Résumé
This paper deals with propagation delay, rise time and crosstalk for Cu wire of 100 nm width and 2.2 to 1.7 aspect ratio AR ( AR /spl sime/ h/w) in single and coupled configuration. Electrical and electromagnetical characteristics are predicted, with a full wave analysis, for various wire resistivity and low k dielectric material when a clock pulse of 143 ps period (7 GHz) propagate. Critical value of 300 /spl mu/m is calculated for wire length when propagation delay equals MOSFET switching delay. Such critical values also induced more than 20% crosstalk in two coupled lines with 100 nm spacing and low k=2.0.
