摘要
Unit processes now exist to plasma etch the main categories of possible interconnect low-k dielectrics. Integration challenges and trade-offs remain for all films, though all can be etched within a dual-damascene process flow. Controllability and cost of the integrated process will determine material choice, since unit processes are relatively similar.
