  • Abstract
    Electromigration behavior of dual damascene Cu interconnect has been investigated comparing PE-TEOS SiO 2 with fluorine doped SiO 2 (FSG). MTFs of FSG in both line and contact EM tests were significantly shorter than those of PE-TEOS. The higher compressive stress and fluorine of FSG dielectric are considered to affect the EM reliability performance of the confined Cu interconnect.
