Abstract
Description
(式中、各R1は、独立して、水素又はC1-C4アルキルから選択され、各R2は、独立して、クロロ、ブロモ、ヨード、水素又はC1-C4アルキルから選択され、但し、2つ以上のR2が、クロロ、ブロモ又はヨードから選択される)を提供する。一実施形態では、各R1は、水素である。別の実施形態では、各R2は、クロロ、ブロモ又はヨードから選択される。別の実施形態では、各R1は水素であり、各R2はクロロ、すなわち式
の化合物であり、本明細書では頭字語「BTCSE」と呼ばれる。
トリクロロビニルシラン(500.0g、3.1モル)、トリクロロシラン(419.4g、3.1モル)、及びテトラキス(トリフェニルホスシン)パラジウム(0)(1.8g)を1Lの三つ口丸底フラスコに入れた。反応混合物を192℃で加熱した。温度が192℃に達した後、反応混合物を80℃で冷却した。生成物を、20torr下、80℃での単純蒸留によって精製して、最終生成物を無色の液体として得た(825g、89.7%)。生成物は純度98%超であることが分かった。
酸化ケイ素膜を、40℃のバブラーに入れたビス(トリクロロシリル)エタンで堆積させた。ダブルシャワーヘッドALD反応器を使用して、ウエハ温度として450℃~650℃のオゾン反応物を用いてケイ素ウエハ上に酸化ケイ素膜を堆積させ、反応器圧力を0.5~1.5Torrに制御した。酸化ケイ素堆積に続いて、21秒のケイ素パルス、20秒のArパージ、30秒のオゾンパルス及び20秒のArパージを行った。このサイクルを190サイクル繰り返し、膜厚を300Åとした。膜中に炭素及び塩素不純物がなく、650℃で約1.57/サイクルで飽和した。0.2% HF希釈溶液を用いて膜の湿式エッチング速度を62Å/分で得た。
窒化ケイ素膜を、40℃のバブラーに入れたビス(トリクロロシリル)エタンで堆積させた。ダブルシャワーヘッドALD反応器を使用して、ウエハ温度として600℃~725℃のアンモニア反応物を用いてケイ素ウエハ上に窒化ケイ素膜を堆積させ、反応器圧力を0.5~1.5Torrに制御した。窒化ケイ素堆積に続いて、21秒のケイ素パルス、20秒のArパージ、25秒のアンモニアパルス及び20秒のArパージを行った。このサイクルを190サイクル繰り返し、膜厚を400Åとした。これは、725℃で約1.45/サイクル飽和し、10%未満の炭素を含み、膜中に塩素不純物は含まれていなかった。得られた膜の湿式エッチング速度は、0.1% HF希釈溶液を用いて1.7Å/分であった。
実施例3に記載したのと同様の方法を用いて、ビス(トリクロロシリル)エタンを用いてオキシ炭窒化ケイ素膜を成膜した。クーポン温度として450℃及び515℃のアンモニア共反応物を有するケイ素クーポン上にSiOCN膜を堆積させ、反応器圧力を2Torrに制御した。ケイ素堆積に続いて16秒間のアンモニアパルスを行い、サイクルを繰り返して150~200Åの膜厚を得た。図9に示すように、成長速度は450℃で0.3Å/サイクル及び515℃で0.23Å/サイクルであることが分かった。得られたフィルム組成物を図10A及び図10Bに示す。
