摘要:
Low-frequency noise measurements were performed on thin metallic very large-scale integration (VLSI) interconnects of three different geometries. These measurements were carried out under stressing current densities between 1.0 x 10(5) A/cm(2) and 2.2 x 10(6) A/cm(2) at different ambient temperatures up to 280degreesC, in order to investigate the dependence of low-frequency noise on the geometrical shape of the VLSI interconnects. The behavior of these samples under these conditions is analyzed in this letter.
