- This invention makes it a subject to provide the flexible laminate which can suppress effectively the fall of peel strength, when manufacturing a flexible laminate (especially 2 layer metalizing laminated body).
- the adhesive-free flexible laminate according to 1) above wherein an atomic fraction of Cu mixed in the tie coat layer is 0.1 at% or less.
- the tie coat layer is made of any one of nickel, chromium, cobalt, nickel alloy, chromium alloy, and cobalt alloy, and the main component is nickel, chromium, or cobalt. 4.
- a flexible laminate substrate is produced by forming a tie coat layer on at least one surface of the polyimide film and further forming a metal conductor layer on the surface.
- the surface of the polyimide film is subjected to plasma treatment to remove surface contaminants and to modify the surface.
- a tie coat layer is formed on the modified polyimide surface, and a metal seed layer is formed thereon by sputtering.
- a metal layer to be a conductor layer of the circuit board is formed by electroless plating or electroplating.
- FIG. 1 shows a configuration of a roll-to-roll sputtering apparatus generally used industrially when producing FCCL by the metalizing method.
- the film is continuously conveyed while being wound around a drum from right to left.
- a Ni—Cr layer is formed as a tie coat layer and a case where a Cu layer is further formed as an example, in FIG. 1, all the sputtering units of the Ni—Cr sputtering unit and the plurality of Cu sputtering units are operated. Thus, a Ni—Cr film and a Cu film thereon are continuously formed on the film. Each film thickness is controlled by supplying necessary power to each sputtering unit for a predetermined film feed speed.
- the thickness of the Ni—Cr film is preferably thicker from the standpoint of adhesion to polyimide and copper diffusion barrier, but it is thin from the standpoint of etchability when FCCL is etched to produce a printed circuit board. Is preferable. From this viewpoint, a thickness of about 5 to 50 nm, more preferably 10 to 30 nm is formed.
- the desired film thickness of the Cu film subsequently formed on the Ni—Cr film is preferably thicker because the Cu film functions as a conductive layer and a cathode for electroplating in a later process, but is not so much from the viewpoint of productivity. It is not realistic to make it thicker. From this viewpoint, the thickness is usually 50 to 1000 nm, more preferably 150 to 500 nm. However, it goes without saying that the above-mentioned film thickness can be appropriately adjusted according to the purpose.
- Ni—Cr film and the Cu film are formed under the condition that the film is transported at the same speed, a plurality of Cu sputtering units are required to obtain the respective desired film thicknesses described above.
- the number of Ni—Cr sputtering units is 2 to 6 times as many.
- the following two mechanisms are conceivable as Cu mixing into the tie coat layer.
- the degree of reduction is to reduce the power (sputtering amount) of the Cu sputter unit adjacent to Ni—Cr as much as possible to reduce the mixing ratio, and as much as possible the Cu sputter unit and Ni—Cr sputter unit Measures such as increasing the distance can be considered.
- the degree of reduction is to reduce the power (sputtering amount) of the Cu sputter unit adjacent to Ni—Cr as much as possible to reduce the mixing ratio, and as much as possible the Cu sputter unit and Ni—Cr sputter unit Measures such as increasing the distance can be considered.
- the device becomes unnecessarily enlarged, and there is a gap between the formation of the Ni—Cr film and the formation of the Cu film, and the Ni—Cr film becomes a residual gas or film in the device. Therefore, it cannot be said to be a preferable method such as oxidation due to the influence of moisture inevitably generated from water.
- the energy of Cu atoms in the first Cu sputtering unit is reduced after the Ni—Cr film is formed. Since the energy per sputtered Cu atom is generally proportional to the sputtering voltage, it is sufficient to take measures to lower the sputtering voltage. For this purpose, measures such as lowering the input power, increasing the sputtering pressure, and strengthening the magnetic field of magnetron sputtering can be cited.
- measures such as lowering the input power, increasing the sputtering pressure, and strengthening the magnetic field of magnetron sputtering can be cited.
- changing the sputtering pressure affects the sputtered film quality, so it is not a condition that can be determined only by countermeasures against contamination. Strengthening the magnetic field of magnetron sputtering is likely to cause a decrease in target utilization efficiency, resulting in cost disadvantages. is there.
- any of the mechanisms (A) and (B) it is an effective method to reduce the power of the Cu sputter unit adjacent to the Ni—Cr sputter unit.
- the reduction can be compensated for by the power of the remaining Cu sputter units. There is an advantage that there is no need to reduce the Cu film thickness.
