Estimates of this type assume an infinite parallel plate capacitor, then use standard "Gaussian pillbox" arguments. An example can be found on page 110 of this text. Note that only a capacitance ratio is relevant here. Effects due to fringe fields that do not intersect the stop layer tend to cancel our for such ratios.

    • The thickness range given is based on the direct experience of the authors with semiconductor manufacturers. However, one can also roughly estimate this range using the ITRS roadmap. Table 46a of the Interconnect section of the ITRS 2000 roadmap gives "pitch" and "via A/R" (aspect ratio) values for 1999 to the present. One can now assume these values are used in volume manufacturing. ILD thickness is then estimated as the pitch times the via A/R ESL is then roughly estimated as 5% of the ILD thickness.
