Abstract:
A method of flowing a material into a portion of a semiconductor device assembly having a semiconductor die having a first surface and a second active surface having connectors thereon to a substrate having a first surface pattern of electrical circuits for contacting with said connectors of said semiconductor die, said substrate having an exterior surface spaced from said first surface pattern of electrical circuits and a plurality of vias extending through said first surface pattern of electrical circuits to said exterior surface, said method of connecting using a source of pressure and vacuum in a chamber comprising:connecting said connectors of said semiconductor die to a portion of said substrate having said connectors contacting a portion of the first surface pattern of electrical circuits of said substrate, said connectors forming a gap having a perimeter; placing fill material proximate the perimeter of said gap; and actuating said source of vacuum and said source of pressure for urging said fill material into said gap using said vacuum through one via of said plurality of vias and said pressure about said perimeter.
