Abstract
A system and method is disclosed for aligning an integrated circuit die on an integrated circuit substrate. A plurality of deposits of deformable material are placed on the substrate where the integrated circuit die is to be aligned. In one advantageous embodiment a stamping tool is indexed to a first tooling hole and to a second tooling hole in the substrate. The stamping tool imprints the deposits of deformable material to a tolerance of less than one hundred microns with respect to the first and second tooling holes. The imprinted portions of the deposits a form a pocket for receiving the integrated circuit die. This enables the integrated circuit die to be precisely aligned on the substrate in three dimensions.
