窒素保護の下、2,4,6,8−テトラメチルシクロテトラシロキサン(400g、1.66mol)を、Ru3(CO)12(4.00g、0.00626mol)、ピロリジン(39.43g、0.554mol)、及びTHF(100g、1.39mol)の撹拌溶液に加えた。2時間の撹拌の後、撹拌反応混合物にピロリジンの第2の部分(39.43g、0.554mol)を加えた。4時間の撹拌の後、撹拌反応混合物にピロリジンの第3の部分(39.43g、0.554mol)を加えた。ガスバブルを発生させ、反応溶液を室温で夜通し撹拌した。溶媒を減圧下で除去し、分留により粗生成物を精製して、所望の生成物の2−ピロリジノ−2,4,6,8−テトラメチルシクロテトラシロキサンを得た。Gc−Ms分析は、以下の質量ピーク:m/z=309(M+)、295、281、267、253、240、226、208、194、180、166、148、134、120、106、84、71を示した。
窒素保護の下、2−クロロ−2,4,6,8−テトラメチルシクロテトラシロキサン(0.15g、0.00055mol)を、ヘキサン(1mL)中のN−シクロヘキシルメチルアミン(0.09g、0.0008mol)及びトリエチルアミン(0.07g、0.0007mol)の撹拌溶液に滴下して加えた。得られた白色のスラリーを室温で夜通し撹拌した。固形物を濾過により除去して、濾過物をGC−MSにより所望の生成物の2−シクロヘキシルメチルアミノ−2,4,6,8−テトラメチルシクロテトラシロキサンが含有されていることを決定した。GC−MSは、以下のピーク:m/z=351(M+)、336(M‐15)、323、308、292、280、266、252、239、225、207、193、179、165、154、147、133、123、112、98、83、73を示した。
例1及び2に記載したのと同様に、追加の有機アミノ官能化環状オリゴシロキサンを合成し、GC−MSにより特徴付けた。それらの種類を特定するために、各化合物の分子量(MW)、構造及び関連する主要なMSフラグメントピークを表2に示した。
2−ピロリジノ−2,4,6,8−テトラメチルシクロテトラシロキサンを80℃で7日間加熱した。2−ピロリジノ−2,4,6,8−テトラメチルシクロテトラシロキサンの含有量を、GC分析によって測定した結果、99.24%から98.95%の平均値まで低下し、2−ピロリジノ−2,4,6,8−テトラメチルシクロテトラシロキサンが優れた熱安定性を示すこと、及び、気相堆積プロセスのための前駆体として適していることを示した。
電極間に3.5mmの固定スペースを持つ27.1MHz直接プラズマ能力を備えた商業的な横型流れ反応器(300mmPEALDツール、ASM製)においてプラズマALD(PEALD)を行った。ステンレス鋼バブラーにおいて前駆体を70℃まで加熱し、Arキャリアガスと共にチャンバーに輸送した。報告する全ての堆積は、天然酸化物含有Si基材上で行った。膜の厚さ及び反射率についてFilmTek2000SEエリプソメーターを用いて測定した。ウェットエッチ速度(WER)についての測定を、1:99(0.5wt%)に希釈したフッ酸(HF)溶液を用いて行った。各セットの実験のための標準として熱酸化物ウエハを使用し、エッチ溶液の活性を確認した。バルク膜のWERを収集し始める前に、試料を全て15秒間エッチングして任意の表面層を除去した。1:99(0.5wt%)dHF水溶液での典型的な熱酸化物ウエハのウェットエッチ速度はこの手順では0.5Å/秒であった。
ケイ素前駆体として2−ピロリジノ−2,4,6,8−テトラメチルシクロテトラシロキサンを使用して酸化ケイ素膜の原子層堆積を行う。堆積は実験室規模のALD処理ツールで行う。ケイ素前駆体をベーパードローでチャンバーに輸送する。全てのガス(例えば、パージ及び反応ガス又は前駆体、並びに、酸素源)を堆積領域に導入する前に100℃で予備加熱する。堆積で使用する基材は12インチ長ケイ素ストリップである。試料ホルダー上に熱電対を取り付けて基材温度を確認する。酸素源ガスとしてオゾンを使用して堆積を行う。堆積プロセス及びパラメーターを表8に示す。工程1〜6を所望の厚さが達成されるまで繰り返す。
ケイ素前駆体としてTMCTS及びO2プラズマ反応剤を用いて堆積を行った。TMCTSをベーパードロー法でチャンバーに輸送し、キャリアガスは使用しなかった。表1の工程b〜eを複数回繰り返して、計測のための所望の厚さの酸化ケイ素を得た。膜堆積パラメーター及び堆積GPC及びウエハ均一性を表9に示す。堆積ウエハは、悪い均一性を示し、GPCは前駆体パルスを増加させても飽和せず、TMCTSについてはCVD堆積であったことを示した。したがって、非官能化環状オリゴシロキサンTMCTSは、ALD前駆体として適さない。
ケイ素前駆体としてBDEAS及びO2プラズマを用いて上述した表1の条件で堆積を行った。前駆体を200sccmのキャリアガスAr流を用いてチャンバーに輸送した。工程b〜eを複数回繰り返して、計測のための所望の厚さの酸化ケイ素を得た。膜堆積パラメーター及び堆積GPCを表10に示す。図1は、様々な前駆体流時間に対するGPCを示す。BDEASは、2−ピロリジノ−2,4,6,8−テトラメチルシクロテトラシロキサンに比べて極めて低いGPCを示した。
