Description
実施例1.様々な温度でのPEALDによるケイ酸ジルコニウム膜の調製
シャワーヘッド型ALD反応器(大韓民国、Quros社製)内で典型的なケイ酸ジルコニウム膜を堆積させた。ウエハーの温度は比例・積分・微分(PID)制御器を用いて制御した。1〜50Ω・cmの抵抗率を有し、ホウ素をドープしたp型(100)ウエハー(大韓民国、LG Siltron社製)であるケイ素ウエハー上にこの膜を堆積させた。この堆積に使われた金属アミド前駆体は、BK500UST型温度制御バブラー(ペンシルバニア州、アレンタウン、エア プロダクツ アンド ケミカルズ社製)内で保管されていて、キャリアガスとしてアルゴンを用いて供給されるテトラキス(エチルメチルアミノ)ジルコニウム(TEMAZ)であった。この堆積に使われたケイ素含有前駆体は、BK1200USH型温度制御バブラー(ペンシルバニア州、アレンタウン、エア プロダクツ アンド ケミカルズ社製)内で保管されていて、キャリアガスとしてアルゴンを用いて供給されたビス(tert‐ブチルアミノ)シラン(BTBAS)であった。酸素源は、100sccmのO2流量及び50Wの無線電力の条件で無線周波発生器を用いて発火させた酸素プラズマであった。反応器の圧力は約1Torrであり、無線電力は各ALDサイクルの初めから終わりまで一定に保った。堆積は、200℃、250℃、300℃、及び350℃の各温度に抵抗加熱した接地電極に固定したSiウエハー上で起きた。500標準立方センチメートル(sccm)の流量のアルゴンの連続流(前駆体側で250sccmであり、酸素源側では250sccmであった)を全堆積の初めから終わりまで流した。典型的なALDサイクルは、25sccmの流量でArキャリアガスによりバブリングされたケイ素含有前駆体BTBASを0.5秒間、Arパージを5秒間、RFプラズマ発生中に100sccmの流量の酸素プラズマを5秒間、Arパージガスを5秒間、25sccmの流量でArキャリアガスによりバブリングされた金属アミド前駆体TEMAZを3秒間、Arパージを5秒間、及びRFプラズマ発生中に100sccmの流量の酸素プラズマガスを5秒間、及びArパージを5秒間、逐次供給する工程からなっていた。処理室又は反応器の圧力は約1.0Torrだった。各々の典型的な膜ごとに200℃、250℃、300℃、350℃の異なるウエハー温度でこのサイクルを約200回繰り返した。
ヒーター温度が250℃であることを除けば、実施例1で説明したものと同様の方法で3つの典型的な膜を堆積させた。ウエハー温度は200℃、250℃、300℃、及び350℃である。ウエハー温度とヒーター温度との温度差は、ヒーター温度によって変化した。
次の態様で酸化ジルコニウム及び酸化ケイ素を含むナノ積層膜を調製できる。処理室の圧力は約1.0Torrである。第一に、TEMAZを、流量25sccmのArキャリアガスで3秒間、流量500sccmのArパージガスで5秒間、RFプラズマ発生中に流量100sccmの酸素プラズマガスで5秒間、及び流量500sccmのArパージガスで5秒間バブリングするというサイクルで、200サイクルのZrO2を堆積させる。第二に、BTBASを、流量25sccmのArキャリアガスで0.5秒間、流量500sccmのArパージガスで5秒間、REプラズマ発生中の流量100sccmの酸素プラズマで5秒間、流量500sccmのArパージガスで5秒間バブリングするというサイクルで、50サイクルのSiO2を堆積させる。その後、別の200サイクルのZrO2を堆積させて、酸化ジルコニウム/酸化ケイ素/酸化ジルコニウムのナノ積層膜を提供する。
金属アミド前駆体がTEMAZ以外のテトラキス(エチルメチルアミノ)ハフニウム(TEMAH)であることを除いて、実施例1で規定されたものと同じ実験条件を用いてケイ酸ハフニウム膜を調製できる。
金属アミド前駆体がTEMAZ以外のテトラキス(エチルメチルアミノ)ハフニウム(TEMAH)であることを除いて、実施例2で規定されたものと同じ実験条件を用いてケイ酸ハフニウム膜を調製できる。
