Through-silicon vias (TSVs) is one of the key technologies for 3D integration. To solve the issues induced by the high-Temperature process for TSV liner formation in the multichip-To-wafer (MCtW) process, we applied the low-Temperature SiO2 deposition method called OER (Ozone-Ethylene Radical generation)-TEOS-CVD®. In this study, we fabricated the MIS capacitors with the TSV liner deposited by OER-TEOS-CVD® at 150°C and room temperature (RT), and compared both the coverage and electrical characteristics with that formed by conventional plasma-enhanced chemical vapor deposition (PE-CVD) at 200°C. Furthermore, we analyzed these SiO2liners by FTIR and synchrotron XPS. These results showed that the OER-TEOS-CVD® has high potentials to realize highly-reliable TSVs and to apply to various processes in 3D integration.
