Tribological Effects of Brush Scrubbing in Post Chemical Mechanical Planarization Cleaning on Electrical Characteristics in Novel Non-porous Low-k Dielectric Fluorocarbon on Cu Interconnects

X. Wendy Gu、Takenao Nemoto、Yugo Tomita 等 6 位作者2011-05-01Japanese Journal of Applied Physics

Damage reduction during planarization is strongly required to avoid scratch generation and the variation in the electrical properties of low- k dielectrics leading to yield loss in an integrated circuit after the implementation of an ultralow- k dielectric in Cu damascene interconnects. An optimum process condition to…

Sandra Contreras、Mohammad S. Yalfani、F. Medina 等 4 位作者2011-05-01Water Science & Technology

A catalytic system for the generation of H2O2 from formic acid and oxygen at ambient conditions has been developed. Pd-supported catalysts (Pd/C, Pd/TiO2 and Pd/Al2O3) have been tested, showing that for bulk purposes Pd/Al2O3 is more favourable while for in-situ applications Pd/TiO2 seems to be preferable. However, wh…
