Abstract:
A method of packaging a semiconductor substrate comprising the steps of:forming holes in a glass sheet, wherein the holes correspond to the location of bond pads disposed on a surface of a semiconductor substrate; depositing a first layer of conductive material on the surface of the glass sheet; etching the first layer of conductive material to form metallized pads on the surface of the glass sheet adjacent to the holes in the glass sheet; depositing adhesive on the surface of the semiconductor substrate; affixing the glass sheet to the semiconductor substrate utilizing the adhesive such that the holes in the glass sheet are aligned to match the location of the bond pads on the semiconductor substrate; etching the adhesive such that the adhesive is removed from the bond pads on a surface of the semiconductor substrate; depositing a second layer of conductive material on the surface of the glass sheet; etching the second layer of conductive material to create conductive traces that electrically connect the metallized pads through the holes in the glass sheet to the bond pads on the semiconductor substrate; and forming solder balls on the metallized pads.
