Description
本出願は、2013年11月21日出願の「METHODS AND APPARATUS FOR REMOTE PLASMA TREATMENT FOR REDUCING METAL OXIDES ON A METAL SEED LAYER」という名称の米国特許出願第14/086,770号の優先権の利益を主張するものである。上記の特許出願は、2013年9月6日出願の「METHOD AND APPARATUS FOR REMOTE PLASMA TREATMENT FOR REDUCING METAL OXIDES ON A METAL SEED LAYER」という名称の米国特許出願第14/020,339号の一部継続出願であり、また、2013年3月6日出願の「METHODS FOR REDUCING METAL OXIDE SURFACES TO MODIFIED METAL SURFACES USING A GASEOUS REDUCING ENVIRONMENT」という名称の米国特許出願第13/787,499号の一部継続出願である。上記の特許出願すべてを参照によりあらゆる目的で本明細書に組み込む。
本開示は、一般に、金属シード層上の金属酸化物表面を還元することに関する。本開示の特定の態様は、遠隔プラズマ装置を使用して金属シード層上の金属酸化物表面を還元することに関する。
本発明は、様々な用途で使用することができるが、1つの非常に有用な用途は、半導体デバイスの製造で一般に使用されるダマシンまたはデュアルダマシンプロセスである。ダマシンまたはデュアルダマシンプロセスは、金属相互接続、例えば銅相互接続を含むことがある。
式1:2M(s)+O2(g)→2MOx(s)
式2:2M(s)+H2O(g)→M2Ox+H2(g)
遠隔プラズマを使用して金属シード層を有する基板を準備する方法を開示することができる。いくつかの実施形態では、基板は、還元ガス雰囲気への露出中に金属シード層の凝集を生じる温度未満の温度で維持される。いくつかの実施形態では、この方法はさらに、めっき溶液を含むめっき浴に基板を移送するステップと、めっき溶液を使用して金属シード層上に金属をめっきするステップとを含む。
式3:H2→2H*
式4:(x)2H*+MOx→M+(x)H2O
式5:xH2 +MOx→M+xH2O
金属シード層を有する基板を準備するための遠隔プラズマ装置が開示される。遠隔プラズマ装置は、処理チャンバと、処理チャンバの上方にある遠隔プラズマ源と、制御装置とを含む。いくつかの実施形態では、遠隔プラズマ装置は、さらに、処理チャンバ内で基板を保持するための基板支持体と、遠隔プラズマ源と基板支持体との間のシャワーヘッドとを含む。いくつかの実施形態では、遠隔プラズマ装置は、さらに、処理チャンバ内に1つまたは複数の可動部材を含む。1つまたは複数の可動部材は、シャワーヘッドと基板支持体との間の位置に基板を移動させるように構成することができる。制御装置は、処理チャンバ内に、基板のめっき表面上に金属シード層を有する基板を提供する操作であって、金属シード層の一部が金属の酸化物に変換されている操作と、遠隔プラズマ源内で還元ガス種の遠隔プラズマを生成する操作であって、遠隔プラズマが、還元ガス種からのラジカル、イオン、およびUV放射の1つまたは複数を含む操作と、遠隔プラズマに基板の金属シード層を露出させる操作であって、遠隔プラズマへの露出が、金属の酸化物を、金属シード層と一体化された被膜の形態での金属に還元する操作とを実施するように構成することができる。また、制御装置は、基板の金属シード層を遠隔プラズマに露出させる前に1つまたは複数の可動部材によって基板を基板支持体に向けて移動させる操作と、基板を冷却ガスに露出させる操作とを含めた、1つまたは複数の操作を実施するように構成することもできる。
図9は、遠隔プラズマへの露出と、銅に関する導電率の利得との影響関係を示すグラフである。遠隔プラズマを用いて銅シード層を含む基板を前処理しない場合、銅の表面での導電率の変化は、ほぼ無視することができる。しかし、75℃に加熱された基板を遠隔プラズマを用いて処理することが、銅シード層の表面での導電率をかなり高める。30秒、60秒、および120秒のいずれの期間にわたって遠隔プラズマ処理が行われたかに関わらず、効果はほぼ変わらなかった。したがって、遠隔プラズマを用いた前処理は、純金属銅に対する酸化銅の存在を効果的に減少させて、導電率を高める。
明瞭になるように、かつ理解しやすいように、いくらか詳細に上述してきたが、添付の特許請求の範囲の範囲内で何らかの変更および修正を行うことができることを理解されたい。説明したプロセス、システム、および装置を実装する多くの代替形態が存在することに留意すべきである。したがって、説明した実施形態は、例示とみなすべきであり、限定とみなすべきではない。本発明は、以下の適用例としても実施可能である。
