Description
上記のポリマーを除き、ここに示す種々の製剤を製造するために使用されるコポリマー/ターポリマーおよび組成の識別は、表1に示す。露光された光フォトレジスト中の架橋密度を増加させるために、置換ポリマー例に、側鎖にメタクリレートを伴う2つのアクリルテトラポリマー(バインダー1およびバインダー2、Miwon Commercial Co.,Ltd製)を使用した。Joncryl 817, 819、および821 ポリマー(ポリアクリレートポリマー、S. C. Johnson, Inc製)ならびに、poly GK(ヒドロキシスチレン/t−ブチルメタクリレートのコポリマー=65/35、DuPont製)樹脂を進行速度を調整するために使用した。一つもしくは二つ以上のジ官能性、トリ官能性、テトラ官能性およびペンタ官能性メタクリレートおよびアクリレートを、架橋密度を調整するために使用した。一つもしくは二つ以上の光開始剤および阻害剤を、光速度(photospeed)を調整するために使用した。
36.06gの上記ポリマー例6により製造されたポリマーを、22.10gのプロピレングリコールモノメチルエーテルアセテート、14.43gのSR268、および21.64gのDHDMAと混合した。1晩回転させた後、3.61gのIrgacure(登録商標) 907および1.80gのIrgacure(登録商標)819を混合した。0.01gのMegafac(登録商標)R08および0.26gのLignostab(登録商標)1198阻害剤を混合し、そして混合物を2日間回転させた。組成物を濾過し、シリコンウエハ上にスピンコートし、ホットプレート上で5分間、140℃で乾燥させた。乾燥させたコーティングを測定したところ40ミクロンの厚さであった。フォトレジストコーティングを600mJ/cm2で露光した。露光されたコーティングを、スピンコーター上で、0.26Nテトラメチル水酸化アンモニウムを使用して現像させた。得られたネガ型レリーフは、滑らかな側壁、四角に区切られた頂部を有し、アンダーカットの痕跡はなかった。
上記ポリマー例5により製造されたポリマーを使用して、組成物例1を繰り返した。現像が速かったことを除き、組成物例1の工程を繰り返し同様の結果が得られた。
各々、上記ポリマー例3およびにポリマー例4より製造されたポリマーを使用して、組成物例1を繰り返した。組成物例1の工程を繰り返し、現像されたコーティングを作成した。ポリマー例3を含む組成物が、ポリマー例4よりも長い現像時間によりパターンを形成した。
