シリコンウエハ上に、各着色硬化性組成物をスピンコータを用いて塗布し、次いで、ホットプレートを用いて、100℃、120秒間の加熱(プリベーク)を行い、膜厚が1.0μmの塗膜を得た。
次いで、i線ステッパー露光装置FPA-3000iS+(キヤノン(株)製)を使用して、0.8μmの市松模様のパターンが刻まれているマスクを介して、50~1000mJ/cm2の範囲の露光量を、10mJ/cm2の刻みで変化させて照射した(露光工程)。次いで、テトラメチルアンモニウムハイドロオキサイド(TMAH)0.3%水溶液を用いて、23℃にて60秒間パドル現像を行い、その後、純水を用いて20秒スピンシャワーにて、リンスを行い、更に純水にて水洗を行った。その後、パターン表面に付着した水滴をエアーで除去し、パターンを自然乾燥させて、パターンを得た。
感度の評価は、上記の露光工程において光が照射された領域の現像後の膜厚が、露光前の膜厚100%に対して95%以上であった時の最少の露光量(最適露光量)を測定し、これを感度として評価した。上述の最少の露光量(最適露光量)の値が小さいほど感度が高いことを示す。
-評価基準-
A:50mJ/cm2未満
B:50mJ/cm2以上100mJ/cm2未満
C:100mJ/cm2以上200mJ/cm2未満
D:200mJ/cm2以上300mJ/cm2未満
E:300mJ/cm2以上
シリコンウエハ上に、各着色硬化性組成物をスピンコータを用いて塗布し、次いで、ホットプレートを用いて、100℃、120秒間の加熱(プリベーク)を行い、膜厚が1.0μmの塗膜を得た。
次いで、i線ステッパー露光装置FPA-3000iS+(キヤノン(株)製)を使用して、0.8μmの市松模様のパターンが刻まれているマスクを介して、400mJ/cm2の露光量で露光した。次いで、テトラメチルアンモニウムハイドロオキサイド(TMAH)0.3%水溶液を用いて、23℃にて60秒間パドル現像を行い、その後、純水を用いて20秒スピンシャワーにて、リンスを行い、更に純水にて水洗を行った。その後、パターン表面に付着した水滴をエアーで除去し、パターンを自然乾燥させて、パターンを得た。
パターンが形成されたシリコンウエハをSEM(Scanning Electron Microscope、倍率:20,000倍)にて観察し、SEM写真から100マス中のパターン欠損しているマスの比率を観察して、密着性を評価した。評価基準は以下の通りである。
-評価基準-
A:パターン欠損している比率が0%
B:パターン欠損している比率が0%を超え10%以下
C:パターン欠損している比率が10%を超え20%以下
D:パターン欠損している比率が20%を超え50%以下
E:パターン欠損している比率が50%を超える
上記密着性の評価と同様の手順でパターンを形成した。得られたパターンの断面形状をSEM(Scanning Electron Microscope、倍率:20,000倍)にて観察し、SEM写真から5個のパターンを抽出し、5個のパターンの断面の平均傾きを求めて以下の基準でパターン断面形状1を評価した。なお、パターンの断面の傾きは、パターンを形成した部分におけるシリコンウエハ上のパターンの厚み方向における傾きのことである。具体的には、シリコンウエハの表面とパターンの厚み方向の辺とで構成される部分の角度を測定した。パターンの傾きがシリコンウエハの表面に対して90度を超える場合とは、パターンは、シリコンウエハ側からパターンの表面側に向かって面積が大きくなる、すなわちパターン底面にエッジが入っており好ましくないことを意味する。
-評価基準-
A:角度が80度を超え90度以下
B:角度が90度を超え100度以下
C:角度が100度を超え110度以下
D:角度が110度を超え150度以下
E:角度が150度を超える
上記で得られた各着色硬化性組成物を100g、ポリ容器に入れて密封し、0℃3ヶ月保存した後、室温(25℃)に戻し、析出物の有無を確認した。保存後の着色硬化性組成物をろ紙(ADVANTEC No.4A、アドバンテック東洋(株)製)を使用してろ過し、ろ過した後のろ紙に残った析出物の重さを秤量した。
-評価基準-
A:析出物が全く確認されなかった。
B:析出物が0.1g未満だった。
C:析出物が0.1g以上0.5g未満だった。
D:析出物が0.5g以上1.0g未満だった。
E:析出物が1.0g以上だった。
また、上記表6~表9に示すように、実施例の着色硬化性組成物は、感度、密着性、アンダーカット抑制性、及び、溶解性にも優れる。
