Description
5.24gのシクロデキストリンは、20mLのジメチルホルムアミド(DMF)に溶解され、NaHが溶解されているDMF溶液に徐々に加えられて、脱水素を誘導した後、21mLの臭化アリルが滴下して加えられ、溶媒及び余剰の臭化アリルを除去して、アリル基を含有するシクロデキストリンを製造する。
実施例1
マトリクス成分として、ポリメチルシルセスキオキサン前駆体(GR650FTM,Si−OH/Si原子比=9%)またはポリメチルシルセスキオキサン共重合体は、酢酸n−ブチルを用いて20wt.%の濃度で製造された。ポリメチルシルセスキオキサン共重合体は、韓国特許公開出願第2002−38540号に開示され、メチルトリメトキシシランとα,ω−ビストリメトキシシリルエタンが9:1のモル比で混合された共重合体である。
上記作成例において製造されたヘプタキス(2,3,6−トリ−O−(3−トリエトキシシリルプロピル)−β−シクロデキストリン)(TESCD)をTHFに約3〜20wt.%の濃度で溶解し、少量の水及びHCl触媒を滴下して加えた後、0℃で約2〜4時間ゾル−ゲル反応を実施した。触媒の除去は、反応混合物に過剰のジエチルエテール及び水を添加して、ジエチルエーテルを再び除去することにより行われ、最終的にゾル状態のケイ酸塩マトリクス前駆体を製造した。このように作成されたケイ酸塩前駆体は、再び酢酸n−ブチル溶媒に約10〜50wt.%の濃度で溶解し、続いて実施例1と同様にスピンコーティング及び熱処理を行って、ナノ気孔を含有し、優れた機械的特性を有するケイ酸塩低誘電体膜(メンブレン)が最終的に製造された。
ポロゲンとしてヘプタキス(2,3,6−トリアセチル)−β−シクロデキストリン)(TABCD)を使用したことを除いて、ナノ気孔を含有する低誘電体膜が実施例1のように製造された。
低誘電体薄膜は、サイクリックシルセスキオキサン(CSSQ)を用いて製造され、韓国特許公開出願第2002−75720号に開示され、韓国のサムスン アドバンスト インスティテュート オブ テクノロジー(Samsung Advanced Institute of Technology)で製造された低誘電体膜が、マトリクスとして用いられ、また、ヘプタキス(2,3,6−トリ−O−メチル)−β−シクロデキストリン)(tCD)が、ポロゲンとして使用された。比較例2の実験方法及び物質の性質(物性)は、上記韓国特許出願から引用する。
薄膜の屈折率及び厚さは、エリプソメーター(L166C,ガートナー サイエンティフィック コーポレーション(Gaertner Scientific Corp.))を使用して632.8nmで測定された。薄膜の多孔率は、下記数式1に表されるローレンツ−ローレンツ式を用いて計算された。
