Coping and Living with Cervical Cancer,, better performance of the scaled circuits, and thinner gate material need better dielectric materials other than silicon dioxide (SiO.). As a result, copper has replaced Al-interconnect and low. interlayer and high. gate dielectric materials have replaced SiO.. Deep submicron copper interconnects

TVET and Ecologism: Charting New Terrained capacitive reactance of the interconnecting lines. The conductivity of copper (σ. = 0.598 ohm-cm and σ . = 0.374 ohm-cm) is higher and it offers higher resistance to electromigration (EM) compared to aluminum (or Al-alloy). At the same time, copper has the advantage of making finer wires with low
