Description
このようなゲート絶縁膜としては、具体的には、SiO2またはSiONからなる第1絶縁膜と、前記第1絶縁膜上に形成されたHfO2、HfAlOx、HfSiONなどのハフニウムを含む高誘電体膜とからなる第2絶縁膜との組合せが提案されている。
前記ALD法によって、例えばHfAlOxからなる高誘電体膜を成膜する方法の一例を以下に説明する。
また、米国特許第6187665号明細書には、シリコン基板上に熱酸化によってシリカからなるゲート絶縁膜を形成し、前記ゲート絶縁膜のトラップサイトに重水素を含有させることにより、ゲート絶縁膜中にトラップされる電荷を増加させるホットキャリアがトラップサイトに蓄積することを防止し、デバイスを劣化させないようにする技術が開示されている。
このように、シリカからなるゲート絶縁膜に重水素を含有させて電界効果トランジスタの性能の改善を図ることは公知である。
請求項1にかかる発明は、基板を装填した処理室内部を真空にする工程Aと、原料化合物を前記処理室内に導入し、前記基板表面に吸着させる工程Bと、余分な前記原料化合物と副生成物を前記処理室から排出する工程Cと、前記処理室内に酸化剤を導入して前記基板に吸着した原料化合物を酸化する工程Dと、余分な前記酸化剤と副生成物を前記処理室から排出する工程Eを有し、前記工程Bから前記工程Eを繰り返すことで、ハフニウム・シリコン・オキシナイトライド(HfSiON)またはハフニウム・アルミネイト(HfAlOx)からなり、水素に対して0.05〜50%の割合で重水素が含まれるゲート絶縁膜を成膜するゲート絶縁膜の製造方法であって、
前記原料化合物が、ハフニウム化合物を含む1種以上の化合物であって、これら原料化合物を前記工程Bにおいてその種類毎に順次前記処理室内に導入し、
前記酸化剤として重水素とオゾンとを用いることを特徴とするゲート絶縁膜の製造方法である。
図1は、本発明の半導体集積回路装置の一例を示すもので、図中符号1はシリコン基板を示す。前記シリコン基板1には不純物が注入され、拡散層2が形成されている。また、前記シリコン基板1の素子分離領域4で分離された領域には、第1絶縁膜6と、前記第1絶縁膜6上の第2絶縁膜8とからなるゲート絶縁膜が形成されている。
また、前記記第2絶縁膜8は、例えば、HfO2、HfSiON、HfAlOxなどのハフニウムを含み、高誘電率を示す厚さ1.5〜3nmの薄膜である。
前記ゲート絶縁膜上には、ポリシリコンからなるゲート電極10が形成されている。
前記シリコン基板1の表面の前記ゲート電極10より外側に、比較的不純物濃度が低い拡散層であるSDエクステンション14が形成されている。また、前記シリコン基板1表面付近の前記SDエスクテンション14より外側で、かつ前記サイドウォール12より外側部分に、比較的結合深さが深く、かつ不純物濃度が高い拡散層であるソース/ドレイン16が形成されている。
まず、不純物を注入することにより拡散層2を形成したシリコン基板1上に、素子分離領域4を形成し、さらに各領域に分離したシリコン基板1の表面を希薄フッ酸を用いて洗浄する。希薄フッ酸処理後、図2に示すように、シリコン基板1上に第1絶縁膜6となるSiONを成膜する。ここでは、H2もしくはD2とN2Oを用いてSiONを成膜したが、熱酸化膜のプラズマ窒化や熱窒化膜の再酸化などの方法によって形成してもよい。
これにより、図3に示すように、基板1の第1絶縁膜6の表面にテトラキス(エチルメチルアミノ)ハフニウム(TEMAHf)の単分子層30が化学吸着により形成される。つぎに、処理室内をパージして余分のTEMAHfと副生成物とを排出する。
前記第2絶縁膜8には、約0.2at%の重水素が含まれていた。次に、希釈酸素雰囲気中で熱処理を行い、第2絶縁膜8を緻密化する。ここでは、0.2%希釈酸素雰囲気中で1000℃、1秒間の急速熱処理を施した。熱処理後、基板界面付近には約0.01at%の重水素が存在し、水素に対する重水素の比率は6%であった。
つぎに、図7に示すように、前記ゲート電極10の側面にサイドウォール12を形成する。前記サイドウォール12は、前記ゲート電極10を埋め込むようにして、SiN膜等を堆積した後、エッチバックを行い、SiN膜を前記ゲート電極10の側面にのみ残すようすることにより形成される。
ここで使用される重水、重水素は、鉄、銅などの金属不純物の含有量の総量が1wtppm以下であるものが好ましく、金属不純物の含有量がこれよりも多くなると、第2絶縁膜8のリーク電流が増大し、TDDB(タイム−ディペンダントダイエレクトリックブレイクダウン)の寿命低下など長期信頼性上の問題を引き起こす危険がある。
さらに、前記第2絶縁膜8に前記重水素を含有させる方法としては、前記第2絶縁膜8の成膜時ではなく、一連の集積回路装置の製造工程における前記活性化アニール工程の後に、重水素雰囲気中で400〜600℃、30分程度のシンタを行うことでも可能である。
図8は、前記ALD法により重水を酸化剤として使用し成膜したHfAlOx膜と、水を酸化剤として使用し同条件で成膜したHfAlOx膜との界面準位密度を測定し、比較して示したものである。
これらのグラフから、重水素を含有されるHfAlOx膜は、従来の重水素を含有しないHfAlOx膜に比べて、界面準位密度が1/2〜1/3に低減していることが明らかである。
図10および図11は、ALD法により重水を酸化剤として使用し成膜したHfAlOx膜と、水を酸化剤として使用し同条件で成膜したHfAlOx膜との移動度を測定し、比較して示したものである。