- the tie coat layer formed on the polyimide surface is formed to suppress copper diffusion, but it is inevitable that copper is mixed into the tie coat layer in the sputtering film forming step.
- the explanation and the fact that it is effective to lower the power of the Cu sputter unit adjacent to the sputter unit for forming the tie coat layer as a means for minimizing the amount of copper mixed into the tie coat layer have been explained.
- an adhesive-free agent that can suppress a decrease in peel strength by determining the limit value of the amount of Cu contained in the tie coat layer relative to the main component M of the tie coat layer, regardless of the size of the apparatus and the film forming conditions.
- a flexible laminate can be provided.
- the amount of Cu contained in the tie coat layer can be controlled by setting the power of the Cu sputter unit adjacent to the sputter unit that forms the tie coat layer, as shown in the examples below. This is a limit value of the amount of Cu contained in the tie coat layer with respect to the main component M of the layer, and countermeasures for reducing Cu contamination by other methods in actual apparatus configuration and conditions can be appropriately taken.
- the present invention has obtained the knowledge that copper is mixed into the tie coat layer in the actual sputtering film forming process, even though a metal not containing copper is selected as the tie coat layer. Based on. Therefore, it is important to know the harmful range of the amount of copper contained in the tie coat layer, and by controlling the amount of copper that excludes this harmful range, flexible laminates (especially two-layer metal In the case of producing a (rising laminate), it is possible to suppress a decrease in peel strength.
- the wiring width is narrower, and when the line width is narrow, it is more susceptible to etching, and moreover, there is an increasing number of thermal loads in circuit design. Even under such conditions, it can be said that it is desirable to improve not only the peel strength, that is, the normal peel strength but also the heat-resistant peel strength.
- the adhesiveless flexible laminate of the present invention has an atomic fraction of Cu mixed in the tie coat layer of 0.5 at% or less. If it exceeds 0.5 at%, the effect of suppressing peel strength is small.
- the atomic fraction of mixed Cu in the tie coat layer is 0.3 at% or less, and further that the atomic fraction of mixed Cu in the tie coat layer is 0.1 at% or less.
- the material used for the tie-coat layer is any one of nickel, chromium, cobalt, nickel alloy, chromium alloy, and cobalt alloy, and it is desirable that the presence of copper be less as an impurity.
- nickel, chromium or cobalt is the main component, and these are components having the largest abundance ratio in the tie coat layer.
- the flexible electronic circuit board formed using said non-adhesive flexible laminate can be provided.
- Example 1 After setting the polyimide film in a vacuum device evacuated it was carried out plasma treatment of the polyimide. Subsequently, a tie coat layer and a metal seed layer were formed by sputtering.
- the tie coat layer was Ni-20 wt% Cr: theoretical density equivalent to 25 nm, and the metal seed layer was Cu: 300 nm.
- Sputtering was performed by DC magnetron method in an Ar gas atmosphere at 0.5 Pa. One Ni—Cr sputter unit and three Cu sputter units were used, and the sum of the power of the three Cu sputter units was adjusted to be constant.
- a metal conductor layer (thickness 8 ⁇ m) made of copper was formed on the above metal seed layer by electroplating to produce a two-layer metalizing laminate.
- FIG. 2 is a plot of the amount of Cu mixed in Ni—Cr, with the horizontal axis representing the ratio of each power during operation of the adjacent Ni—Cr sputtering unit and Cu sputtering unit.
- the amount of Cu mixed in Ni—Cr was quantified by the following procedure. First, the prepared FCCL was accurately cut into a 5 cm square, and the copper layer was removed with nitric acid to expose the Ni—Cr layer. Thereafter, the entire Ni—Cr layer was dissolved with 18 ml of 35% hydrochloric acid, and diluted with pure water to give a total of 50 ml solution to prepare a Cu content analysis solution in Ni—Cr. Then, the amount of Cu in this solution was quantitatively analyzed by ICP-MS (manufactured by SII, model SPQ-9700), and the ratio to the total dissolved Ni—Cr was taken as the amount of mixed Cu.
- ICP-MS manufactured by SII, model SPQ-9700
- the power of the sputter unit and the film feed rate were kept constant, and the power of the Cu sputter unit adjacent to Ni—Cr was changed. Further, as described above, the sum of the electric power of the three Cu sputter units is constant.
- the power ratio of Cu / (Ni—Cr) sputtering is around 0.00-2.20, the amount of mixed copper gradually increases from 0.1-0.3 at%, but rapidly increases from around 2.50. It can be seen that the amount of mixed copper exceeds 0.5 at%.
