さらに(C)カチオン重合開始剤を含有することを特徴とする樹脂組成物。
(A)高分子化合物は、その分子鎖末端がカルボン酸残基に由来する構造であることが好ましい。前記(A)高分子化合物の分子鎖末端がカルボン酸残基に由来する構造であることによって、分子鎖末端が、カチオン重合の阻害官能基となり得る、アミン末端構造を保有しない分子構造とすることができ、結果として、ポリアミドやポアイミドおよびポリアミドイミドを用いた際においても、十分なカチオン重合性を発現することができる点で好ましい。
一般式(1)および(2)中のY1およびY2は2価~4価の有機基を示し、ジアミン由来の有機基を表している。
(A)高分子化合物が前記一般式(3)または(4)で表される化合物に由来する構造を有することで、樹脂骨格が屈曲性を有することで、硬化前の樹脂組成物として、有機溶剤への溶解性が高く、組成物中において樹脂の析出が発生し難く、保存安定性に優れる点から好ましい。
分子鎖末端がカルボン酸残基に由来する構造である(A)高分子化合物は、例えば分子鎖末端がカルボン酸残基であるポリイミドの場合には、重合の際に用いるジアミンに対して酸無水物の含有量を多くすることで得ることができる。その際、(A)高分子化合物のカルボン酸残基の合計を100モル%とした場合、アミン残基の合計は60モル%以上98モル%以下であることが好ましい。つまり(A)高分子化合物は、カルボン酸残基の合計を100モル%とした場合に、アミン残基の合計を60~98モル%として重合させて得られる化合物であることが好ましい。アミン残基の合計が60モル%以上であると、重量平均分子量が1,000以上となり易く、フィルム状にする際の製膜性に優れ、98モル%以下であると末端がアミン残基となる高分子化合物が含有される割合が小さくなり、カチオン重合反応が進行し易くなり、硬化膜の耐薬品性が向上する。
本発明において、(A)高分子化合物は、たとえば、次の方法により合成されるが、これに限定はされない。ポリイミド構造は、ジアミンの一部を末端封止剤である1級モノアミンに置き換えて、または、テトラカルボン酸二無水物を、末端封止剤であるジカルボン酸無水物に置き換えて、公知の方法で合成される。例えば、低温中でテトラカルボン酸二無水物とジアミン化合物とモノアミンを反応させる方法、低温中でテトラカルボン酸二無水物とジカルボン酸無水物とジアミン化合物を反応させる方法、テトラカルボン酸二無水物とアルコールとによりジエステルを得、その後ジアミンとモノアミンと縮合剤の存在下で反応させる方法などの方法を利用して、ポリイミド前駆体を得る。その後、公知のイミド化反応法を利用してポリイミドを合成することができる。

本発明において、(C)カチオン重合開始剤は、光カチオン重合開始剤であることが好ましい。(C)カチオン重合開始剤として光カチオン重合開始剤を選択することにより、光照射部と光未照射部でカチオン重合の進行のコントラストをつけることができ、任意の現像液で樹脂組成物を溶解させることで、パターン形成が可能となる点から好ましい。
本発明の樹脂組成物は、紫外線を吸収し、吸収した光エネルギーを光酸発生剤に供与するために増感剤を使用してもよい。増感剤としては、例えば9位と10位にアルコキシ基を有するアントラセン化合物(9,10-ジアルコキシ-アントラセン誘導体)が好ましい。アルコキシ基としては、例えばメトキシ基、エトキシ基、プロポキシ基等のC1~C4のアルコキシ基が挙げられる。9,10-ジアルコキシ-アントラセン誘導体は、さらに置換基を有していても良い。置換基としては、例えばフッ素原子、塩素原子、臭素原子、ヨウ素原子等のハロゲン原子、メチル基、エチル基、プロピル基等のC1~C4のアルキル基やスルホン酸アルキルエステル基、カルボン酸アルキルエステル基等が挙げられる。スルホン酸アルキルエステル基やカルボン酸アルキルエステルにおけるアルキルとしては、例えばメチル、エチル、プロピル等のC1~C4のアルキルが挙げられる。これらの置換基の置換位置は2位が好ましい。
本発明の樹脂組成物は、硬化前の形状は限定されず、例えば、ワニス状やフィルム状などが挙げられる。本発明の樹脂組成物フィルムは、本発明の樹脂組成物の形態をフィルム状としたもの、つまり、本発明の樹脂組成物から形成された樹脂組成物被膜を有する樹脂組成物フィルムである。そのため本発明の樹脂組成物フィルムは、支持体上に形成されたフィルム状、つまり支持体上に本発明の樹脂組成物から形成された樹脂組成物被膜を有する樹脂組成物フィルムであってもよいし、支持体のない態様であってもよい。ワニス状で用いる場合は、(A)~(C)成分および必要に応じ加えられる成分を有機溶媒に溶解させたものを用いることができる。また、樹脂組成物フィルムは、例えば本発明の樹脂組成物を支持体上に塗布し、次いでこれを必要により乾燥することにより得られる。

次に、本発明の樹脂組成物ワニス、またはそれを用いた樹脂組成物フィルムをパターン加工する方法、および他の部材に熱圧着する方法について、例を挙げて説明する。
