波長650nm以上、950nm以下の光のうち、一の波長を有する光に対する配線層5の反射率R1と、上記した一の波長を有する光に対する異反射率層3の反射率R2との差(|R1−R2|)は、40%以上である。
金属支持層2の材料は、特に限定されない。金属支持層2の材料としては、例えば、公知ないし慣用の金属系材料(具体的には、金属材料)から適宜選択して用いることができる。具体的には、金属系材料としては、周期表で、第1族〜第16族に分類されている金属元素や、これらの金属元素を2種類以上含む合金などが挙げられる。なお、金属系材料としては、遷移金属、典型金属のいずれであってもよい。より具体的には、金属系材料としては、例えば、カルシウムなどの第2族金属元素、チタン、ジルコニウムなどの第4族金属元素、バナジウムなどの第5族金属元素、クロム、モリブデン、タングステンなどの第6族金属元素、マンガンなどの第7族金属元素、鉄などの第8族金属元素、コバルトなどの第9族金属元素、ニッケル、白金などの第10族金属元素、銅、銀、金などの第11族金属元素、亜鉛などの第12族金属元素、アルミニウム、ガリウムなどの第13族金属元素、ゲルマニウム、錫などの第14族金属元素が挙げられる。これらは、単独使用または併用することができる。
<第2工程>
第2工程では、配線層5の外形形状を検査する。
厚みが100μm、材料が銅合金(銅−チタン合金)である金属支持層2を準備した。波長650nmの光に対する金属支持層2の反射率R3は、81.1%であった。
層構成、各層の物性および第2工程で用いられる波長を表1〜3に従って変更した以外は、実施例1と同様にして、第1工程および第2工程を実施した。
第2工程における配線10の検査について、下記の通り評価した。
○:反射光12における強いコントラストに基づき、配線10の外形形状を明瞭に認識できた。
×:反射光12におけるコントラストが弱く、そのため、配線10の外形形状を明瞭に認識できなかった。
