Abstract
【選択図】 図2
Description
[0001]本発明の実施形態は、一般的に半導体製造の分野に関する。より具体的には、本発明はシリコンオキシニトライド(SiOxNy)ゲート誘電体の形成方法と、さらに、これを、プラズマ窒化および2段階式のプラズマ窒化後アニーリング(PNA)処理を使用してゲートスタック内に統合する方法とに関する。
[0002]集積回路は、トランジスタ、キャパシタ、抵抗器のような基本構成部品として機能する、文字通り多数の動的または静的デバイスで作成されている。一般的に、トランジスタはソース、ドレイン、ゲートスタックを含む。ゲートスタックは基板(シリコン)からなり、この基板の頂部に誘電体(通常は二酸化シリコン:SiO2)を成長させて、これを電極(例えば多結晶シリコン)で覆っている。
[0032]さらなる実施形態では、SiOxNyゲート誘電体が、統合型半導体処理システムのような統合型処理システム内の基板上に形成される。この形成は、SiOxNyゲート誘電体が形成されるまで、統合型処理システムから基板を除去しない方法において行われる。使用できる統合型処理システム100の1例には、図1に示した、カリフォルニア州サンタクララにあるApplied Materials,Inc.より市販されているゲート・スタック・センチュラ(Gate Stack Centura)(登録商標)システムがある。統合型処理システム100は、中央移送チャンバ102、移送ロボット103、負荷ロック104、106、冷却チャンバ108、堆積チャンバ110、プラズマ処理チャンバ114、2つの急速加熱処理(RTP)チャンバ116、118を含む。堆積チャンバ110は、当分野において既知の、膜または層の形成に使用できる従来の化学または物理気相堆積であってもよい。一実施形態では、CVD処理チャンバ110は低圧化学気相堆積チャンバ(LPCVD)、例えばApplied Materials社から入手可能なPOLYgenチャンバである。RTPチャンバ116、118は、低下した圧力または超低圧(例えば、10トールと等しい、またはこれよりも低い圧力)で急速加熱アニーリング(RTA)処理を遂行できるチャンバである。
[0045]図4に示すように、シリコンオキシナイトライドの2段階式ポストアニールの第1段階に微量の酸素を含ませることで、NMOSゲート漏出に対するNMOS駆動電流が向上する。図4では、x軸がNMOSゲート漏出を表し、y軸がNMOS駆動電流を表わす。一例として、約10ÅのSiO2膜がベース酸化物として使用されている。プラズマ窒化後に、様々なポストアニーリング条件を使用して膜のアニーリングを行う。例えば、1000℃の温度で、30秒間、窒素ガスが存在する状態で15ミリトールの酸素部分圧におけるアニーリングが関与する第1段階の後に、1000℃の温度で15秒間、10トールの酸素圧におけるアニーリングが関与する第2段階が続く。別の例では、1000℃の温度で15秒間、窒素ガスが存在する状態で15ミリトールの酸素圧におけるアニーリングが関与する第1段階の後に、1050℃の温度で15秒間、1.5トールの酸素圧におけるアニーリングが関与する第2段階が続く。また別の例では、1050℃の温度で30秒間、窒素ガスが存在する状態で15ミリトールの酸素圧におけるアニーリングが関与する第1段階の後に、1050℃の温度で15秒間、0.5トールの酸素圧におけるアニーリングが関与する第2段階が続く。別の例では、1000℃の温度で、30秒間、窒素ガスが存在する状態で0.015ミリトールの酸素圧におけるアニーリングが関与する第1段階の後に、1100℃の温度で、5秒間、0.05トールの酸素圧におけるアニーリングが関与する第2段階が続く。図1に示すように、第1ステップ内に微量の酸素を含有する2段階式ポストアニールは、第1段階中に微量の酸素を設けていない2段階式ポストアニールと比べ、NMOS Idsatの4%の向上を呈した。
