发明名称 METHOD OF ELIMINATING BACK-END REROUTING IN BALL GRID ARRAY PACKAGING AND APPARATUS MADE FROM SAME
摘要 Disclosed is a method of ball grid array packaging, comprising the steps of providing a semiconductor die having a metal conductors thereon, covering said metal conductors with an insulative layer, etching through said insulative layer so as to provide one or more openings to said metal conductors, depositing a compliant material layer, etching through said compliant material layer so as to provide one or more openings to said metal conductors, depositing a substantially homogenous conductive layer, patterning said conductive layer so as to bring at least one of said metal conductors in electrical contact with one or more pads, each said pad comprising a portion of said conductive layer disposed upon said compliant material, and providing solder balls disposed upon said pads. Also disclosed is the apparatus made from the method.
