Description
ポリアミド酸は後述の通り、ジアミン化合物と酸二無水物との反応により合成することができる。一般式(3)~(6)中のWとYはジアミン化合物の構造成分を表しており、XとZは酸二無水物の構造成分を表している。
一方、一般式(4)および(6)中のZは、炭素数2以上の4価の有機基を示す。ただし、一般式(4)および(6)で表されるポリアミド酸ブロックは、それぞれYとして一般式(7)で表される2価の有機基を含みかつZとして一般式(8)または(9)で表される4価の有機基を含むポリアミド酸ブロックを除く。このような構成をとり得る酸二無水物としては、一般式(8)および(9)の構造をもたない酸二無水物であればかまわない。例えば、3,3’,4,4’-ビフェニルテトラカルボン酸二無水物、2,3,3’,4’-ビフェニルテトラカルボン酸二無水物、2,2’,3,3’-ビフェニルテトラカルボン酸二無水物、2,2-ビス(3,4-ジカルボキシフェニル)プロパン二無水物、2,2-ビス(2,3-ジカルボキシフェニル)プロパン二無水物、1,1-ビス(3,4-ジカルボキシフェニル)エタン二無水物、1,1-ビス(2,3-ジカルボキシフェニル)エタン二無水物、ビス(3,4-ジカルボキシフェニル)メタン二無水物、ビス(2,3-ジカルボキシフェニル)メタン二無水物、ビス(3,4-ジカルボキシフェニル)エーテル二無水物、2,2-ビス(4-(4-アミノフェノキシ)フェニル)プロパン、1,2,5,6-ナフタレンテトラカルボン酸二無水物、2,3,6,7-ナフタレンテトラカルボン酸二無水物、2,3,5,6-ピリジンテトラカルボン酸二無水物、3,4,9,10-ペリレンテトラカルボン酸二無水物、2,2-ビス(3,4-ジカルボキシフェニル)ヘキサフルオロプロパンニ無水物、2,2-ビス(4-(3,4-ジカルボキシフェノキシ)フェニル)ヘキサフルオロプロパン二無水物、2,2-ビス(4-(3,4-ジカルボキシベンゾイルオキシ)フェニル)ヘキサフルオロプロパン二無水物、2,2’-ビス(トリフルオロメチル)-4,4’-ビス(3,4-ジカルボキシフェノキシ)ビフェニル二無水物、“リカシッド”(登録商標)TMEG-100(商品名、新日本理化(株)製)などの芳香族テトラカルボン酸二無水物や、シクロブタンテトラカルボン酸二無水物、1,2,3,4-シクロペンタンテトラカルボン酸二無水物、2,3,5,6-シクロヘキサンテトラカルボン酸二無水物、5-(2,5-ジオキソテトラヒドロ-3-フラニル)-3-メチル-3-シクロヘキセン-1,2-ジカルボンサン無水物、及び“リカシッド”(登録商標)TDA-100、BT-100(以上、商品名、新日本理化(株)製)などの脂肪族のテトラカルボン酸二無水物を挙げることができる。このうち、耐熱性の点から芳香族酸二無水物が好ましい。より好ましくは、Zとして一般式(10)で表される有機基を主成分とする酸二無水物がよい。R6およびR7は、炭素数1~10の有機基を示し、より具体的には炭素数1~10の炭化水素基、炭素数1~10のアルコキシ基、およびそれらの水素原子がハロゲン等で置換された基が挙げられる。このような構成をとり得る酸二無水物としては、3,3’,4,4’-ビフェニルテトラカルボン酸二無水物、およびその置換誘導体を挙げることができる。このうち、広く市販され、手に入れやすい観点から3,3’,4,4’-ビフェニルテトラカルボン酸二無水物が好ましい。これら酸二無水物は単独、または2種以上を組み合わせて使用することができる。また、Zとして一般式(10)で表される4価の有機基を主成分とする酸二無水物を50%以上の割合で用いることが好ましい。より好ましくは70%以上であり、さらに好ましくは90%以上である。
ポリアミド酸は溶液中において、アミド酸部位が解離して酸無水物基とアミノ基が生成する反応と、それらが再結合する反応とが平衡状態にある。しかし、生成した酸無水物基が溶液中に存在する水分と反応するとジカルボン酸になるため、アミンと再結合できなくなる。そのため、水分の存在によりポリアミド酸は解離する方向に平衡が傾き、ポリアミド酸の重合度が低下する傾向があり、その結果、溶液の粘度が低下することが多い。
また一般式(5)中のmはブロックCおよびC’に含まれる構造単位の繰り返し数を示し、一般式(6)中のnはブロックDに含まれる構造単位の繰り返し数を示す。mおよびnは正の整数を示し、n/m≧0.5であることが好ましい。より好ましくはn/m≧1、さらに好ましくはn/m≧2である。n/n≧0.5であれば、ブロックCおよびC’で解離が起こっても分子量が大幅に低下するのを防ぐことができる。その結果、ポリアミド酸溶液は安定した粘度を保つことができ、保存安定性が向上する。
