Abstract
Description
以下の一般式(I)、
細孔充填ポリマー1(PFP−1):
NORYL(商標)SA90樹脂(SABIC,Pittsfield,Massachusetts USA)を出発物質として使用した。このポリマーのGPC分析は、標準ポリスチレン換算で、3600の重量平均分子量Mw、及び1.6の多分散度指数Mw/Mnを示した。このポリマーを、以下の手順に従って分画した。150gのテトラヒドロフラン中の50gのポリマーの溶液を、1.5gのイソプロパノール中に激しく攪拌しながら緩徐に注ぎ入れた。結果として得られた沈殿物を濾過し、1リットルのイソプロピルアルコールで洗浄し、夜通し空気乾燥させ、次いで真空下48時間60℃で乾燥させて、標準ポリスチレン換算で、4590の重量平均分子量Mw、及び1.38の多分散度指数Mw/Mnを有する、27gの分画されたポリマーを生成した。
ポリ(ベンゾフェノン−ビスフェノール−A)(ポリ(BPA−PBH))(PFP−2)を、スキーム2に示される反応に従って調製した。
細孔充填組成物1(PFC−1):
ポリマーPFP−1をアニソール中に溶解させて、3.6重量%の溶液を形成した。0.2ミクロンの孔径を有するテフロン(登録商標)フィルタにこの溶液を通して濾過して、細孔充填組成物PFC−1を形成した。
14.4%の多孔度及び1000Åの硬化厚さを有する、PECVD堆積Black Diamond(商標)IIナノ多孔質低誘電率膜(Applied Materials)でコーティングされたシリコンウェハを提供した。細孔充填組成物PFC−1を、多孔質膜でコーティングされたウェハ上、及びベアシリコンモニタウェハ上に1500rpmでスピンコーティングし、続いて150℃で2分間ソフトベークして、モニタウェハに基づいて100nmのポリマーの厚さを生み出した。次に、多孔質膜でコーティングされたウェハを、窒素雰囲気下の熱板上で、5分間300℃で加熱した。ウェハを、2500rpmのスピンコータ上で60秒間、25℃のアニソールを用いて3回すすいで、残留(過剰に積載された)細孔充填材料をウェハ表面から除去した。ウェハを200℃で5分間ベークして、残留溶剤を除去した。
表1に列挙された塊状ポリマーについての熱安定性を、窒素雰囲気下にて10℃/分の加熱速度での熱重量分析(TGA)によって測定した。これらのポリマーには、ポリスチレン(比較用)(標準ポリスチレン換算で、Mw=17000、Mw/Mn=1.05)、ポリマーP1(比較用)(NORYL(商標)SA9000樹脂)、PFP−1、及びPFP−2が含まれた。原重量に基づく、400℃でポリマーの残留重量パーセント、ならびにポリマーの5%及び10%の重量損失における温度を決定した。ポリマーPFP−1及びPFP−2は、ポリスチレン及びポリマーP−9と比較して、400℃で有意に低い重量損失を呈した。加えて、ポリマーPFP−1及びPFP−2について、5%及び10%の重量損失が起こった温度は、比較用ポリマーP1及びポリスチレンポリマーについて観察された温度よりも有意に高かった。
