Newtonian Limit for Viscosity Measurements of KMER Photoresist Solutions.
Abstract
Rapid measurements of the viscosity of photoresist solutions, that are being performed as part of process control in integrated circuit technology, are usually based on methods, such as the Ostwald-Cannon-Fenske viscometer, which apply only to Newtonian liquids. The present investigation was, therefore, designed to determine the range of dilutions for Kodak Metal-Etch Resist for which the solution becomes non-Newtonian. The results presented indicate that non-Newtonian behavior occurs only at mixtures with thinner concentrations above 10 percent, and that for most photoresist applications, non-Newtonian behavior need not be considered.
