摘要： Methods of resputtering material from the wafer surface include at least one operation of resputtering material under a pressure of at least 10 mTorr. The methods can be used in conjunction with an iPVD apparatus, such as hollow cathode magnetron (HCM) or planar magnetron. The resputtered material may be a diffusion barrier material or a conductive layer material. The methods provide process conditions which minimize the damage to the dielectric layer during resputtering. The methods allow considerable etching of the diffusion barrier material at the via bottom, while not damaging exposed dielectric elsewhere on the wafer. Specifically, they provide a solution for the dielectric microtrenching problem occurring during conventional resputter process. Furthermore, the methods increase the etch rate to deposition rate ratio (E/D) and improve the etch back nonuniformity (EBNU) of resputter process. In general, the methods provide IC devices with higher reliability and decrease wafer manufacturing costs.
摘要翻译：从晶片表面重新溅射材料的方法包括在至少10mTorr的压力下重新溅射材料的至少一种操作。该方法可以与iPVD装置结合使用，例如空心阴极磁控管（HCM）或平面磁控管。所述重排材料可以是扩散阻挡材料或导电层材料。该方法提供了在再溅射期间最小化对电介质层的损伤的工艺条件。这些方法允许在通孔底部对扩散阻挡材料进行相当大的蚀刻，同时不损坏晶片上其他地方的暴露的电介质。具体地说，它们提供了在常规的再溅射过程中发生的介电微切削问题的解决方案。此外，这些方法将蚀刻速率提高到沉积速率比（E / D），并提高了回溅过程的回蚀不均匀性（EBNU）。通常，这些方法为IC器件提供了更高的可靠性并降低了晶片制造成本。
