Abstract
Description
窒化シリコン薄膜を形成する場合、先ず、前記で説明した原料導入工程により、本発明の化学気相成長用原料にプレカーサとして含まれる本発明に係る有機シリコン含有化合物を堆積反応部に導入する。次に、堆積反応部に導入したプレカーサにより、基体上にシリコン含有薄膜を成膜させる(シリコン含有薄膜成膜工程)。このときに、基体を加熱するか、堆積反応部を加熱して、熱を加えてもよい。この工程で成膜されるシリコン含有薄膜は、プレカーサ薄膜、または、プレカーサが分解および/または反応して生成した薄膜であり、純粋なシリコン含有薄膜とは異なる組成を有する。本工程が行われる温度が、50℃より低いと最終的に得られる窒化シリコン薄膜中に残留カーボンが多く含まれる場合があり、500℃を超えても、最終的に得られる膜質の向上は見られないので、基体または堆積反応部は、50~500℃に加熱することが好ましく、100~500℃に加熱することがさらに好ましい。
反応フラスコにHSiCl341.0g、メチルターシャルブチルエーテル(以下MTBEと言う)365mlを仕込み、-30℃に冷却した。これにNH(CH3)(C2H5)79.0gを反応系が-20℃を超えないように滴下した。滴下終了後、室温で3時間撹拌した後、加圧ろ過を行いMTBE71mlで洗浄し、減圧下、50℃でMTBEを留去した。残渣を減圧蒸留して、圧力1200Pa、留出温度53℃のフラクションから目的物であるHSiCl(N(CH3)(C2H5))2を収率70%で得た。得られた化合物については、1H-NMRの測定により同定を行った。
(5.126:s:1)(2.773:quartet:4)(2.365:s:6)(0.916:t:6)
反応フラスコにHSiCl375.0g、THF360mlを仕込み、0℃に冷却した。これにNH(C2H5)2165.33gとTHF70mlの混合溶液を反応系が5℃を超えないように滴下した。滴下終了後、室温で3時間撹拌した後、45℃に加熱して9時間撹拌した。次いで、加圧ろ過を行いTHFで洗浄し、減圧下、50℃でTHFを留去した。残渣を減圧蒸留して、圧力250Pa、留出温度44℃のフラクションから目的物であるHSiCl(N(C2H5)2)2を収率62%で得た。得られた化合物については、1H-NMRの測定により同定を行った。
(5.121:s:1)(2.835:quartet:8)(0.942:t:12)
反応フラスコにHSiCl375.0g、THF190mlを仕込み、0℃に冷却した。これにNH2(C(CH3)3)163.77gとTHF77mlの混合溶液を反応系が5℃を超えないように滴下した。滴下終了後、室温で3時間撹拌した後、55℃に加熱して4時間撹拌した。次いで、加圧ろ過を行いTHFで洗浄し、減圧下、50℃でTHFを留去した。残渣を減圧蒸留して、圧力1470Pa、留出温度74℃のフラクションから目的物であるHSiCl(HNC(CH3)3)2を収率62%で得た。得られた化合物については、1H-NMRの測定により同定を行った。
(5.440:s:1)(1.100:s:20)
上記の実施例1~3で得た化合物No.14、8、6および表1に示す比較化合物No.1~5について、TG-DTAを測定した。測定条件は、Ar100ml/min、10℃/min昇温とした。TG-DTA測定における50%減量温度、1段階目の減量終点温度と残量%についての結果を表2に示す。なお、ここでいう%は質量基準である。
化合物No.8または比較化合物No.1を1質量部、Ar雰囲気下のフラスコに入れ、室温および200℃でNH3ガスを30質量部吹き込んで得られた液相についてFT-IRを測定し、NH3ガス吹き込み前と比較した。結果を図1~図3に示す。
図1および図2では、NH3ガス吹き込み前には見られないH-SiN3のピークが吹き込み後に発現していることから、化合物No.8のSiに結合するClがNに変換されたことが分かった。このことから、化合物No.8がNH3ガスと反応したことが考えられた。一方、図3では、ピークの変化が見られず、比較化合物No.1はNH3ガスと反応しなかったことが分かった。これらの結果から、本発明の有機含有シリコン化合物はSi-Clを有するためにNH3ガスとの反応性が良好であることが分かった。
化合物No.8を1質量部、Ar雰囲気下のフラスコに入れ、室温でNH3ガスを30質量部吹き込んで得られた液相をSiウェーハ上に滴下し、Ar雰囲気下において700℃で10分間加熱した。Siウェーハについて、FT-IRを測定した結果を図4に示す。
図4では、1200cm-1付近のアルキル基および1000cm-1付近のアミノ基(C-N)のピークの消滅、ならびに800~900cm-1付近のSi-Nのピークの出現を確認した。このことよりSi-NXが生成したことが分かった。一方、比較化合物No.1について同様の評価を行なったが、ピークは確認できなかった。これらの結果から、化合物No.8は、Siウェーハ上に吸着して、アンモニアと反応して窒化シリコン膜を与えることができ、これに対し、比較化合物No.1は、Siウェーハ表面への吸着力が小さいため、Siウェーハ上に膜を形成しないことが確認できた。
上記実施例1で得た化合物No.8を化学気相成長用原料とし、図5に示す装置を用いて以下の条件および工程のALD法により、Siウェーハ上に窒化シリコン薄膜を製造した。得られた薄膜について、蛍光X線による膜厚測定、薄膜組成の確認を行ったところ、膜厚は20nmであり、膜組成は窒化シリコンであり、炭素含有量は0.5atom%であった。
