Description
両面銅張積層板(面積510mm×340mm、銅箔厚み12μm、基材厚み0.2mm、三菱ガス化学(株)製、商品名:CCL−E170)にドライフィルムレジスト(旭化成イーマテリアルズ(株)製、商品名:サンフォート(登録商標)AQ−4038、厚み40μm)を貼り付けた。次に、キャリアフィルムを剥離した後、表1記載の条件で処理工程と停止工程、その後、除去工程を行い、DFRの厚みが平均10μmまたは30μmとなるように、薄膜化処理を行った。なお、処理液の温度は25℃、除去液は炭酸ナトリウムを含んだpH=8の水溶液であり、除去液の温度は25℃、スプレー圧力は0.15MPa、除去液の流量は光架橋性樹脂層1cm2当たり0.3L/minであった。
薄膜化処理後、DFRの膜厚を40点で測定し、膜厚のばらつきを標準偏差σの値で評価した。なお、膜厚は、(株)スペクトラ・コープ製の小型高分解能分光装置(装置名:SolidLambdaUV−NIR)を用い、非接触、非破壊により測定し、反射率分光法から算出した。標準偏差σの値としては、標準偏差σの値が2.0μmより大きくなると、その後の露光工程、現像工程、エッチング工程に問題を発生し、製品として使用することができなくなるため、標準偏差σの値が2.0μm以下であることを本発明の評価基準とした。
