本文研究了H_2还原WF_6在α-Si/TiN/Al和TiW/Al衬底上LPCVD生长钨膜的特性。测量和分析了Al/W/TiN/Al和Al/W/TiW/Al结构的接触电阻和界面特性,研究了两种结构的热稳定性。结果表明,H_2还原WF_6可以在α-Si/TiN/Al和TiW/Al衬底上实现选择性钨淀积,钨膜质量较好。Al/W/TiN/Al和Al/W/TiW/Al结构接触电阻率为10~(-?)Ωcm~2量级,远低于难熔金属硅化物同硅的欧姆接触电阻率。两种结构的热稳定性良好。采用TiN或TiW作为Al和W之间的隔离层,CVD-W填充互连层连通孔可以满足多层金属平坦化互连技术的要求。 相似文献

Using X-ray structural analysis, scanning electron microscopy, atomic force microscopy, and photoluminescent spectroscopy,
it is shown that it is possible to obtain a small-scale domain structure on the surface of liquid-phase epitaxial heterostructures.
The domain structure emerges as a result of spinodal decomposition of the Ga
