上記実施例により製造されたAl(CH3)2[CH3OC(CH3)2CH2NtBu]、Al(CH3)2[CH3OCH(CH3)CH2NtBu]およびAl(CH3)2[CH3OCH2CH2NtBu]前駆体化合物の物性の測定を実施した。物性としては、室温時の状態、沸点および自然発火性について測定した。
上記実施例により製造された実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])、実施例2(Al(CH3)2[CH3OCH(CH3)CH2NtBu])および実施例3(Al(CH3)2[CH3OCH2CH2NtBu])の前駆体化合物の熱重量分析(TG analysis)を実施した。
上記実施例により製造された実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])である前駆体化合物の原子層蒸着法(ALD)による成膜評価を進行させた。酸化剤としてはオゾン(O3)および水(H2O)を用い、不活性気体であるアルゴン(Ar)または窒素(N2)などをパージの目的で用いた。前駆体、アルゴン、オゾンまたは水、そしてアルゴンを注入することを1サイクルとし、蒸着はSi(シリコン)ウエハ上で行った。
<前駆体注入時間に応じた薄膜蒸着率の変化(Saturation)>
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体とオゾン(O3)の原子層蒸着(ALD)工程時、一定の薄膜蒸着率を示す前駆体化合物の注入時間を測定して自己制限的反応(Self−limiting reaction)を確認した。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体とオゾン(O3)の原子層蒸着(ALD)工程時、異なる温度による薄膜蒸着率を測定して工程温度区間(ALD window)を確認した。図3をみると、実施例1の前駆体は、150℃〜320℃まで一定の薄膜蒸着率を有する工程温度区間(ALD window)を有することが分かる。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体とオゾン(O3)の原子層蒸着(ALD)工程を進行させる時、工程温度に応じた元素含有量(Atomic%)および元素比率(Atomic ratio、O/Al)をXPS(X−ray photoelectron spectroscopy)分析により測定した。
<前駆体注入時間に応じた薄膜蒸着率の変化(Saturation)>
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体と水(H2O)の原子層蒸着(ALD)工程時、一定の薄膜蒸着率を示す前駆体化合物の注入時間を測定して自己制限的反応(Self−limiting reaction)を確認した。図5をみると、工程温度が150℃の時、比較例1の前駆体(TMA)の工程注入時間1秒後に一定の薄膜蒸着率を示す。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体と水(H2O)の原子層蒸着(ALD)工程時、異なる温度による薄膜蒸着率を測定して工程温度区間(ALD window)を確認した。図6をみると、実施例1の前駆体は、130℃〜320℃まで一定の薄膜蒸着率を示すが、比較例1の前駆体は、130℃〜200℃までは一定の薄膜蒸着率を示すのに対し、200℃〜320℃では薄膜蒸着率が低下する傾向を示した。表8および上述した説明により、比較例1の前駆体よりも、実施例1の前駆体がより広い工程温度区間(ALD window)を有することが分かる。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体と水(H2O)の原子層蒸着(ALD)工程を進行させる時、工程温度に応じた元素含有量(Atomic%)および元素比率(Atomic ratio、O/Al ratio)をXPS(X−ray photoelectron spectroscopy)分析により測定した。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体と水(H2O)の原子層蒸着(ALD)工程を進行させる時、蒸着工程回数(cycle)に応じた薄膜厚さの変化は150℃または300℃の温度条件で類似の傾向を有する。図8は、工程回数に応じた薄膜厚さの変化をグラフで示すものであり、温度条件150℃では0.91A/cycle、300℃では0.93A/cycleの薄膜蒸着率を有することが分かる。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体と水(H2O)の原子層蒸着(ALD)工程を進行させる時、工程温度に応じた薄膜の密度は、温度の増加に伴って密度も増加する傾向を示し、実施例1の前駆体が、比較例1の前駆体より優れた薄膜密度を有することが分かる。これは図9および表10を通して確認可能である。表10は、Al2O3(Bulk)の時の密度および比較例1の前駆体(TMA)と水(H2O)の原子層蒸着工程時、温度に応じた密度に関するものであって、文献Chem. Mater. 2004, 16, 639を参照した。
実施例1(Al(CH3)2[CH3OC(CH3)2CH2NtBu])の前駆体と水(H2O)の原子層蒸着(ALD)工程を進行させる時、温度に応じたホール(Hole)およびトレンチ(Trench)構造の段差被覆性に対してTEM(Transmission electron microscopy)測定により確認した。工程温度は150℃または300℃であり、ホール構造の時の縦横比は26:1であり、トレンチ構造の時の縦横比は40:1であった。
