Abstract
Description
「金属光沢をもち,電気と熱をよく導き,固体状態では展性,延性に富む物質.水銀以外は室温ですべて固体である.ふつう種々の機械的加工を施すことができる.液化しても光学的・電気的性質は保たれることが多い.単体の金属結晶の大部分は面心立方,六方最密,体心立方のいずれかの構造をとり,通常は微結晶の集合体をなす.結晶中の原子は*金属結合によって結ばれ,電子の一部は自由電子として存在する.金属の性質は金属結合に由来する.単体アンチモン,ビスマスなど自由電子の数が少ない金属を*半金属とよぶ.単体に限らず2種以上の金属元素,または金属元素とある種の非金属元素(ホウ素,炭素など)を含む相にも金属性を示すものがある.なお,金属の電気伝導は温度の上昇とともに減少するが,非金属では増加するので,このことから両者を明確に区別することができる.」
金属としては特に限定されず、好ましい例としては、チタン、アルミニウム、銅、銀、金、白金、パラジウム、ニッケル、錫、コバルト、ロジウム、イリジウム、鉄、ルテニウム、オスミウム、マンガン、モリブデン、タングステン、ニオブ、タンタル、カルシウム、チタン、ビスマス、アンチモン、鉛、またはこれらの合金、から選ばれる少なくとも一種を挙げることができる。さらに好ましい金属としてはチタン、アルミニウムが挙げられる。

ジルコニウム化合物粒子Zr-4~Zr-6について、アルカリで溶融分解後、溶融物を塩酸で溶解し、超純水で定容して検液とした。ICP-AES(エスアイアイ・ナノテクノロジー(株)製、SPS5100型) により、検液中の元素の定量分析を行った結果を表1に示す。
各実施例および比較例により得られた着色膜について、X-Rite社製光学濃度計361TVisualを用いて、膜厚1μmあたりのOD値を算出した。
各実施例および比較例により得られた着色膜について、(株)島津製作所製紫外-可視分光光度計UV-2600を用いて、OD値が1.0となる膜厚における、波長365nmおよび550nmにおける透過率を測定した。波長365nmにおける透過率が高いほど、紫外領域における光透過性に優れる。また、波長550nmにおける光透過率に対する波長365nmにおける光透過率の比を算出した。
各実施例および比較例により得られた着色膜について、接触式膜厚計(“DEKTAK”(登録商標)150;アルバック社販売)を用いて、触針圧5mgでの表面粗度(nm)を測定した。
各実施例および比較例により得られた着色膜に、フォトマスクを介して、紫外線を200mJ/cm2を最大露光量として、10mJ/cm2ごとに露光量を下げて露光し、0.045重量%水酸化カリウム水溶液のアルカリ現像液でシャワー現像した後のパターン表面の荒れの有無を目視にて観察した。現像後のパターン表面に荒れが生じない最低露光量を感度とした。ただし、最大露光量においても現像後にパターンが残存していない場合は「欠落」とした。
各実施例および比較例により得られた着色膜に、パターン幅の異なる、ライン・アンド・スペースパターンが1対1の間隔で配置されたフォトマスクを介して、紫外線を200mJ/cm2露光し、所定のアルカリ現像液でシャワー現像した後に、パターンを顕微鏡にて観察した。現像後のパターンが解像している最小の線幅を最小解像度とした。
各実施例および比較例により得られた着色膜に、線幅20μm、間隔1対1のライン・アンド・スペースパターンが配置されたフォトマスクを介して200mJ/cm2を最大露光量として、10mJ/cm2ごとに露光量を下げて露光し、所定のアルカリ現像液でシャワー現像した後に、パターンおよびスペースの線幅を顕微鏡にて観察した。ライン・アンド・スペースパターンを1対1で形勢できる最低露光量を感度とした。ただし、最大露光量においても現像後にスペースパターン部に未溶解物が残存している場合は「残渣」とした。
各実施例および比較例により得られた遮光パターンについて、プロピレングリコールモノメチルエーテルアセテート(以下、「PGMEA」と記載する)に浸した不織布で15秒間表面をふき取った後のOD値を、前述の[遮光性]と同様に測定した。ふき取り後のOD値がふき取り前のOD値(4.0)に近いほど、耐溶剤性に優れる。
