The method for peeling off the polymer film according to this embodiment is
Step A of preparing a laminate in which a polymer film on which a circuit pattern and / or a functional element is formed and an inorganic substrate are in close contact with each other, and
Step B of forming a peeled portion between the polymer film and the inorganic substrate at the end of the laminate,
This includes step C of peeling the polymer film from the inorganic substrate while keeping the polymer film substantially flat by warping the inorganic substrate in a direction away from the polymer film.
本実施形態に係る高分子フィルムの剥離方法においては、まず、回路パターン及び/又は機能素子が形成された高分子フィルムと無機基板とが密着した積層体を準備する(工程A)。図1は、積層体の一例を示す模式断面図である。図1に示すように、積層体10は、無機基板12と高分子フィルム14とを備える。無機基板12と高分子フィルム14とは密着している。無機基板12と高分子フィルム14とは、図示しないシランカップリング剤層を介して密着していてもよい。
高分子フィルム14上には、回路パターン及び/又は機能素子が形成されている(図示せず)。回路パターン及び/又は機能素子は無機基板12と密着していない非密着面上に形成される。つまり、本実施形態では、高分子フィルム14上に、回路パターンと機能素子との両方が形成されていてもよく、回路パターンが形成され且つ機能素子が形成されていなくてもよく、機能素子が形成され且つ回路パターンが形成されていなくてもよい。
前記回路パターンは、従来公知の方法にて形成することができる。前記回路パターンの厚みとしては、通常0.05μm~20μm、好ましくは0.1μm~15μm、より好ましくは0.15μm~0.5μm程度である。
また、図1では無機基板12と高分子フィルム14の厚みは異なるものの同じ大きさで書かれている。高分子フィルム14と無機基板12の大きさが異なり、高分子フィルム14が無機基板12よりも大きくても構わないし、小さくても構わない。高分子フィルム14が無機基板12より小さく作ることは作製上容易であるため、このように大きさが異なっていてもよい。また、剥離を容易にするため、工程Aの後に前記高分子フィルム14と無機基板12とが密着した積層体から外周部のガラスを割断して、除去して、高分子フィルム14が無機基板12より大きくなっていてもよい。
なお、本実施形態では、あらかじめ別途製造した高分子フィルムを無機基板に接着する(積層する)ことにより積層体を得ることができる。積層の方法としては、後述するシランカップリング剤を用いた積層方法の他、既存公知の接着剤、接着シート、粘着剤、粘着シートなどを適用することも可能である。また、この時、前記接着剤、前記接着シート、前記粘着剤、前記粘着シートは、無機基板側に先につけてもよく、高分子フィルム側に先につけてもよい。
また、高分子フィルムと無機基板との積層体を作製する他の方法として、高分子フィルム形成用の高分子溶液あるいは高分子の前駆体の溶液を無機基板に塗布し、乾燥および、必要に応じて化学反応を行い、無機基板上で高分子をフィルム化することにより積層体を得る方法が挙げられる。高分子溶液として可溶性ポリイミドの溶液、高分子前駆体として化学反応によりポリイミドとなるポリアミド酸溶液などを用いることにより、高分子フィルムと無機基板との積層体を得ることができる。またその際に、無機基板にシランカップリング剤処理などの表面処理を行うことにより、高分子フィルムと無機基板との接着性を制御することも好ましい態様の一つである。この時、無機基板と高分子フィルムとの剥離強度をコントロールするため、既知の易剥離な高分子層(易剥離層)と主なる高分子層(高分子フィルム)との2層構成や、主層(高分子フィルム)と無機薄膜層との2層構成としてもよい。その他、剥離力をコントロールための既存の構成を適用してもよい。
易剥離な高分子層(易剥離層)と主なる高分子層(高分子フィルム)との2層構成の場合には、易剥離な高分子層(易剥離層)と無機基板との接着力が易剥離な高分子層(易剥離層)と主なる高分子層(高分子フィルム)との接着力よりも強く接着して、主なる高分子層(高分子フィルム)と易剥離な高分子層(易剥離層)との間で剥離する設計の場合と、易剥離な高分子層(易剥離層)と主なる高分子層(高分子フィルム)との接着力が、易剥離な高分子層(易剥離層)と無機基板との接着力より強く、易剥離な高分子層(易剥離層)と無機基板との間で剥離する設計の場合がある。
