ABSTRACT:
The invention is for the formation of multilayer circuit boards where layers are formed sequentially using selective plating techniques and photoimaging of permanent dielectric materials to achieve fine line resolution and interconnections between circuits. The invention permits the sequential formation of multilayers of higher density using photoimaging techniques.
