Scientific journal, Hybrid bonding has become a promising approach to realizing fine pitch interconnection via bonding for both the wafer level and die level. The morphology and cleanliness of the bonding surface are critical to ensure a high yield. Therefore, surface planarization by chemical mechanical polishing (CMP) is considered a key process. The recess on the Cu pad must be controlled to be less than 5 nm by adjusting the removal rate between the Cu, the barrier layer, and the bonding dielectric layer. Conventionally, SiO2 has served as the bonding dielectric. However, SiCN is considered a promising dielectric because of its high bonding strength, suppression of voids, and ability to function as a Cu diffusion barrier. Here, we investigated simultaneous Cu, barrier, and SiCN CMP for hybrid bonding. Post-CMP processes such as cleaning and activation were also assessed. The results revealed that the removal rate of the three materials could be adjusted by dilution of the slurry and oxidizer. Lower selectivity was achieved at a certain dilution rate in an alkaline barrier slurry. Plasma activation revealed that the Cu passivation layer formed during cleaning was removed. Therefore, residues from CMP and post-CMP processes did not affect Cu prior to the hybrid bonding. - D2W Hybrid Bonding System Achieving High-Accuracy and High-Throughput With Minimal Configurations

デジタル社会の基盤技術であるAI半導体の高エネルギー効率化が急務となっており、半導体の前工程と後工程の融合による「3D集積技術」が革新的解決策とされている。半導体チップ上の電源電圧降下を効果的に抑制可能な裏面電源供給ネットワーク(BSPDN)はその代表的アーキテクチャであるが、歩留まりと放熱に課題を抱えており、設計、集積、プロセスに係る各基盤技術のシステム・製造協調最適化による解決が求められている。本研究開発では、3D集積関連の技術シーズをベースに半導体製造装置企業と連携して前工程/後工程の融合エコシステム型共同研究開発体制を構築し、革新的な解決策の提案と実用化を目指す。

微小ピッチ化したハイブリッド接合では Cuパッドのリセスを5 nm以下に抑えることを満たす必要がある。ALDやE-ALDを検討するにしても最低限のCMPの精度とハイブリッド接合の界面に関する基礎検討が必要である。2023年度はそれらの表面、界面における現象理解に着目し開発を進めた。ハイブリッド接合におけるCu-Cu接続のメカニズムはCuとILDの間の線熱膨張係数(CTE)の差に起因する接合後のアニーリング中のCuパンピング(またはCuバルジアウト)であることが知られている。Cuパッドが接続面の両側で大きく凹んでいる場合、Cuパッド間の隙間は閉じられないか、少なくとも塞ぐために許容される温度をはるかに超える温度域での熱処理が必要になる。ゆえにバリアCMP中Cu、バリアメタル SiCNの研磨速度の選択性は、高い接合率を実現するために非常に重要である。さらにCMP後の洗浄工程(P-CMP)では、Cu表面を変化させることなく残留スラリーや残留物、汚染を除去または低減することが求められる。Cu CMPのスラリーには通常、ベンゾトリアゾール(BTA)などの腐食防止剤が使用されている。これは高い不溶解性を持つため、CMP後もCu表面に残る可能性がある。腐食防止剤は、長い間Cu ダマシンプロセス用に研究されてきたが、Cu-Cu 結合の阻害剤となる可能性があるためハイブリッド接合に対しては、さらなる研究が必要である。BTAは、P-CMP工程で使用される洗浄液によって除去される可能性がある。しかし、洗浄液はCu表面に深刻な凹みを引き起こす可能性がある。したがって、私たちはCu/SiCNハイブリッド接合で用いられるCMP工程、特にCuパッド表面の凹みの低減に焦点を当てて、研究を行なった。

We evaluated the polishing rates of interconnect metal, barrier metal, and dielectric films using electrochemical measurements to optimize the chemical mechanical polishing (CMP) for the planarization of hybrid surfaces. The surface corrosion state was significantly affected by the addition of H2O2 as an oxidizing agent in the interconnect metal, while the surface state change due to H2O2 addition was smaller for the barrier metal, indicating the formation of a passive state. During the actual CMP process, the addition of H2O2 resulted in a noticeable increase in the polishing rate for the Cu sample, and the difference in polishing rates between the Cu and Ta samples became larger. Based on these results, it was elucidated that the slurry used in this study is more suitable for the planarization of hybrid bonding surfaces when H2O2 is not added as an oxidizing agent, as the corrosion rates of Cu and Ta are similar.
