Abstract
This invention comprises various high production methods for simultaneously forming surface metallizations on a plurality of monolithic electronic modules. Each monolithic electronic module may comprise a single semiconductor chip or multiple semiconductor chips. The methods can employ a workpiece which automatically discontinues side surface metallization between different electronic modules in the stack. Multiple workpieces are interleaved within the stack between the electronic modules. Each workpiece may include a transfer layer(s) for permanent bonding to an end surface of an adjacent electronic module in the stack. This transfer layer may comprise an insulation layer, a metallization layer, an active circuit layer, or any combination thereof. End surface metallization can thus be provided contemporaneous with side surface metallization of multiple electronic modules.
