Abstract
Improved values for the resistivity, ?, of pure, bulk copper from 50 K to 1200 K, and their confidence intervals, are developed by extending the analysis of Matula. A recommended value for d?/dT and its confidence interval in the temperature range of 290 K to 425 K is developed for use with Matthiessen's rule to calculate the electrical thickness of thin copper films and the cross-sectional area of copper lines from resistance measurements at two temperatures. Error analyses are used to estimate the uncertainty with which the electrical thickness and cross-sectional area can be determined. Values for the temperature coefficient of resistance of pure, bulk copper are also provided.Citation