本発明の硬化膜は、本発明の樹脂組成物または本発明の樹脂組成物フィルムの樹脂組成物被膜を硬化した硬化膜である。本発明の樹脂組成物や樹脂組成物フィルムの樹脂組成物被膜を硬化した本発明の硬化膜は、半導体装置等の電子部品に使用することができる。本発明でいう半導体装置とは、半導体素子の特性を利用することで機能し得る装置全般を指す。半導体素子を基板に接続した電気光学装置や半導体回路基板、複数の半導体素子を積層したもの、並びにこれらを含む電子装置は、全て半導体装置に含まれる。また、半導体素子を接続するための多層配線板等の電子部品も半導体装置に含める。具体的には、半導体のパッシベーション膜、半導体素子の表面保護膜、半導体素子と配線の間の層間絶縁膜、複数の半導体素子の間の層間絶縁膜、高密度実装用多層配線の配線層間の層間絶縁膜、有機電界発光素子の絶縁層などの用途に好適に用いられるが、これに制限されず、様々な用途に用いることができる。
本発明の樹脂組成物フィルムは、樹脂組成物被膜を200℃で加熱した時の重量減少率が0.01%以上、1.0%以下であることが好ましい。該重量減少率が上記範囲であることによって、上記中空構造体の屋根部分として硬化膜を形成する際に、樹脂組成物被膜からのアウトガス成分が抑えられ、極端に屋根構造が膨らんだり、または硬化収縮により撓んだりすることを抑制することができる。
なお、200℃で加熱した時の重量減少率は、熱重量分析装置を用い、樹脂組成物被膜の質量を8~12mg秤量し、窒素ガスを100mL/分でパージした状態で、40℃で10分間保持した後の重量を基準とし、40℃から200℃へ10℃/分の昇温速度で昇温し、その後60分間保持した後の質量の減少率を算出することができる。
また、本発明の樹脂組成物フィルムは、樹脂組成物被膜の40℃での溶融粘度が、0.5×106MPa・s以上、1.0×107MPa・s以下であることが好ましい。樹脂組成物フィルムの樹脂組成物被膜の40℃での溶融粘度が、0.5×106MPa・s以上であると室温でのフィルム表面のタックが低減され、フィルムのハンドリングが容易になる。一方、樹脂組成物フィルムの樹脂組成物被膜の40℃での溶融粘度が、1.0×107MPa・s以下であると、室温でのフィルムのクラックが低減され、フィルムの欠点が低減し、歩留まりが向上する。
本発明の樹脂組成物は、前記の通り、中構造体の屋根部分として使用することができる。特に、屋根部分として使用される際、樹脂組成物フィルムの樹脂組成物被膜を熱硬化させた後での180℃でのクリープ変形量が、0.5%以上、2.5%以下であることが好ましい。クリープ変形量が、0.5%以上であると硬化膜の靭性が高く、本発明の硬化膜を中空構造の屋根構造として有する電子部品をモールド樹脂で封止した際に、屋根構造にクラックが発生することが抑えられ、電子部品の収率が向上する。一方、クリープ変形量が2.5%以下であると、モールド樹脂で封止した際に、モールド封止時の圧力で屋根構造の撓みが抑制され、中空構造部分を保持したままでの、モールド封止された電子部品の収率を向上することができる。
各実施例および比較例で作製した樹脂組成物フィルムの保護フィルムを剥離し、該剥離面を、4インチのシリコンウェハ上に、真空ダイアフラム式ラミネータ((株)名機製作所製、MVLP-500/600)を用いて、上下熱盤温度80℃、真空引き時間20秒、真空プレス時間30秒、貼付圧力0.5MPaの条件でラミネートし、シリコンウェハ上に樹脂組成物フィルムを形成した。そして、支持体フィルムを剥離した後、露光装置にビアサイズが30μmφ、20μmφ、10μmφのパターンを有するマスクをセットし、マスクと感光性樹脂組成物フィルムの露光ギャップ100μmの条件下で、超高圧水銀灯を用いて、露光量1000mJ/cm2(i線換算、全波長露光)で露光を行った。露光後、ホットプレートで120℃、10分間、露光後加熱を行った。その後、ディップ現像にて、水酸化テトラメチルアンモニウムの2.38質量%水溶液を用いて未露光部を除去し、水にてリンス処理をした。現像時間は、未露光部が完全に溶解した時間の2倍の時間とした。この様にして得られたパターンを、光学顕微鏡で観察し、パターンにツマリ等の異常のない場合の最小のサイズをパターン加工性の評価とした。また、パターンが全て溶解したものを0(不良)とした。
<ガラス転移温度の評価>
前記パターン加工性の評価方法と同様にして、基板をシリコンウェハから平面サイズが10cm×10cmの銅箔(CF-T9DA-SV-1、福田金属箔粉工業(株)製)に変更し、銅箔上に樹脂組成物フィルムを形成した。そして支持体フィルムを剥離した後、超高圧水銀灯を用いて、露光量1000mJ/cm2(i線換算、全波長露光)で露光を行った。露光後、ホットプレートで120℃、10分間、露光後加熱を行った。そして、イナートオーブン(光洋サーモシステム(株)製、INL-60)を用いて、N2雰囲気下(酸素濃度20ppm以下)、室温から200℃まで60分かけて昇温したのち、200℃で60分間熱処理し、銅箔上に形成された樹脂組成物フィルムの硬化膜を得た。
<引張強度・引張伸度の評価>
前記ガラス転移温度の評価方法と同様にして、樹脂組成物フィルム単体の硬化膜を得た。得られた硬化膜を10mm×80mmサイズの試験片にカットし、万能試験機AG-Xplus((株)島津製作所製)、50Nのロードセルを用いて、室温下、チャック間距離50mm、引張速度50mm/分で引張試験を行い、引張強度(破断点応力)および引張伸度(破断点伸度)の測定を行った。測定は1検体につき10枚の試験片について行い、結果から上位5点の平均値を求めた。また、上記パターン加工性の評価でパターンが溶解したものの引張強度・引張伸度の評価は実施せず、0(不良)とした。
