Description
[0002]集積回路及び半導体デバイスの製造に使用される基板に酸化物のような材料を堆積するために、化学気相堆積(CVD)チャンバを使用することができる。CVDチャンバでは、ガスをチャンバへ均一に分配するのにガス分配プレートが通常使用される。このような均一なガス分配は、チャンバ内に置かれた基板の表面に材料の均一な堆積を達成するのに必要とされる。ガス分配プレートは、一般に、ガス分配プレートの上のガスボックスとしても知られている混合領域から堆積ガスを受け取る。ガスボックスへのガス導入通路は、通常、ほぼ100℃以下の温度に水冷される。ガス分配プレートの下で基板支持部材にヒータが一般に配置される。ヒータは、通常、ほぼ100から600℃の温度に加熱される。従って、ガス分配プレートの温度は、ガス導入通路の温度とヒータの温度との間のどこかである。しかしながら、ガス分配プレートは、ガス導入通路に接続されるので、ガス分配プレートの温度は、一般に、ヒータの温度より、ガス導入通路の温度に近いものとなる。
本発明は、一般に、処理領域で基板に化学気相堆積を行うためのチャンバであって、ガス入口通路を有する加熱ガスボックスと、この加熱ガスボックスから基板処理領域へガスを導通するように位置されたフェースプレートとを備えたチャンバを提供する。また、本発明は、化学気相堆積チャンバへ熱を与えるための方法であって、基板支持体と、ガス入口通路を有するガスボックスとに熱を供給することを含む方法も提供する。フェースプレートではなくガスボックスを加熱することで、ガスボックス内の堆積を減少し、チャンバの清掃時間を短縮する。本発明は、堆積率が温度に逆比例するようなCVDプロセス、例えば、炭素ドープの酸化シリコン、酸素ドープの炭化シリコン、酸化シリコン、ドープされたアモルファス炭素、及び窒化シリコンを堆積するプロセスに対する清掃時間を短縮する。
[0015]本発明は、基板処理チャンバにおいて膜の化学気相堆積(CVD)を行うと共に、チャンバの改良された清掃を行う方法及び装置を提供する。ここに述べる装置及び方法から利益が得られる堆積チャンバは、炭素ドープの酸化シリコンのような酸化物、シリコン含有膜、及び進歩型パターン化膜(APF)を含む他の誘電体材料を堆積するのに使用できるチャンバを含む。堆積チャンバは、例えば、カリフォルニア州サンタクララのアプライドマテリアルズ社から入手できるProducer(登録商標)チャンバである。このProducer(登録商標)チャンバは、炭素ドープの酸化シリコン及び他の材料を堆積するのに使用できる2つの分離された処理領域をもつCVDチャンバである。2つの分離された処理領域を有するチャンバは、参考としてここに援用する米国特許第5,855,681号に説明されている。Producer(登録商標)チャンバは、遠隔プラズマ源を取り付けることのできるポートを有する。ここに述べる方法の実施形態には、コロラド州フォートコリンズのアドバンスト・エナージー・インダストリーズ社から入手できる遠隔プラズマ源、モデル番号5707024−Fを伴うProducer(登録商標)チャンバを使用することができる。
