin film 3 having an adhesive functional group laminated and fused to the liquid crystal polymer resin film, and a fluorinated resin film 4 having no adhesive functional group laminated and fused to the fluorinated resin film. As a result, since the fluorinated resin film having the adhesive functional group is held between the liquid crystal polymer resin film and the fluorinated resin film having no adhesive functional group for the lamination and fusion, excellent inter-lamination adhesion is secured by the fluorinated resin film having the adhesive functional group. Further, while the liquid crystal polymer resin film is protected with the fluorinated resin film having no adhesive functional group, superior gas barrier property is secured with the liquid crystal polymer resin film. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、ガスバリア性を有するフィルムの製造方法、ガスバリアフィルム及び該フィルムで形成されたガスバリアバッグに関する。   The present invention relates to a method for producing a film having gas barrier properties, a gas barrier film, and a gas barrier bag formed from the film.

特許文献1には、半導体露光装置においてフォトレジスト溶液を送液するシステムとして低溶出性のポリテトラフルオロエチレン(以下、「PTFE」という)で成るパックにフォトレジスト溶液を入れ気体の圧力で送液するシステムが開示されている。しかし、PTFEは低溶出性、耐薬品性には優れるが気体透過性が大きく、すなわちガスバリア性が小さく気泡が混入し易いという欠点がある。フォトレジスト溶液に気泡が存在するとシリコンウエハ上に欠陥が生じ露光不良が発生する。特に近年、回路幅が狭小になってきていることから、僅かな気泡の存在も問題になってきている。   In Patent Document 1, as a system for feeding a photoresist solution in a semiconductor exposure apparatus, the photoresist solution is put in a pack made of polytetrafluoroethylene (hereinafter referred to as “PTFE”) having a low elution property and fed at a gas pressure. A system is disclosed. However, although PTFE is excellent in low elution property and chemical resistance, it has a disadvantage that gas permeability is large, that is, gas barrier property is small and bubbles are easily mixed. If bubbles exist in the photoresist solution, defects occur on the silicon wafer, resulting in poor exposure. In particular, since the circuit width has become narrow in recent years, the presence of slight bubbles has become a problem.

この問題を解消するものとして、特許文献2には、液晶ポリエステルを連続相とし液晶ポリエステルと反応性を有する官能基を有する共重合体を分散相とする液晶ポリエステル樹脂組成物よりなる層と、熱可塑性樹脂よりなる層とを有する積層構造の液体バッグが開示されている。この液体バッグによれば液晶ポリエステル樹脂組成物はガスバリア性に優れるためフォトレジスト溶液への気泡の混入を防止することができる。
特表2008−503399号公報 特開平11−60757号公報
In order to solve this problem, Patent Document 2 discloses a layer made of a liquid crystal polyester resin composition having a liquid crystal polyester as a continuous phase and a copolymer having a functional group having reactivity with the liquid crystal polyester as a dispersed phase, A laminated structure liquid bag having a layer made of a plastic resin is disclosed. According to this liquid bag, since the liquid crystal polyester resin composition is excellent in gas barrier properties, bubbles can be prevented from being mixed into the photoresist solution.
Special table 2008-503399 gazette Japanese Patent Laid-Open No. 11-60757

上述した液晶ポリエステル樹脂組成物よりなる層と熱可塑性樹脂よりなる層とを有する積層構造の液体バッグでは、液晶ポリエステル樹脂組成物よりなる層と熱可塑性樹脂よりなる層とが密着性に劣るため液体バッグの取り扱い中に剥離する場合がある。そして、液晶ポリエステル樹脂組成物よりなる層と熱可塑性樹脂よりなる層とが剥離してしまうと、液晶ポリエステル樹脂組成物よりなる層と熱可塑性樹脂よりなる層との間に気体が入り込み、液体バッグ内に収容されている液体を、例えば圧力を使用して送液しようとする場合に、送液量が不正確になったり、送液応答性が悪化するおそれがある。液晶ポリエステル樹脂組成物よりなる層と熱可塑性樹脂よりなる層との密着性を高めるためには接着剤を使用すればよいが、接着剤の成分がフォトレジスト溶液に溶出するおそれがある。また、一般の熱可塑性樹脂は、耐薬品性、低溶出性および耐熱性などに劣る。以上のように、PTFEのようなフッ素樹脂は、耐薬品性、低溶出性および耐熱性などに優れるものの、ガスバリア性に劣ると共に液晶ポリエステル樹脂組成物との密着性にも劣り、耐薬品性、低溶出性および耐熱性に優れ、かつ良好なガスバリア性を有する液体バッグの出現が望まれている。   In a liquid bag having a laminated structure having a layer made of the above-mentioned liquid crystal polyester resin composition and a layer made of a thermoplastic resin, the liquid bag made of a liquid crystal polyester resin composition and the layer made of a thermoplastic resin are inferior in adhesiveness, so that the liquid May peel during bag handling. When the layer made of the liquid crystal polyester resin composition and the layer made of the thermoplastic resin are peeled off, gas enters between the layer made of the liquid crystal polyester resin composition and the layer made of the thermoplastic resin, and the liquid bag For example, when the liquid contained in the liquid is to be fed using pressure, the liquid feeding amount may be inaccurate or the liquid feeding responsiveness may deteriorate. An adhesive may be used to increase the adhesion between the layer made of the liquid crystal polyester resin composition and the layer made of the thermoplastic resin, but the adhesive component may be eluted into the photoresist solution. Moreover, a general thermoplastic resin is inferior in chemical resistance, low elution property, heat resistance, etc. As described above, a fluororesin such as PTFE is excellent in chemical resistance, low elution property, heat resistance, and the like, but is inferior in gas barrier properties and adhesiveness with a liquid crystal polyester resin composition, and has chemical resistance, The appearance of a liquid bag having excellent low elution and heat resistance and good gas barrier properties is desired.

