ABSTRACT:
The process of the present invention allows interconnecting one conductive layer to another in a Multichip Module. The process uses bumps formed by wire bonding, or any other means of forming bumps of 0.002"-0.004" height with comparable diameter. These bumps create an opening through dielectric insulating layers, thereby allowing one conductive layer to be electrically connected to the next conductive layer.