- this Cu / (Ni—Cr) tendency depends only on the sputtering apparatus / conditions and not on the type of polyimide. Actually, the same tendency was shown regardless of the type of polyimide film.
- the increase in the numerical value on the horizontal axis in FIG. 2 means that the Cu sputtering input power adjacent to Ni—Cr is larger than the sputtering input power for forming the (Ni—Cr) tie coat layer. It can be seen that reducing the electric power as much as possible is an effective means for suppressing the mixing of Cu.
- Example 2 Under the following conditions, a two-layer metalizing laminate was prepared in the same process as in Example 1, and the peel strength was measured. The peel strength was measured according to JISC6471 (copper-clad laminate test method for flexible printed wiring boards).
- FIG. 3 shows the peel strength measured with respect to the Cu content (Cu / Ni) in the Ni—Cr layer using a Kapton-150EN polyimide film manufactured by Toray DuPont.
- the normal peel strength is 0.7 kN / m.
- the normal peel strength is 0.6 kN / m or more, so it can be said that there is no significant influence.
- the amount of Cu mixed in the Ni—Cr layer is 0.10 at% or less, it is effective in improving the normal peel strength.
- the amount of Cu mixed in the Ni—Cr layer had a great influence on the peel strength after heat-resistant Aging. That is, a decrease in peel strength after heat-resistant Aging was observed from 0.10 at% in the Ni—Cr layer, and the peel strength was 0.4 kN / m or less when the Cu mixing amount was 0.30 at%. The tendency continued until the Cu mixing amount decreased to 0.50 at%, and the peel strength reached around 0.3 kN / m.
- any other metal or alloy that is a tie coat layer ie, nickel, chromium, cobalt, nickel alloy, chromium alloy, or cobalt alloy. It was confirmed that the same result was obtained even in the case of a tie coat layer composed of only one kind and mainly composed of nickel, chromium or cobalt.
- the atomic fraction of mixed Cu in the tie coat layer should be 0.5 at% or less, preferably the atomic fraction of mixed Cu in the tie coat layer should be 0.3 at% or less, and further the tie coat It can be seen that it is particularly desirable that the atomic fraction of the mixed Cu in the layer is 0.1 at% or less.
- the line width is 3 mm, but the wiring width of an actual printed circuit board (especially for COF) is as narrow as several tens of microns. In general, as the line width is narrower, the peel strength is more sensitive to various conditions. Therefore, it can be seen that this condition, which produces an effect even at a line width of 3 mm, is extremely effective.
- Example 3 Under the following conditions, a two-layer metalizing laminate was produced in the same process as in Example 1, and the peel strength was measured. The peel strength was measured according to JISC6471 (copper-clad laminate test method for flexible printed wiring boards).
- FIG. 4 shows the peel strength measured with respect to the amount of Cu mixed in the Ni—Cr layer (Cu / Ni) using Ube Industries' Upilex-35SGA polyimide film.
- the normal peel strength does not change greatly with respect to the amount of Cu mixed in the Ni—Cr layer, but the heat-resistant peel strength is 0.10 at% when the amount of Cu mixed in the Ni—Cr layer.
- the peel strength after heat-resistant Aging gradually decreased from 0.30 at% to 0.30 at%, and when the Cu mixing amount exceeded 0.50 at%, the peel strength reached less than 0.5 kN / m.
- any other metal or alloy that is a tie coat layer ie, nickel, chromium, cobalt, nickel alloy, chromium alloy, or cobalt alloy. It was confirmed that the same result was obtained even in the case of a tie coat layer consisting of only one kind and mainly composed of nickel, chromium or cobalt.
- the atomic fraction of the mixed Cu in the tie coat layer is 0.5 at% or less, preferably the atomic fraction of the mixed Cu in the tie coat layer is 0.3 at% or less. Furthermore, it can be seen that it is particularly desirable that the atomic fraction of Cu mixed in the tie coat layer is 0.1 at% or less. In particular, it was confirmed that it was effective for improving the heat-resistant peel strength. Since the peel strength is more sensitive to various conditions as the line width is narrower, it can be estimated that this tendency is more effective as the line width is reduced.
- the present invention is superior in that it can suppress a decrease in peel strength when a flexible laminate (particularly a two-layer metallized laminate) is produced by controlling the amount of copper contained in the tie coat layer. Therefore, it is useful as a material for circuit boards in the electronics industry.

