Accuracy in Integrated Circuit Dimensional Measurements

December 1, 1994
Author(s)
James E. Potzick
The measurement of critical dimensions of features on integrated circuits and photomasks is modeled as the comparison of the images of the test object and of a standard object in a measuring device. A length measuring instrument is then a comparator. The

Burning Rate and Flame Heat Flux for PMMA in the Cone Calorimeter.

December 1, 1994
Author(s)
B T. Rhodes
Ignition and burning rate data are developed for thick (25 mm.) black Polycast PMMA in a Cone Calorimeter heating assembly. The objective is to establish a testing protocol that will lead to the prediction of ignition and burning rate from Cone data. This

Compensation for Substrate Permittivity in Probe-Tip Calibration

December 1, 1994
Author(s)
Dylan F. Williams, Roger Marks
We demonstrate a method of compensation for the effect of substrate permittivity on coplanar waveguide probe-tip scattering parameter calibrations, modeling the effect as a capacitance at the probe tip. Comparison to on-wafer multiline TRL calibration