本発明は、上述した事情からなされたものであり、本発明の目的は、耐薬品性、低溶出性、耐熱性などに優れ、積層構造であっても積層間の密着性に優れかつガスバリア性に優れたガスバリアフィルムの製造方法、ガスバリアフィルム及び該フィルムで形成されたガスバリアバッグを提供することにある。   The present invention has been made from the above-described circumstances, and the object of the present invention is excellent in chemical resistance, low elution, heat resistance, etc., and has excellent adhesion between layers and gas barrier properties even in a laminated structure. An object of the present invention is to provide a method for producing a gas barrier film, a gas barrier film, and a gas barrier bag formed of the film.

上記目的達成のため、本発明のガスバリア性を有するフィルムの製造方法は、液晶ポリマ樹脂フィルムを表面処理し、該液晶ポリマ樹脂フィルムに接着性官能基を有するフッ素

In order to achieve the above object, the method for producing a film having gas barrier properties according to the present invention comprises surface-treating a liquid crystal polymer resin film and laminating and fusing a fluororesin film having an adhesive functional group on the liquid crystal polymer resin film, A fluororesin film having no adhesive functional group is laminated and fused to the fluororesin film. The film having gas barrier properties of the present invention was laminated and fused to a liquid crystal polymer resin film, a fluororesin film having an adhesive functional group laminated and fused to the liquid crystal polymer resin film, and the fluororesin film. And a fluororesin film having no adhesive functional group.

これにより、液晶ポリマ樹脂フィルムと接着性官能基を有しないフッ素樹脂フィルムとの間に、接着性官能基を有するフッ素樹脂フィルムを挟んで積層融着しているので、接着性官能基を有するフッ素樹脂フィルムにより各積層間において優れた密着性を確保することができる。さらに、接着性官能基を有しないフッ素樹脂フィルムにより液晶ポリマ樹脂フィルムを保護しつつ、この液晶ポリマ樹脂フィルムにより優れたガスバリア性を確保することができる。   As a result, the liquid crystal polymer resin film and the fluororesin film having no adhesive functional group are laminated and fused with the fluororesin film having the adhesive functional group interposed therebetween. The resin film can ensure excellent adhesion between the respective layers. Furthermore, while protecting a liquid crystal polymer resin film with the fluororesin film which does not have an adhesive functional group, the gas barrier property excellent in this liquid crystal polymer resin film can be ensured.

また、前記液晶ポリマ樹脂フィルムは、表面処理されていることを特徴としている。これにより、液晶ポリマ樹脂フィルムと接着性官能基を有するフッ素樹脂フィルムとの密着強度をさらに高めることができる。   Further, the liquid crystal polymer resin film is characterized by being surface-treated. Thereby, the adhesive strength of a liquid crystal polymer resin film and the fluororesin film which has an adhesive functional group can further be raised.

上記目的達成のため、本発明のガスバリアバッグは、上記ガスバリアフィルムを前記接着性官能基を有しないフッ素樹脂フィルムが対面するように合わせ、該合わせフィルムの外周辺同士を融着して袋状に形成したことを特徴としている。
これにより、接着性官能基を有しないフッ素樹脂フィルム同士は密着性に優れているため、内容物の漏れが無く、各積層間において優れた密着性を有し、かつ優れたガスバリア性を有するガスバリアバッグとすることができる。
In order to achieve the above object, the gas barrier bag of the present invention is formed in a bag shape by aligning the gas barrier film so that the fluororesin film not having the adhesive functional group faces, and fusing the outer periphery of the laminated film together. It is characterized by the formation.
As a result, since the fluororesin films having no adhesive functional group are excellent in adhesiveness, there is no leakage of the contents, excellent adhesiveness between the respective laminates, and a gas barrier having excellent gas barrier properties It can be a bag.

