Description
現在の高純度アンモニアの供給機器を構成する金属材料としては、ステンレス鋼、例えばSUS316Lなどが用いられている。また、樹脂材料としては、一般にフッ素樹脂、具体的には、ポリクロロトリフルオロエチレン(PCTFE)、ポリテトラフルオロエチレン(PTFE)が用いられており、例えば、特許文献1(特開平6−24737号公報)には、アンモニアガスを精製するためのフィルターにフッ素樹脂を用いる発明が開示さ
れている。
路の下流にあるガス供給機器の内部やデバイス製造装置内から検出されたことから、当該機器の使用により当初の供給純度を提供できず、製造プロセス末端でのデバイスへの汚染を引き起こすというメカニズムも明らかにした。
(1)高純度アンモニアガス供給機器において、該供給機器のシール部および/または接ガス部が、ハロゲンを含まない樹脂によって構成されていることを特徴とする高純度アンモニアガス供給機器。
前記シール部本体がハロゲンを含まない樹脂から構成されるとともに、
前記当接部材の少なくとも前記シール部本体との当接部が、ステンレス鋼、コバルト基合金、高耐食性ニッケル基合金、または、アルミナ、窒化アルミニウムおよび炭化珪素からなる群より選ばれるセラミックスによって構成されていることを特徴とする高純度アンモニアガス供給機器。
(6)上記高純度アンモニアガス供給機器が、圧力調整器であることを特徴とする上記(1)〜(4)のいずれかに記載の高純度アンモニアガス供給機器。
(8)上記高純度アンモニアガス供給機器が、ラインフィルターであることを特徴とする上記(1)〜(4)のいずれかに記載の高純度アンモニアガス供給機器。
(10)上記(5)〜(9)のいずれかに記載の高純度アンモニアガス供給機器を用いて、高純度アンモニアガスを供給するガス流路を構成することにより、そのガス純度を劣化させることなく、高純度アンモニアガスを供給することを特徴とする高純度アンモニアガス供給方法。
れ、前記シール部本体がハロゲンを含まない樹脂から構成されるとともに、前記当接部材がアンモニアガス供給機器としての必要な性質を有することが好ましい。
、ジルコニア(ZrO2)、窒化チタン(TiN)および窒化クロム(CrN)からなる
群より選ばれるセラミックスでもよい。また、これらのセラミックスは混合物として用いることもできる。
本発明に係る高純度アンモニアガス供給方法は、上記のような高純度アンモニアガス供給機器を用いて、高純度アンモニアガスを供給するガス流路を構成することにより、そのガス純度を劣化させることなく、半導体デバイス製造装置に高純度アンモニアガスを安定的に供給できることを特徴とする。
以下、本発明を実施例により説明するが、本発明はこれら実施例により何ら限定されるものではない。
高純度アンモニアガスに対するガス供給機器のシール部の腐食性、圧力調整器における出流れ現象などを試験するための試験装置を図1に示す。図1に示すように、ガスボンベ1と圧力調整器2を配管にてつなぎ込み、圧力調整器2の前後に圧力計3および4を配置し、圧力調整器2の動作不良をこの二つの圧力計の指示値に現れる変化で確認できる構造とした。使用したガスはガス除害処理装置6で回収し処理した。本実施例で用いた圧力調整器2の内部構造の簡易図を図2に示す。
実施例と同様に図1に示すように、ガスボンベ1と圧力調整器2を配管にてつなぎ込み、圧力指示値に現れる変化によってシール部材の状況を判断確認できる構造として試験を行った。使用したガスはガス除害処理装置6で回収し処理した。
、ポリクロロトリフルオロエチレン(PCTFE)樹脂を用い、この樹脂シート8に当接し、ガスの流路を遮断する当接部材である調整弁体11を構成する金属シール材として、比較例1ではステンレス316Lを用い、比較例2ではハステロイC−22を用いた。なお、圧力調整器2を構成するその他の金属部位については、ステンレス316Lを使用した。
表3の結果から、実施例1のフェノール樹脂は、アンモニアガスの浸透による重量増加が認められるが、アンモニアガスに対する耐食性に優れており、樹脂シール材として用いることが可能であることがわかった。実施例2、3および4の結果から、ポリフェニレンサルファイド樹脂、ポリエーテルエーテルケトン樹脂は、重量変化は認められず、アンモニアガスに対して優れた耐食性を示していた。比較例1および2のPTCFE樹脂については一定の重量減少が認められた。比較例1の数値が比較例2の数値より低い理由は、測定した樹脂には外観上茶褐色の物質が付着しており、脱ハロゲン化によって腐食した金属シール材の腐食生成物が樹脂に付着したためと考えられる。
図3より、比較例1においては、PTCFEとアンモニアによる脱ハロゲン化反応によって生じたハロゲン含有生成物が、金属シール材に対して反応し、著しい腐食を発生させている。これに対して実施例1の金属シール材は腐食が認められず、金属光沢を維持している。その結果、圧力調整器の出流れ現象が全く認められなくなった。
応生成物等の有無を電子顕微鏡にて観察を行い確認した。また、生じた反応生成物をエネルギー分散型X線分析装置にて元素分析を行った。これらの結果を図5に示す。