あるいは、一般式(1)で表されるポリアミド酸は、一般式(13)で表される酸二無水物1モル当量に対して、一般式(14)で表されるジアミン化合物1.00~2モル当量および末端封止剤0.01~1モル当量を反応させたものと、一般式(15)で表されるジアミン化合物1モル当量に対して、一般式(16)で表される酸二無水物1.01~2モル当量を反応させたものとを別々に調整し、次いで両者を混合して反応させることにより得ることができる。その際、一般式(15)で表されるジアミン化合物として、Yが一般式(7)で表される2価の有機基を含むもの以外のものを用いるか、または一般式(16)で表される酸二無水物として、Zが一般式(8)で表されるものおよび(9)で表されるもののいずれかで表される4価の有機基を含むもの以外のものを用いる。
まず、ポリアミド酸樹脂組成物を基板上に塗布する。基板としては例えばシリコンウエハ、セラミックス類、ガリウムヒ素、ソーダ石灰硝子、無アルカリ硝子などが用いられるが、これらに限定されない。塗布方法は、例えば、スリットダイコート法、スピンコート法、スプレーコート法、ロールコート法、バーコート法などの方法があり、これらの手法を組み合わせて塗布してもかまわない。
粘度計(東機産業株式会社製、TVE-22H)を用い、25℃にて測定を行った。
ゲルパーミエーションクロマトグラフィー(日本ウォーターズ株式会社製 Waters 2690)を用い、ポリスチレン換算で重量平均分子量を求めた。カラムは東ソー(株)製 TOSOH TXK-GEL α-2500、およびα-4000を用い、移動層にはNMPを用いた。
実施例で合成したポリアミド酸樹脂組成物(以下、ワニスという)を、2850~3150mPa・sの粘度になるようにNMPを用いて調整した。粘度調整後、恒温庫(アズワン株式会社製 クールインキュベーターPCI-301)にて、40℃で24時間試験した。(以下、この試験を行う前のものを試験前、試験を行った後のものを試験後という)
(4)粘度変化率の算出
保存安定性評価試験後のワニスの粘度を測定し、下記式によって変化率を算出した。
変化率(%)=(試験前の粘度-試験後の粘度)/試験前の粘度×100
(5)重量平均分子量変化率の算出
保存安定性評価試験後のワニスの重量平均分子量を測定し、下記式によって変化率を算出した。
変化率(%)=(試験前の重量平均分子量-試験後の重量平均分子量)/試験前の重量平均分子量×100
(6-1)耐熱性樹脂膜の作製(実施例1~12、比較例1~11)
実施例で合成したワニスを1μmのフィルターを用いて加圧濾過し、異物を取り除いた。濾過したワニスを4インチシリコンウエハー上に塗布し、続いてホットプレート(大日本スクリーン製造株式会社製 D-Spin)を用いて、150℃で3分プリベークすることによりプリベーク膜を得た。膜厚は、キュア後に10μmとなるように調整した。プリベーク膜をイナートオーブン(光洋サーモシステム株式会社製 INH-21CD)を用いて窒素気流下(酸素濃度20pm以下)、350℃で30分熱処理し、耐熱性樹脂膜を作製した。続いてフッ酸に4分間浸漬して耐熱性樹脂膜を基板から剥離し、風乾した。
4インチシリコンウエハー上にワニスを塗布する代わりに、4インチシリコンウエハー上にアルミをスパッタしたものの上にワニスを塗布し、またフッ酸の代わりに塩酸に浸漬して基板から剥離した以外は(6-1)と同様にして、耐熱性樹脂膜を作製した。
熱機械分析装置(エスアイアイ・ナノテクノロジー株式会社製 EXSTAR6000 TMA/SS6000)を用いて、窒素気流下で測定を行った。昇温方法は、以下の条件にて行った。第1段階で150度まで昇温して試料の吸着水を除去し、第2段階で室温まで冷却した。第3段階で、昇温レート5℃/minで本測定を行い、ガラス転移温度を求めた。
ガラス転移温度の測定と同様にして測定を行い、50~200℃の線膨張係数の平均を求めた。
熱重量測定装置(株式会社島津製作所製 TGA-50)を用いて窒素気流下で測定を行った。昇温方法は、以下の条件にて行った。第1段階で150度まで昇温して試料の吸着水を除去し、第2段階で室温まで冷却した。第3段階で、昇温レート10℃/minで本測定を行い、5%熱重量減少温度を求めた。
