Abstract

A method is provided for connecting two conductive layers in an electronic circuit package comprising the steps of forming dendrites on selected regions of a first conductive layer, forming dendrites on selected regions of a second conductive layer, applying an epoxy adhesive material over the first conductive layer, and compressively attaching the second conductive layer to the first conductive layer such that the dendrites on the first conductive layer contact the dendrites on the second conductive layer. Also claimed is an electronic circuit package incorporating the dendrites used for electrical interconnection manufactured in accordance with the present invention. An alternative embodiment of the invention utilizes an intermediate surface metal with dendrites in place of a “through via.”