Abstract
Description
ところが、銅の拡散を抑止するためのタイコート層を設けたにもかかわらず、ピール強度の低下があり、その原因の究明が必要であった。
1)少なくとも一方の面をプラズマ処理したポリイミドフィルム、プラズマ処理されたポリイミドフィルムの面に形成したタイコート層、タイコート層上に形成した銅又は銅合金のいずれか1種からなる金属シード層、さらに金属シード層上に形成した銅又は銅合金のいずれか1種からなる金属導体層からなる無接着剤フレキシブルラミネートであって、前記タイコート層中の混入Cuの原子分率が0.5at%以下であることを特徴とする無接着剤フレキシブルラミネート

3)前記タイコート層中の混入Cuの原子分率が0.1at%以下であることを特徴であることを特徴とする前記1)記載の無接着剤フレキシブルラミネート。
4)前記タイコート層が、ニッケル、クロム、コバルト、ニッケル合金、クロム合金、コバルト合金のいずれか1種からなり、ニッケル、クロム又はコバルトが主成分であり、前記タイコート層において、これらの主成分が最も存在比の大きい成分であることを特徴とする前記1)~3)のいずれか一項に記載の無接着剤フレキシブルラミネート。
5)前記タイコート層が、ニッケルとクロムとの合金からなり、主成分MがNiであることを特徴とする前記4)に記載の無接着剤フレキシブルラミネート。
6)前記1)~5)のいずれか一項に記載の無接着剤フレキシブルラミネートを用いて形成したフレキシブル電子回路基板、を提供する。
次に改質したポリイミド表面にタイコート層と、その上に金属シード層をスパッタリングにより形成する。次いで無電解めっき又は電気めっきにより回路基板の導体層となる金属層を製膜する。
その機構を以下説明する。図1はメタライジング法でFCCLを生産するに際し一般的に工業的に用いられるロールtoロールのスパッタリング装置の構成を示す。図1において、フィルムは右から左にドラムに巻きつけられながら連続的に搬送される。
其々の膜厚は所定のフィルム送り速度に対して必要な電力を各スパッタユニットに供給することにより制御する。
スパッタリング工程において、タイコート層中にCuが混入する機構として以下の二つが考えられる。
スパッタリングは0.5Pa程度の真空度にて行われるプロセスであり、この圧力領域では気体は粘性のない分子流として振舞う。気体分子の動きは、したがってランダムである。
ターゲットからスパッタされた金属原子(Ni, Cr, Cu)は概ねドラム/フィルム方向に向かうように装置設計されているが、平板ターゲットでのスパッタリングでは指向性はあまり強くないことに加え、気体分子による散乱等の影響により、その量は限られているものの、あらゆる方向に飛び散ることになる。
そして、この飛散したCuがNi-Crスパッタ領域に侵入した場合、Ni-Cr膜へのCu混入が発生すると考えられる。
Cuスパッタ領域に来た時点で、フィルム表面には所望の膜厚のNi-Cr膜が既に形成されているが、ターゲットからスパッタにより飛び出したCu原子は高いエネルギーを持っており、Cu原子がNi-Cr膜表面に単に付着するのではなく、Ni-Cr膜内部にまで打ち込まれることが起こり得る。
当然、ある程度の仕切りは設けられているものの(仕切りは図1では省略)、ドラム近傍の空間ではNi-CrとCuとは完全には切り離されない。したがって完全に混入を抑止することは極めて困難と言える。
このうち、CuスパッタユニットとNi-Crスパッタユニット距離を離すためには、既存の装置への対策としては装置改造を伴うため現実的ではない。また、新規製作の装置としても、いたずらに装置が肥大化すること、またNi-Cr膜成膜後、Cu膜成膜までの間に空白が生じNi-Cr膜が装置内の残留ガスやフィルムから不可避的に発生する水分の影響で酸化するなど、好ましい方法とは言えない。
スパッタされたCu原子1個あたりのエネルギーは概ねスパッタ電圧に比例するので、スパッタ電圧を下げるような対策を講じればよい。そのためには、投入電力を下げること、スパッタ圧力を上げる、マグネトロンスパッタの磁場強化等の対策が挙げられる。
これら対策の内、スパッタ圧力の変更はスパッタ膜質に影響を与えるため混入対策のみで決められる条件ではないこと、マグネトロンスパッタの磁場強化はターゲット利用効率の低下を引き起こし易くコストデメリットを生じるのが難点である。
