Description
冷却管を備えた反応容器に、窒素置換しながら、脱水処理したメチルアミン塩酸塩(33.5g)、および溶媒であるトリグライム(98.6g)を仕込み、100℃まで昇温させた。100℃に維持しながら、水素化ホウ素ナトリウム(21.0g)とトリグライム(88.7g)との混合液を1時間かけて添加し、その後、反応溶液を2時間かけて180℃まで昇温させて、さらに180℃にて2時間熟成した。
蒸留精製を一度だけ行ったこと以外は、上記の実施例と同様の手法により、比較例1の化学気相成長成膜用組成物として、N,N’,N”−トリメチルボラジンを得た。
上記の実施例1および比較例1において得られたN,N’、N”−トリメチルボラジンにおけるハロゲン元素含有量および金属元素含有量を測定した。測定により得られた値を下記の表1に示す。なお、上記の実施例1および比較例1において、ハロゲン元素含有量の測定には、イオンクロマトグラフィーであるICS−1500(日本ダイオネクス株式会社製)を用いた。また、金属元素含有量の測定には、ICP−MS(高周波発光質量分析器)であるELAN DRCII(株式会社パーキンエルマージャパン製)を用いた。
まず、金を蒸着したシリコンウェハ(下電極)を準備した。次いで、上記の実施例および比較例において得られたN,N’,N”−トリメチルボラジンを、アルゴンをキャリアガスとして、加熱された導入管を通じて、それぞれ前記下電極が置かれた反応容器中に導入した。この際、周波数13.56MHzのRFを100Wにて稼動させて、反応容器中で反応ガスをプラズマ化させるようにした。また、基板温度が300℃となるように加熱し、N,N’,N”−トリメチルボラジンからなる原料ガスの蒸気温度は150℃に設定した。さらに、得られた膜上に、上電極として直径0.3〜1.5mmの円形金電極パターンをスパッタリング法により形成して、1MHzにおける上下電極間の電気容量を測定し、得られた電気容量を上電極面積で除し、膜厚を積算することにより、誘電率を算出した。その結果、実施例1の組成物を用いて成膜された膜の誘電率は2.50であったのに対し、比較例1の組成物を用いて成膜された膜の誘電率は3.08であった。
3L5つ口丸底フラスコに、モノメチルアミン塩酸塩(468g;6.931mol)、およびクロロベンゼン(2000mL)を全量入れた。このフラスコ内に、三塩化ホウ素(870g;7.389mol)をガスボンベから直接取り出し、−70℃で液化させながら、20時間かけて滴下した。滴下後、125〜135℃で60時間熟成し、ハロゲン化ボラジン化合物であるB,B’,B”−トリクロロ−N,N’,N”−トリメチルボラジン(TCTMB)の合成反応を終了させた。
日本ダイオネクス株式会社製DX−500を用いて、ハロゲン元素量を測定した。カラムは、分離カラムとしてIonPacAS4A−SC、ガードカラムとしてIonPacAG4A−SCをそれぞれ用いた。溶離液は、1.8mmol/リットルのNa2CO3溶液、および1.7mmol/リットルのNaHCO3溶液をそれぞれ用いた。溶離液の流量は、1.5ml/minとした。試料の注入量は、25μリットルとした。
ICPまたは原子吸光を用いて、金属元素含有量を測定した。ICPは、セイコー電子工業株式会社製SPS4000を用いた。原子吸光は、4110ZL(Perkin Elmer社製)を用いた。ICPの測定に対して感度の良いマグネシウムはICPを用いて測定し、その他の元素は原子吸光を用いて測定した。ICPの測定は、試料をDMSO/MeOHで10倍に希釈したサンプルを用いて行った。装置の設定値は、測定波長を279.553nm、高周波出力を1.80kW、キャリアガス(Ar)流量を0.6L/minとした。原子吸光の測定は、試料を超純水で10倍に希釈したサンプルを用いて行った。各元素の波長およびファーネスプログラムは以下の通りである。
グリニャール試薬をエチルマグネシウムブロマイドのジエチルエーテル溶液(3.0M、800ml)とし、昇華精製を蒸留精製とした以外は、参考例2と同様にして、B,B’,B”−トリエチル−N,N’,N”−トリメチルボラジン(TETMB)を合成した。
精製を一回だけ行った以外は参考例2と同様の方法により、塩素原子含有量が115ppm、臭素原子含有量が15ppmである、HMBからなる化学気相成長成膜用組成物を得た。この組成物を用いて成膜したところ、得られた膜の誘電率は3.11であった(表2)。
精製を一回だけ行った以外は参考例3と同様の方法により、塩素原子含有量が48ppm、臭素原子含有量が24ppmである、TETMBからなる化学気相成長成膜用組成物を得た。この組成物を用いて成膜したところ、得られた膜の誘電率は3.08であった(表2)。
