Abstract(in English) | A new TiN/Ti contact plug technology for Gigabit-scale DRAM was developed by use of Ti plasma-enhanced chemical vapor deposition (PECVD) and TiN low-pressure chemical vapor deposition (LPCVD). When PECVD-Ti film was deposited at greater than 545℃, in-situ Ti silicidation occurred on Si. The step coverage of LPCVD-TiN film was 100% in fine contact up to the aspect ratio of 7. By using this technology, low contact resistances and junction leakage currents were obtained for 0.25 μm contact holes with aspect ratio of 6. |
