Abstract:
A method for generating a multi-chip module, said method comprising the steps of:procuring a dielectric sheet defining a surface; tensioning said dielectric sheet to provide a measure of rigidity to said surface thereof; applying to said surface of said dielectric sheet, in a predetermined pattern, one or more electrical conductors having a predetermined thickness; applying encapsulating material to said surface of said dielectric sheet in a thickness sufficient to encapsulate said electrical conductors to thereby generate a rigid substrate element; fabricating apertures in said rigid substrate element at predetermined locations at which chips are to be placed on said multi-chip module; placing chips on a second dielectric substrate at locations registered with said apertures, with electrical interconnects of said chips facing in a particular direction; affixing said rigid substrate element to said second dielectric sheet with said chips extending into said apertures; and applying a flexible multilayer dielectric interconnection sheet over at least said electrical interconnects of said chips, and making connections between at least some of the interconnects of said interconnection layer and some of said electrical interconnects of said chips.
