Abstract
A porous substrate curtain coated with a single coating of a liquid dielectric that is cured into a well adhering film at least 15 microns thick with a uniformity of less than 5 microns. The substrate is cleaned to remove contaminants, heated to remove moisture, curtain coated with a single coating of a viscous heat curable liquid dielectric such as polyimide, and heated to cure the dielectric by increasing the temperature at most 15.degree. C. per minute to a predetermined cure temperature not exceeding 450.degree. C. The invention is well suited for fabricating a dielectric layer in a high density multichip module.