易剥離な高分子層(易剥離層)と無機基板との接着力が易剥離な高分子層(易剥離層)と主なる高分子層(高分子フィルム)との接着力より強く接着して、主なる高分子層(高分子フィルム)と易剥離な高分子層(易剥離層)との間で剥離する設計の場合については、無機基板に易剥離な高分子層(易剥離層)が堆積しているものが、本発明における無機基板に相当する。
無機薄膜層との2層構成の場合には、無機薄膜層を無機基板上に製膜して、その後に無機薄膜層の上に溶液あるいは高分子の前駆体の溶液を無機基板に塗布し、乾燥および、必要に応じて化学反応を行い、無機基板上で高分子をフィルム化することにより積層体を得る方法が挙げられる。この場合、無機基板上の無機薄膜と高分子層との間で剥離することになる。この場合、無機基板に無機薄膜が堆積しているものが、本発明における無機基板に相当する。
高分子溶液ないし高分子前駆体溶液を用いる手法の変形として、溶剤を含んだ半固体状態(高粘度ペースト状)の高分子フィルムを無機基板に圧着した後に追乾燥ないし必要に応じて化学反応を行い、高分子フィルムと無機基板との積層体を得ることもできる。より具体的には、ポリエチレンテレフタレートなどの支持フィルム上に目的とする高分子溶液ないし高分子前駆体溶液を塗布し、残溶剤分がウェットベースで5~40質量%程度となるまで半乾燥させることにより、塑性変形性を有する半固体のフィルムとすることができる(グリーンフィルムないしゲルフィルムと呼ばれることもある)。このようにして得られた半固体状態のフィルムを無機基板に圧着し、乾燥と熱処理などを行えば、高分子フィルムと無機基板との積層体を得ることができる。
本実施形態において、熱可塑性の高分子を用いる場合には、高分子を無機基板上に直接溶融押し出しすることにより積層体を得ることができる。また熱可塑性の高分子フィルムの場合には、無機基板と高分子フィルムとを重ね、加圧した状態で高分子の融点ないし軟化温度まで加熱することにより両者を圧着して積層体とすることができる。 <Process A>
In the polymer film peeling method according to the present embodiment, first, a laminate in which the polymer film on which the circuit pattern and / or the functional element is formed and the inorganic substrate are in close contact is prepared (step A). FIG. 1 is a schematic cross-sectional view showing an example of a laminated body. As shown in FIG. 1, the
A circuit pattern and / or a functional element is formed on the polymer film 14 (not shown). The circuit pattern and / or the functional element is formed on a non-contact surface that is not in close contact with the
The circuit pattern can be formed by a conventionally known method. The thickness of the circuit pattern is usually about 0.05 μm to 20 μm, preferably 0.1 μm to 15 μm, and more preferably about 0.15 μm to 0.5 μm.
Further, in FIG. 1, although the thicknesses of the
In this embodiment, a laminated body can be obtained by adhering (laminating) a polymer film separately manufactured in advance to an inorganic substrate. As a laminating method, in addition to a laminating method using a silane coupling agent described later, it is also possible to apply an existing known adhesive, adhesive sheet, adhesive, adhesive sheet or the like. Further, at this time, the adhesive, the adhesive sheet, the pressure-sensitive adhesive, and the pressure-sensitive adhesive sheet may be attached first to the inorganic substrate side or first to the polymer film side.
