Fabrication and characterization of copper interconnects of line-width down to 100nm using a specially designed phase shift mask
Mask simulation: alternating-phase-shifted scatter bars provides better performance. A novel mask is designed to fabricate 100 and 150nm wide Cu interconnects. Integration process characterization: analytical tools are used extensively. Electrical characterization: very good results are obtained.
