Hale, G. J.

The capability to deposit 10- to 12-..mu..m-thick aluminum films with less than 2 percent thickness uniformity (defined as standard deviation/average thickness) on large nonplanar and planar polyimide substrates has been developed using physical vapor deposition (PVD). A technique called shadow masking was developed to provide this consistent deposit uniformity over the entire substrate surfaces (greater than 2000 cm/sup 2/). The specific dimensions of a shadow mask for each substrate are generated from a computer-reduced plot of beta-backscatter thickness measurements of a previous deposit. With this developed method, initial thickness uniformities of 9.7 and 24.7 percent obtained for the nonplanar and planar deposits were improved to 1.07 and 1.80 percent, respectively.