In addition, as another method for producing a laminate of a polymer film and an inorganic substrate, a polymer solution for forming a polymer film or a solution of a polymer precursor is applied to the inorganic substrate, dried, and if necessary. A method of obtaining a laminate by performing a chemical reaction to form a polymer on an inorganic substrate can be mentioned. By using a soluble polyimide solution as the polymer solution and a polyamic acid solution that becomes polyimide by a chemical reaction as the polymer precursor, a laminate of the polymer film and the inorganic substrate can be obtained. At that time, it is also a preferable aspect to control the adhesiveness between the polymer film and the inorganic substrate by performing a surface treatment such as a silane coupling agent treatment on the inorganic substrate. At this time, in order to control the peeling strength between the inorganic substrate and the polymer film, a two-layer structure consisting of a known easily peelable polymer layer (easy peeling layer) and a main polymer layer (polymer film), or a main It may have a two-layer structure consisting of a layer (polymer film) and an inorganic thin film layer. In addition, an existing configuration for controlling the peeling force may be applied.
In the case of a two-layer structure consisting of an easily peelable polymer layer (easily peeling layer) and a main polymer layer (polymer film), the adhesive force between the easily peeling polymer layer (easily peeling layer) and the inorganic substrate. Is stronger than the adhesive strength between the easily peelable polymer layer (easy peeling layer) and the main polymer layer (polymer film), and is easily peeled off from the main polymer layer (polymer film). In the case of a design that peels off from the layer (easy peeling layer), the adhesive strength between the easy peeling polymer layer (easy peeling layer) and the main polymer layer (polymer film) is a polymer that is easy to peel off. In some cases, it is designed to peel off between the easily peelable polymer layer (easy peeling layer) and the inorganic substrate, which is stronger than the adhesive force between the layer (easily peeling layer) and the inorganic substrate.
The adhesive strength between the easily peelable polymer layer (easy peeling layer) and the inorganic substrate is stronger than the adhesive strength between the easily peelable polymer layer (easy peeling layer) and the main polymer layer (polymer film). In the case of a design that peels off between the main polymer layer (polymer film) and the easily peelable polymer layer (easily peeling layer), the easily peeling polymer layer (easily peeling layer) is provided on the inorganic substrate. What is deposited corresponds to the inorganic substrate in the present invention.
In the case of a two-layer structure with an inorganic thin film layer, the inorganic thin film layer is formed on an inorganic substrate, and then a solution or a polymer precursor solution is applied to the inorganic substrate on the inorganic thin film layer. Examples thereof include a method of obtaining a laminate by drying and, if necessary, performing a chemical reaction to form a film of a polymer on an inorganic substrate. In this case, the inorganic thin film on the inorganic substrate and the polymer layer are separated from each other. In this case, the inorganic thin film deposited on the inorganic substrate corresponds to the inorganic substrate in the present invention.
As a modification of the method using a polymer solution or a polymer precursor solution, a semi-solid state (high-viscosity paste-like) polymer film containing a solvent is pressure-bonded to an inorganic substrate and then dried or chemically reacted as necessary. It is also possible to obtain a laminate of a polymer film and an inorganic substrate. More specifically, the target polymer solution or polymer precursor solution is applied on a support film such as polyethylene terephthalate, and semi-dried until the residual solvent content is about 5 to 40% by mass on a wet base. Therefore, a semi-solid film having plastic deformability can be obtained (sometimes called a green film or a gel film). When the semi-solid film thus obtained is pressure-bonded to an inorganic substrate and dried and heat-treated, a laminate of the polymer film and the inorganic substrate can be obtained.
In the present embodiment, when a thermoplastic polymer is used, a laminate can be obtained by directly melt-extruding the polymer onto an inorganic substrate. In the case of a thermoplastic polymer film, the inorganic substrate and the polymer film can be layered and heated to the melting point or softening temperature of the polymer under pressure to press them together to form a laminate. can.

