摘要: 用900℃15秒快速热退火使硅上钛膜在高纯NH3中同时形成TiNxOy/TiSi2双层结构.研究了TiNxOy作为Al的扩散势垒的有效性.结果表明,Al/TiNxOy/TiSi2/Si接触系统直至550℃在N2中烧结30分钟仍然具有良好的热稳定性.

关键词: 快速热退火, 钛硅化物, 扩散势垒

Abstract: A TiNxOy/TiSi2 bilayer structure is formed simultaneously for Ti film on Si by rapid thermal annealing at 900℃ for 15s in highly pure NH3. The effectiveness of TiNxOy as a diffusion barrier layer for Al has been studied. Eesults show that the Al/TiNxOy/TiSi2/Si contact system has good thermal stability, when Bintered in N2, up to 550℃ for 30min.

Key words: diffusion barrier, rapid thermal annealing, titanium silicide
