Abstract
【解決手段】シリコン薄膜直上に形成される、Cu酸化物を含有する平面表示装置用Cu系配線膜。Cuの主結晶面(111)面のX線回折ピーク強度をCu(111)、Cu2Oの主結晶面(111)面のX線回折のピーク強度をCu2O(111)とした時に、ピーク強度比Cu(111)/Cu2O(111)の値が0.8〜2.5の範囲にあることを特徴とする。

Description
本発明の目的は、上記の課題に鑑み、基板との密着性を向上することが可能な新規なCu系配線膜を提供することである。
すなわち、本発明は、ガラス基板上に形成されるCu酸化物を有するCu系配線膜であって、Cuの主結晶面(111)面のX線回折ピーク強度をCu(111)、Cu2Oの主結晶面(111)面のX線回折のピーク強度をCu2O(111)とした場合に、その強度比Cu(111)/Cu2O(111)の値が0.8〜2.5の範囲にあるCu系配線膜である。
また、好ましくは、膜厚が200〜500nmである前記Cu系配線膜である。
また、好ましくは、比抵抗が15μΩcm以下の前記Cu系配線膜である。
また、前記Cu系配線膜上にCu膜が積層される構成も望ましい。
Cu系配線膜中のCu2O量に関しては、同定が困難であるため、X線回折強度測定において、Cuの主結晶面(111)面のピーク強度とCu2Oの主結晶面(111)面のピーク強度の比で特定している。ピーク強度比Cu(111)/Cu2O(111)は0.8〜2.5の範囲とすることで、密着性の向上の効果が十分現れる。好ましくは、ピーク強度比Cu(111)/Cu2O(111)が1.0〜2.0の範囲である。
なお、本発明のCu系配線膜においては、成膜時に比抵抗が高いものに関しても、成膜後に真空雰囲気中で加熱処理を行うことで、比抵抗を15μΩcm以下へ低減することが可能である。
また、試料1、5および6のX回折強度測定をした際のX線回折パターンをそれぞれ図1〜3に示す。
また、各試料を100Pa以下に減圧した真空雰囲気で温度250℃、1時間の加熱処理を行った後に、比抵抗を測定した。その結果も表1に示す。
また、試料4および5は、真空雰囲気中で加熱処理を行うことで、比抵抗を15μΩcm以下へ低減することが可能であることも分かる。
各試料は、比抵抗を測定するとともに、実施例1と同様に、X線回折強度測定を行いCuとCu2Oのピーク強度比を評価した。また、ガラス基板側からコニカミノルタ製のCM2002分光測色計でSi膜の反射率を測定した。
その後、各試料を100Pa以下に減圧した真空雰囲気で温度250℃、1時間の加熱処理を行った。加熱処理後の試料に関しても上記と同様に比抵抗、X線回折強度、反射率を測定した。以上の結果を表2に示す。
上記で作製した積層のCu系配線膜に関して、比抵抗を測定するとともに、密着性試験として積層のCu系配線膜に2mm間隔で碁盤の目状に切れ目を入れた後、膜表面にテープを貼り、引き剥がした時に基板上に残った桝目を面積率で評価する試験を行った。その結果、比抵抗は2.3μΩcm、密着性は100%であった。
以上から、積層のCu系配線膜とすることで、密着性と低抵抗特性を両立した配線膜が得られることが分かる。
