Abstract
Described herein are interconnected mutilayer boards and their fabrication processes. Multilayer conductor lines of a skeleton structure are formed by conducting multilayer metallization while including all resist layers and metallic under-conductive layers and then removing the resist layers and metallic under-conductive layers at once. Spaces between the multilayer conductor lines of the skeleton structure are then filled with a solventless varnish so that insulating layers are formed. Modules making use of such interconnected multilayer boards and computers having such modules are also described.