タイコート層に含まれるCuの量は、下記の実施例に示すように、タイコート層を形成するスパッタユニットに隣接するCuスパッタユニットの電力の設定で制御できるが、重要なことは、タイコート層の主成分Mに対するタイコート層に含まれるCuの量の限界値であって、現実の装置構成、条件での他の方法によるCu混入低減対策も適宜採り得る。
したがって、重要なことはタイコート層中に含有する銅の量の有害な範囲を知ることであり、この有害な範囲を排除した銅の量をコントロールすることによって、フレキシブルラミネート(特に、二層メタライジング積層体)を製作する場合にピール強度の低下を抑制することが可能となる。
いずれの場合も、ニッケル、クロム又はコバルトが主成分となるものであり、これらが前記タイコート層において主成分が最も存在比の大きい成分である。
この中で、特に通常使用されるニッケルとクロムとの合金からなり、主成分がNiであることが望ましい。
さらに、本発明においては、上記の無接着剤フレキシブルラミネートを用いて形成したフレキシブル電子回路基板を提供することができる。
ポリイミドフィルムを真空装置内にセットし真空排気後、ポリイミドのプラズマ処理を実施した。続いてタイコート層および金属シード層をスパッタリングにより形成した。
タイコート層はNi-20wt%Cr:理論密度で25nm相当、金属シード層はCu:300nmとした。スパッタリングはDCマグネトロン方式によりArガス雰囲気、0.5Paにて行った。Ni-Crスパッタユニットは1台、Cuスパッタユニットは3台を使用し、Cuスパッタユニット3台の電力の和は一定となるように調整した。
次に、上記の金属シード層の上に電気メッキにより銅からなる金属導体層(厚さ8μm)を形成することにより、二層メタライジング積層体を作製した。
ここで、Ni-Cr中に混入したCuの量は、下記の手順で定量した。まず作製したFCCLを正確に5cm角に切り出し、その銅層を硝酸で除去しNi-Cr層を露出させた。その後、35%塩酸18mlでNi-Cr層を全て溶解し、純水にてトータル50ml溶液となるように希釈してNi-Cr中のCu量分析溶液を作製した。
そして、この溶液中のCu量を、ICP-MS(SII製、型式SPQ-9700)にて定量分析し、溶解した全Ni-Crとの比をCu混入量とした。
図2の横軸の数値が増加するということは、Ni-Crに隣接するCuスパッタリング投入電力が(Ni-Cr)タイコート層を形成するスパッタリング投入電力よりも大きいことを意味し、Cuスパッタリング投入電力を極力小さくすることが、Cuの混入を抑制する有効な手段であることが分かる。
以下の条件で、実施例1と同様の工程で二層メタライジング積層体を作製し、ピール強度を測定したものである。ピール強度はJISC6471(フレキシブルプリント配線板用銅張積層板試験方法)により実施した。
・フィルム:東レデュポン製Kapton-150EN
・タイコート:Ni-20wt%Cr、25nm
・Cuシード層:300nm
・Cuメッキ層:8μm
・ピール測定時のサンプル線幅:3mm
・耐熱Aging条件:空気中150℃×168時間
この結果、図3に示すように、常態ピール強度の測定におけるCu混入量の依存性については、Ni-Cr層中のCu混入量が0.10at%以下では、常態ピール強度が0.7kN/mを超えていた。その後、Ni-Cr層中のCu混入量が増えても、常態ピール強度が0.6kN/m以上を有しているので、それほど大きな影響はないと言える。しかし、Ni-Cr層中のCu混入量が0.10at%以下では、常態ピール強度の向上に有効であることが分かる。
本実施例は線幅が3mmの場合であるが、現実のプリント基板(特にCOF用途)の配線幅は数十ミクロンと狭い。一般に線幅が狭いほど、ピール強度は種々の条件に敏感であるため、線幅3mmでも効果が発現する本条件は、極めて有効であることが分かる。
以下の条件で、実施例1と同様の工程で二層メタライジング積層体を作製し、ピール強度を測定した。ピール強度はJISC6471(フレキシブルプリント配線板用銅張積層板試験方法)により実施した。
・フィルム:宇部興産製Upilex-35SGA
・タイコート:Ni-20wt%Cr、25nm
・Cuシード層:300nm
・Cuメッキ層:8μm
・ピール測定時のサンプル線幅:100μm
・耐熱Aging条件:空気中150℃×168時間
特に、耐熱ピール強度向上に有効であることが確認できた。線幅が狭いほどピール強度は種々の条件に敏感であるため、この傾向は、線幅が縮小するほど効果があることが推測できる。
