Description
本発明は、半導体ウェハ等の被処理体に、一枚ずつ成膜処理等を施す熱処理装置に関する。
一般に、半導体集積回路の製造では、半導体ウェハ等の被処理体に、成膜処理、エッチング処理、酸化拡散処理等の各処理を行う。高集積化、高微細化および薄膜化が進む今日、上記処理における膜質の向上が大きな課題となっている。このような状況下において、良好な膜質の膜が得られる成膜方法として、原子層堆積法(Atomic Layer Deposition:以下、ALD)が開発されている。
以下、ALDを、原料ガスとして四塩化チタン(TiCl4)と、アンモニア(NH3)と、を用いて窒化チタン(TiN)成膜する場合を例として詳述する。
シャフト112の長さL1は、下端に設置されたシール部材114の耐熱性を考慮して設定されている。すなわち、長さL1は、例えば、30cm程度に設定され、載置台116が設置された上端と、下端との間で、十分な温度差を確保できるようになっている。また、シール部材114の保護のため、チャンバ104の底部には、冷却水が流れる冷却ジャケット124が設けられている。
上記目的を達成するため、本発明は、被処理体の高速な昇降温の可能な熱処理装置を提供することを目的とする。
以下、本発明の実施の形態に係る熱処理装置について、図面を参照して説明する。本実施の形態の熱処理装置は、原子層堆積法(Atomic Layer Deposition:ALD)により、半導体ウェハ(以下、ウェハW)の表面に、四塩化チタン(TiCl4)と、アンモニア(NH3)と、から窒化チタン(TiN)膜を成膜する。
配線管26とチャンバ12底部との接続部は、Oリング等のシール部材30によってシールされている。
一方、ガス吸引管34は、ポンプ40に接続されている。なお、ガス吸引管34は、APC(Auto Pressure Controller)を介してポンプ40に接続されても良い。
また、ヒータ板21は、耐熱性および耐腐食性の良好なAlNセラミックから構成した。しかし、これに限定されず、ヒータ板21は、他のセラミック材料、または、セラミック以外の材料から構成することができる。
本発明は、半導体装置等の電子デバイスの製造に有効に使用可能である。
本発明は、2000年9月29日に出願された、特願2000−300398号に基づき、その明細書、特許請求の範囲、図面および要約書を含む。上記出願における開示は、本明細書中にその全体が引例として含まれる。