It was cut out with a width of 15 mm perpendicular to the seal part on one side, and the strength was evaluated in accordance with JIS Z0238 “Test method for heat-sealed soft packaging bags and semi-rigid containers”. The measurement was performed using a tensile tester (manufactured by NMB, TCM-100) at a pulling speed of 300 mm / min.

図3は、実施例1〜4及び比較例1〜2の各多層フィルムのガスバリア性、密着強度の結果を示す図である。実施例1〜3は変性PFAフィルムを用いた場合であるが、ガス透過が少なく、優れたガスバリア性を有しつつ、密着強度も高い。実施例4はLCPフィルムの表面処理なしの場合であるが、優れたガスバリア性を有するが、密着強度が若干低い。このことから、LCPフィルムの表面処理は行った方が好ましいといえる。比較例1は従来のPTFEフィルムの場合であり、ガス透過が多く、ガスバリア性に劣り、密着強度も低い。比較例2は変性PFAフィルムを用いなかった場合であり、優れたガスバリア性を有するが、密着強度が弱く、実用上問題がある。また、実施例1〜4及び比較例1ではバッグの成形性は良好であったが、比較例2ではPFAフィルムとLCPフィルムとの密着が弱く簡単に剥離してしまいバッグとして実用に適さなかった。   FIG. 3 is a diagram showing the results of gas barrier properties and adhesion strength of the multilayer films of Examples 1 to 4 and Comparative Examples 1 and 2. Examples 1 to 3 are cases where a modified PFA film was used, but there was little gas permeation, excellent gas barrier properties, and high adhesion strength. Example 4 is a case where the surface treatment of the LCP film is not performed, but has excellent gas barrier properties, but the adhesion strength is slightly low. From this, it can be said that the surface treatment of the LCP film is preferably performed. Comparative Example 1 is a case of a conventional PTFE film, which has a lot of gas permeation, inferior gas barrier properties, and low adhesion strength. Comparative Example 2 is a case where a modified PFA film was not used, and although it has excellent gas barrier properties, the adhesion strength is weak and there is a problem in practical use. In Examples 1 to 4 and Comparative Example 1, the moldability of the bag was good, but in Comparative Example 2, the adhesion between the PFA film and the LCP film was weak and easily peeled off, which was not suitable for practical use as a bag. .

尚、上述した実施形態では、ガスバリアフィルム1としては、接着性官能基を有しないフッ素樹脂フィルム4/接着性官能基を有するフッ素樹脂フィルム3/LCPフィルム2/接着性官能基を有するフッ素樹脂フィルム3/接着性官能基を有しないフッ素樹脂フィルム4の5層構造としたが、LCPフィルム2/接着性官能基を有するフッ素樹脂フィルム3/接着性官能基を有しないフッ素樹脂フィルム4の3層構造としても同様の効果を得ることができる。
また、ガスバリアバッグ10としては、2枚のガスバリアフィルム1を合わせて外周四辺同士を溶融シールして袋状に形成したが、1枚のガスバリアフィルム1を折り返して外周三辺同士を溶融シールして袋状に形成しても良い。
In the embodiment described above, as the gas barrier film 1, the fluororesin film 4 having no adhesive functional group / the fluororesin film 3 having an adhesive functional group / LCP film 2 / the fluororesin film having an adhesive functional group. 3 / 5-layer structure of fluororesin film 4 having no adhesive functional group, but 3 layers of LCP film 2 / fluororesin film 3 having adhesive functional group 3 / fluororesin film 4 having no adhesive functional group Similar effects can be obtained with the structure.
Further, as the gas barrier bag 10, two gas barrier films 1 are combined and melt-sealed at the four outer sides to form a bag shape, but one gas barrier film 1 is folded and the three outer sides are melt-sealed. You may form in a bag shape.

本発明に係るガスバリアバッグは、フォトレジスト溶液を封入する容器として有効であるが、インク材料、有機EL材料、液晶材料、その他ポリイミド等の樹脂材料等を封入する容器としても適用が可能である。   The gas barrier bag according to the present invention is effective as a container for enclosing a photoresist solution, but can also be applied as a container for enclosing an ink material, an organic EL material, a liquid crystal material, and other resin materials such as polyimide.
