摘要

Dynamic SIMS is an established tool for the characterization of dielectric layers in semiconductors, both for contaminant levels and for composition. As the silicon-based semiconductor industry moves towards the use of copper rather than aluminum, there is also a need to use lower k-dielectric materials to reduce RC delays and to reduce cross-talk between closely spaced metal lines. New dielectric materials pose serious challenges for implementation into semiconductor processes and also for the analytical scientist doing measurements on them.