図2は、第1実施形態に係る剥離装置の模式断面図である。図2に示すように、第1実施形態に係る剥離装置20は、真空チャンバー30と、ローラー32と、真空チャック34と、基板接触子35とを備える。 [First Embodiment]
FIG. 2 is a schematic cross-sectional view of the peeling device according to the first embodiment. As shown in FIG. 2, the peeling
なお、この状態では、ローラー32が高分子フィルム14を剥離部分18方向に基板接触子35越しに押圧しているため、剥離は進行しない。 Next, the peeling
In this state, since the
このように、剥離装置20では、ローラー32および基板接触子35の面を無機基板12の非密着面12aに対して平行に移動させ、ローラー32の移動に応じて剥離を進行させるため、剥離スピードをコントロールすることができる。その結果、無機基板12や高分子フィルム14に過度の負荷が掛かることを抑制することができる。積層体10の押上には、ローラー32または基板接触子35のいずれかであれば良く、好ましくはローラー35および基板接触子35の両方である。
さらにローラー32の半径を変化させることにより、無機基板12の剥離角度をコントロールすることができる。例えば、ローラー32の半径を小さくすれば、無機基板12はそれに従った曲率半径で剥離し、ローラー32の半径を大きくすれば、無機基板12はそれに従った曲率半径で剥離する。ローラー32の半径を小さくすることで剥離装置20を小型化することができ、ローラー32の半径を大きくすることで、無機基板12に加わる曲げの負荷を小さくすることができる。
なお、真空チャンバー30及び真空チャック34は、本発明の静圧差形成手段に相当する。
前記ローラーの半径は、40mm以上、1000mm以下であり、より好ましくは60mm以上、100mm以下である。
前記ローラーの材質としては、ある程度の弾性を有する材質が好ましく、例えば、シリコーンゴム、フッ素ゴム、ウレタンゴム、エチレンプロピレンゴム等を用いることができる。

The radius of the roller is 40 mm or more and 1000 mm or less, more preferably 60 mm or more and 100 mm or less.
As the material of the roller, a material having a certain degree of elasticity is preferable, and for example, silicone rubber, fluororubber, urethane rubber, ethylene propylene rubber and the like can be used.
The elastic modulus of the roller material (JIS K 6255: 2013) is preferably 3 to 60%.
The rubber hardness of the roller material is preferably 50 to 90, preferably non-adhesive and antistatic or conductive.
前記メッシュ状シートの材質としては、適度に弾性変形する材質であることが好ましく、具体的にはポリエステルフィラメント、ナイロンフィラメント、ステンレスワイヤ等が用いられたメッシュカウント#80以上#600以下の範囲のメッシュ状シートであることが好ましい。また、帯電防止または導電性のものであることが好ましい。

The material of the mesh-like sheet is preferably a material that is appropriately elastically deformed, and specifically, a mesh having a mesh count of # 80 or more and # 600 or less using a polyester filament, a nylon filament, a stainless wire, or the like. It is preferably a shaped sheet. Further, it is preferably antistatic or conductive.
In the present embodiment, the case where the mesh-shaped
なお本明細書における剥離角度はメッシュ厚、フィルム厚、および、ローラーの半径に依存する。剥離するフィルム厚に応じて適切なメッシュ厚とローラー半径を選択することで、剥離角度を所定の範囲に収めることができる。
本実施形態では、剥離後の高分子フィルムと無機基板は、ローラーで押されていないため概略平行で数mm離れている。そのため、一旦剥離した高分子フィルムは真空吸着されたまま無機基板とは再度接触しない。 It is preferable to control the peeling angle between the polymer film (where the functional element is formed) and the inorganic substrate to be 1 degree or more and 30 degrees or less. More preferably, it is 1 degree or more and 10 degrees or less. By keeping it within the above range, it is possible to efficiently perform peeling without damaging the functional element.
The peeling angle in the present specification depends on the mesh thickness, the film thickness, and the radius of the roller. By selecting an appropriate mesh thickness and roller radius according to the film thickness to be peeled off, the peeling angle can be kept within a predetermined range.
In the present embodiment, the polymer film and the inorganic substrate after peeling are substantially parallel and separated by several mm because they are not pressed by the rollers. Therefore, the polymer film once peeled off does not come into contact with the inorganic substrate again while being vacuum-adsorbed.

