Method for fabricating a stack of two dimensional circuit modules

摘要

A method for fabricating a stack of circuit modules includes providing a plurality of substrates having module interconnection layers. Each of the substrates has a circuit chip with chip pads positioned therein and an electrically conductive feed-through line extending from a first surface of the substrate to a second surface of the substrate with the first surface being perpendicular to the second surface. Each of the module interconnection layers is situated over a respective first surface of each of the substrates and includes a module dielectric layer having module vias therein and a module pattern of electrical conductors extending through the module vias to couple the selected chip pads to the feed-through line. The plurality of substrates are stacked. A side interconnection layer is applied over a side surface including the second surfaces of the substrates. The side interconnection layer includes a side dielectric layer having side vias therein aligned with predetermined ones of the feed-through lines and a side pattern of electrical conductors extending through the side vias.
