本発明の感光性樹脂組成物を直接基板に塗布する場合には、基板としてはシリコン、セラミックス類、ガリウムヒ素などのウエハ、または、その上に金属が電極、配線として形成されているものが用いられるが、これらに限定されない。塗布方法としてはスピンナを用いた回転塗布、スプレー塗布、ロールコーティングなどの方法がある。また、塗布膜厚は、塗布手法、組成物の固形分濃度、粘度などによって異なるが、通常、乾燥後の膜厚が0.1~150μmになるように塗布される。 シリコンウエハなどの基板と感光性樹脂組成物との接着性を高めるために、基板を前述のシランカップリング剤で前処理することもできる。例えば、シランカップリング剤をイソプロパノール、エタノール、メタノール、水、テトラヒドロフラン、プロピレングリコールモノメチルエーテルアセテート、プロピレングリコールモノメチルエーテル、乳酸エチル、アジピン酸ジエチルなどの溶媒に0.5~20質量%溶解させた溶液を、スピンコート、浸漬、スプレー塗布、蒸気処理などにより表面処理をする。場合によっては、その後50~300℃の熱処理を行い、基板とシランカップリング剤との反応を進行させる。
(C)化合物にて重合した(A)成分0.03gと、内部標準物質として3-ニトロ安息香酸メチル0.01gを重水素化されたジメチルスルホキシド0.7gに溶解させ、NMR(日本電子(株)製、GX-270)により分析した。3-ニトロ安息香酸メチル由来の3.9ppm付近のピークの面積を基準とし、各々のピーク面積から(A)成分が含有している(C)化合物の量を定量した。
塗布現像装置Mark-7(東京エレクトロン(株)製)を用いて、8インチシリコンウェハー上にスピンコート法でワニスの塗布を行い、120℃で3分間ホットプレートにてベークをして膜厚3.2μmのプリベーク膜を作製した。その後、前記Mark-7の現像装置を用いて、2.38質量部のテトラメチルアンモニウム水溶液(以下2.38%TMAH、多摩化学工業(株)製)を用いて現像した後、蒸留水でリンス後、振り切り乾燥し、現像後ベタ膜を窒素雰囲気下、200℃にて60分間キュアし、硬化膜を得た。
プリベーク後、大日本スクリーン製造(株)製ラムダエースSTM-602を使用し、ポリイミドを基準とし、プリベーク後の膜は屈折率1.629として、キュア後の膜は屈折率1.773として測定した。
次の方法にて金属材料との密着性試験を行なった。
シリコンウエハ上に銅をスパッタリングし、それぞれ200nmの厚みで形成された金属材料層を表面に有する基板(銅スパッタ基板)を用意した。この基板上にワニスをスピンナ(ミカサ(株)製)を用いてスピンコート法で塗布し、次いでホットプレート(大日本スクリーン製造(株)製D-SPIN)を用いて120℃で3分ベークし、最終的に厚さ8μmのプリベーク膜を作製した。ネガ型の感光性樹脂組成物についてはこの後露光機i線ステッパーNSR-2005i9C(ニコン社製)を用いて1000mJ/cm2の露光量にて基板全面を露光した。これらの膜をクリーンオーブン(光洋サーモシステム(株)製CLH-21CD-S)を用いて、窒素気流下(酸素濃度20ppm以下)、140℃で30分、次いでさらに昇温して200℃にて1時間キュアし、感光性樹脂硬化膜を得た。
基板を2分割し、それぞれの基板についてキュア後の膜に片刃を使用して2mm間隔で10行10列の碁盤目状の切り込みをいれた。このうち一方のサンプル基板を用い、セロハンテープによる引き剥がしによって100マスのうち何マス剥がれたかを計数し、金属材料/樹脂硬化膜間の密着特性の評価を行なった。また、もう一方のサンプル基板については、プレッシャークッカーテスト(PCT)装置(タバイエスペエック(株)製HAST CHAMBER EHS-211MD)を用いて121℃、2気圧の飽和条件で400時間PCT処理を行なった後、上記の引き剥がしテストを行なった。いずれの基板についても引き剥がしテストで剥がれ個数が10未満をA、10以上20未満をB、20以上をCとした。
段差付き基板上にワニスを回転塗布し、次いで、120℃のホットプレート(東京エレクトロン(株)製の塗布現像装置Act-8使用)で3分間ベークし、平均厚さ10μmのプリベーク膜を作製した。プリベーク膜にナトリウムランプ照射し、目視にて表面観察を行った。縦スジがないものを○、縦スジが発生したものを×とした。次いで上記プリベーク膜の、基板の段差部および埋め込み部の上部を覆う膜の厚さを、電界放出形走査電子顕微鏡(株式会社日立ハイテクノロジーズ製S-4800)を用いて基板段差部の断面を観察して測定した。測定箇所は、基板外周から各辺10mmずつ除外した残りの部分を30分割し、30箇所とした。段差埋め込み性は次の式により算出した。
最大高さ=基板上の段差の高さとその上を覆うプリベーク膜の膜厚の合計の平均値
埋め込み部膜厚=埋め込み部の中央の膜厚の平均値
段差埋め込み性(%)=[最大高さ/埋め込み部膜厚]×100
ここで、段差埋め込み性は、90~100%が好ましく、95~100%がさらに好ましい。段差埋め込み性は、95%以上100%以下の場合をA、90以上95%未満の場合をB、90%未満の場合をCとして評価とした。
