を含む方法が提供される。幾つかの実施形態では、工程f)の前に工程b)〜e)を複数のサイクル繰り返す。一つの特定の実施形態では、ジエトキシメチルシランなどのSi−H結合を有する有機ケイ素化合物を工程b)で使用して銅酸化物の銅金属への還元を可能にし、こうして多孔質低k誘電体層の表面での細孔封止層の選択的堆積を容易にする。
様々な型の細孔封止層及び様々な伝導体(conductions)を堆積させるための様々な実験を200ミリメートル(mm)ウェハー上で実施し、その上に2.2の誘電率を有する多孔質ジエトキシメチルシラン膜の層を構造形成体ジエトキシメチルシラン(DEMS)前駆体及びポロゲン前駆体シクロオクタンから堆積させ、米国特許出願公開第2007/0299239号明細書に記載のように紫外線(UV)硬化した。
この例では本出願者等は、このプロセスで非窒素含有前駆体又はガスを使用することによって細孔封止層の誘電率を比較的低く保った。本出願者等はまた、銅表面の酸化を防ぐために酸素又は他のオキシダントの使用を排除した。損傷した多孔質低k膜を有機ケイ素化合物トリメトキシメチルシラン(C4H12O3Si)と接触させ、かつヘリウムプラズマで処理した。各サイクルにおいて、有機ケイ素前駆体化合物を反応器中に流し、その損傷した多孔質低k誘電体膜の表面に浴びせた後に200ワットHeプラズマを15秒間ぶつけ、次いでパージした。この過程を約10〜30回繰返して細孔封止層を得た。この細孔封止層は、観察される変色がないことによって、又は30サイクルの処理後にトルエン蒸気の拡散による楕円偏光スペクトルのシフトがないことによって立証されるようにトルエンが損傷した多孔質低k膜中に拡散していないので有効とみなされた。次に、Ta2O5層を続いて10サイクルの処理でウェハー(その上に細孔封止層を堆積されている)上に堆積させた。Ta含有層を堆積させた後、蛍光X線分析(XRE)によって試験されるように細孔中へのTaの拡散の兆候は存在しなかった。したがって損傷した細孔は、トリメトキシメチルシランとの10サイクルの接触及びHeプラズマによる処理の後、細孔封止層の形成によって封止される。
上記有機ケイ素化合物ジイソプロピルジメトキシシラン(C8H20OSi)を使用して細孔封止層を堆積した。これは、損傷していない低k膜と比較して誘電率を劇的に上昇させることなく細孔を封止するのに適していることが分かった。30サイクルまでの処理の場合、低k膜の誘電率は2.2の出発値から2.29の処理後の値まで増加(すなわち+0.09の変化)したに過ぎない。この有機ケイ素化合物はまた、Cu基材に対する比較的良好な選択性をもたらすことが分かった。すなわち20サイクルの処理の場合、低k膜上の細孔封止層の厚さが約20Åであるのに対し、Cu基材上の細孔封止層の厚さは3.4Å未満であり、約6:1の選択性を示した。
上記ジメチルジアセトキシシラン(C6H12O4Si)を使用して細孔封止層を堆積した。損傷した多孔質低k膜は、この有機ケイ素化合物との10サイクルの接触、次いでHeプラズマ処理で完全に封止された。この膜の堆積速度は〜1.2Å/サイクルであり、これは細孔が約1.2ナノメートル(nm)の厚さを有する細孔封止層で封止できることを示す。一方、キャップ層の誘電率は4未満であり、これもまたkの変化を低減する可能性がある。Ta2O5の堆積及びXRF分析は、細孔が封止され、細孔中へのTaの拡散がないことを示した。
式C7H16OSiを有する有機ケイ素前駆体1−メトキシ−1−エトキシ−1−シラシクロペンタンを上記と同様に試験した。NH3で損傷した膜は、10サイクルのHe又はArプラズマ処理で完全に封止することができる。Ta2O5の堆積及びXRF分析は、細孔が封止され、細孔中へのTaの拡散がないことを示す。動的SIMSのデータはまた、界面における劇的なTa濃度の降下を示し、これは本明細書中で述べた方法の10サイクルよる良好な細孔封止効果を示している。
上記と同様に損傷した多孔質低k誘電体膜を、式C8H22O6Si2を有する有機ケイ素化合物1,2−ビス(トリメトキシシリル)エタン((CH3O)3Si−(CH2)2−Si(OCH3)3)に接触させた。これを上記と同様にEP試験を使用して試験し、トルエンの拡散はなくEP試験に合格した。変色は観察されず、またエリプソメーターによるシフトは生じなかった。XRF分析はまた、1,2−ビス(トリメトキシシリル)エタンによる10サイクルの処理後の細孔中へのTaの拡散がないことを示した。