高圧力とはエアーブローノズル45から供給される気体の圧力によって剥離部分に生じる圧力のことを指す。
隔壁31は前記積層体10の側面に設けられている。隔壁31とはエアーブローノズル45から供給される気体の圧力が無機基板の非密着面12a側に漏れないように両者を分離するための壁を言う。ここで、側面とは積層体10の厚み方向と平行になる位置をいう。また、隔壁31が積層体10の側面に存在することで、剥離部分18に気体を注入した際、剥離部分18と、無機基板の非密着面12aとの圧力差を概略維持することができる。さらに、前記無機基板12の動きを前記高分子フィルム14から離れる方向のみに制限することができる。離れる方向の動きとは剥離の時に高分子フィルム14平面に対して、概略垂直方向で無機基板12と高分子フィルム14の距離が大きくなる動きのことを指す。高圧力と低圧力は隔壁31があることによって分離されている。
前記気体は、特に限定されず、空気、窒素、ヘリウム、ネオン、アルゴン等を使用することができる。 Here, the low pressure refers to a pressure lower than the pressure of the gas supplied from the
The high pressure refers to the pressure generated in the peeled portion by the pressure of the gas supplied from the
The
The gas is not particularly limited, and air, nitrogen, helium, neon, argon and the like can be used.
図20~図24は、第8実施形態に係る剥離装置の変形例の模式断面図である。図20~図24に示すように、第8実施形態に係る剥離装置24、25、26、27,28は、上記で説明した剥離装置20に対して、無機基板12の保持機構として、隔壁サポートパーツ33が無い。このため、剥離した無機基板12のエッジ(端部)より高圧力の気体が無機基板の非密着面12aに移動しうる。このため、隔壁31の材質を選択する、無機基板12と隔壁31の間隔を狭くするあるいは、上壁に空白部を作ることで大気開放とする、上壁から真空ポンプによって吸引する、といった方策で剥離部分と18と無機基板の非密着面12aの圧力差を維持することで、剥離を実現できる。上壁39に無機基板12が沿うことによって、機械的に無機基板12の最小曲率半径より曲げないように制限している。これにより、剥離時の無機基板12への負荷を低減することができる。特に剥離装置27のように、上壁39を、真空チャック34と平行ではあるが、やや斜めにすることで無機基板が剥離するときの動ける範囲を制限することができる。このようにすることで無機基板の剥離時の動きを制限することも有効な手段である。また、剥離装置28では、Oリング63を使って真空チャック34と上壁39を隔壁31との間で結合させ、厳密にエアー漏れを防ぐ構造を取っている。これも有効な手段である。 [Eighth Embodiment]

Hereinafter, step B is a case where "at the end portion of the laminate, a gas is blown to a region including a boundary between the polymer film and the inorganic substrate to form a peeling region at the end portion". Will be described as the tenth to eleventh embodiments.
<工程A>
第10実施形態に係る高分子フィルムの剥離方法においては、まず、高分子フィルムと無機基板とが密着した積層体を準備する(工程A)。図27は、積層体の一例を示す模式断面図であり、図28は、その平面図である。図27、図28に示すように、積層体110は、無機基板112と高分子フィルム114とを備える。無機基板112と高分子フィルム114とは密着している。無機基板112と高分子フィルム114とは、図示しないシランカップリング剤層を介して密着していてもよい。
高分子フィルム114上には、回路パターン及び/又は機能素子が形成されている(図示せず)。つまり、本実施形態では、高分子フィルム114上に、回路パターンと機能素子との両方が形成されていてもよく、回路パターンが形成され且つ機能素子が形成されていなくてもよく、機能素子が形成され且つ回路パターンが形成されていなくてもよい。
前記回路パターンは、従来公知の方法にて形成することができる。前記回路パターンの厚みとしては、通常0.05μm~20μm、好ましくは0.1μm~15μm、より好ましくは0.15μm~0.5μm程度である。 [10th Embodiment]
