本発明のポジ型感光性樹脂組成物は、(a)成分として、ポリオキサゾール前駆体の構造を有するアルカリ水溶液可溶性のポリアミドを含む。本発明に用いられるポリアミドは、ポリオキサゾール前駆体の構造を一部に有し、全体としてアルカリ水溶液可溶性であれば特に制限はなく、例えば、ポリオキサゾール前駆体ではないポリアミドの構造、ポリベンゾオキサゾールの構造、ポリイミドやポリイミド前駆体(ポリアミド酸やポリアミド酸エステル)の構造等をポリオキサゾール前駆体の構造と共に有していても良い。
ジアミン(i)及びテトラカルボン酸二無水物(ii)としては次のものが挙げられる。
合成例1 ポリベンゾオキサゾール前駆体の合成
攪拌機、温度計を備えた0.5リットルのフラスコ中に、4,4'−ジフェニルエーテルジカルボン酸15.48gと、N−メチルピロリドン90gとを仕込み、フラスコを5℃に冷却した後、塩化チオニル12.64gを滴下し、30分間反応させて、4,4'−ジフェニルエーテルジカルボン酸クロリドの溶液を得た。次いで、攪拌機、温度計を備えた0.5リットルのフラスコ中に、N−メチルピロリドン87.5gを仕込み、ビス(3−アミノ−4−ヒドロキシフェニル)ヘキサフルオロプロパン18.30gを添加し、攪拌溶解した。次いで、ピリジン8.53gを添加し、温度を0〜5℃に保ちながら、4,4'−ジフェニルエーテルジカルボン酸クロリドの溶液を30分間で滴下した後、30分間攪拌を続けた。得られた溶液を3リットルの水に投入し、析出物を回収、純水で3回洗浄した後、減圧乾燥してポリヒドロキシアミド(ポリベンゾオキサゾール前駆体)を得た(以下、ポリマーIとする)。ポリマーIのGPC法標準ポリスチレン換算により求めた重量平均分子量は14580、分散度は1.6であった。
合成例1で使用した4,4'−ジフェニルエーテルジカルボン酸の20mol%をシクロヘキサン−1,4−ジカルボン酸に置き換えた以外は合成例1と同様の条件にて合成を行った。得られたポリヒドロキシアミド(以下、ポリマーIIとする)の標準ポリスチレン換算により求めた重量平均分子量は18580、分散度は1.5であった。
上記ポリベンゾオキサゾール前駆体100重量部[(a)成分]に対し、感光剤である成分(b)、加熱により酸を発生する熱潜在酸発生剤(c)、フェノール性水酸基を有する化合物(d)、溶剤(e)を下記表1に示した所定量にて配合し、さらに接着助剤として尿素プロピルトリエトキシシランの50%メタノール溶液10重量部を配合した。この溶液を3μm孔のテフロン(登録商標)フィルタを用いて加圧ろ過して、感光性樹脂組成物の溶液を得た。
さらに、表1に示した実施例1、2、3、4、5、6、参考例4、5で用いた材料からなるポジ型感光性樹脂組成物溶液に関して、硬化方法を変えた検討を行った。まず、これらのポジ型感光性樹脂組成物溶液をシリコンウエハ上にスピンコートして、120℃で3分間加熱し、膜厚15μmの塗膜を形成した。その後、上記塗膜をラムダテクノロジー社製Microcure2100により、マイクロ波出力450W、マイクロ波周波数5.9〜7.0GHzとし、基板温度を200℃に保って、2時間硬化し、膜厚約10μmの硬化膜を得た。
実施例1と同様に合成例で合成したポリベンゾオキサゾール前駆体100重量部[(a)成分]に対し、感光剤である成分(b)、成分(c)、フェノール性水酸基を有する化合物(d)、溶剤(e)を下記表5に示した所定量にて配合し、さらに接着助剤として尿素プロピルトリエトキシシランの50%メタノール溶液10重量部を配合した。なお、ここでは、成分(c)に関しては添加しないか、あるいは以下に示すC15〜C19を用いた。上記溶液を3μm孔のテフロン(登録商標)フィルタを用いて加圧ろ過して、感光性樹脂組成物の溶液を得た。
合成例3 ヒドロキシ基含有ジアミン化合物(VII)の合成
乾燥窒素気流下、ビス(3−アミノ−4−ヒドロキシフェニル)ヘキサフルオロプロパン18.3g(0.05mol)をアセトン100ml、プロピレンオキシド17.4g(0.3mol)に溶解させ、−15℃に冷却した。ここに4−ニトロベンゾイルクロリド20.4g(0.11mol)をアセトン100mlに溶解させた溶液を滴下した。滴下終了後、−15℃で4時間反応させ、その後室温に戻した。析出した白色固体をろ別し、50℃で真空乾燥した。次に得られた固体30gを300mlのステンレスオートクレーブに入れ、メチルセルソルブ250mlに分散させ、5%パラジウム−カーボンを2g加えた。ここに水素を導入して、還元反応を室温で行った。約2時間反応後、ろ過して触媒であるパラジウム化合物を除き、ロータリーエバポレーターで濃縮し、ジアミン化合物(VII)を得た。得られた固体をそのまま反応に使用した。
乾燥窒素気流下、ビス(3−アミノ−4−ヒドロキシフェニル)ヘキサフルオロプロパン18.3g(0.05mol)とアリルグリシジルエーテル34.2g(0.3mol)をγ−ブチロラクトン100gに溶解させ、−15℃に冷却した。ここにγ−ブチロラクトンに溶解させた無水トリメリット酸クロリド22.1g(0.11mol)を反応液の温度が0℃を超えないように滴下した。滴下終了後、0℃で4時間反応させた。この溶液をロータリーエバポレーターで濃縮して、トルエン1lに投入して酸無水物(VIII)を得た。
乾燥窒素気流下、合成例3で得られたヒドロキシル基含有ジアミン(VII)15.1g(0.025mol)をN−メチル−2−ピロリドン50gに溶解させた。ここに合成例4で得られたヒドロキシ基含有酸無水物(VIII)17.5g(0.025mol)をピリジン30gとともに加えて、60℃で6時間反応させた。反応終了後、溶液を水2lに投入してポリマー固体の沈殿をろ過により集めた後、水洗、減圧乾燥して、ポリ(イミドーベンゾオキサゾール)前駆体を得た(以下、ポリマーIIIとする)。
合成例5で使用したヒドロキシル基含有ジアミン(VII)を4,4’−ジアミノフェニルエーテル5.01g(0.025mol)に置き換えた以外は、合成例5と同様の条件にて合成を行い、ポリ(イミドーベンゾオキサゾール)前駆体を得た(以下、ポリマーIVとする)。
