Abstract

A simple method for evaluating the geometrical parameters yielding maximum uniformity of film thickness on rotating substrates is described. The algorithm is based on numerical integration of the function for relative thickness. It is shown that maximum uniformity is obtained for a normalized source-to-substrate distance ratio of h/ \delta = 1.37.
