  • Patent number: 8034718
    Abstract: Disclosed are embodiments of a method of removing patterned circuit structures from the surface of a semiconductor wafer. The method embodiments comprise blasting the surface of the semiconductor wafer with particles so as to remove substantially all of the patterned circuit structures. The blasting process is followed by one or more grinding, polishing and/or cleaning processes to remove any remaining circuit structures, to remove any lattice damage and/or to achieve a desired smoothness across the surface of the semiconductor wafer.

  • Patent number: 7932614
    Abstract: A C4 grind tape and a laser-ablative adhesive layer are formed on a front side of a semiconductor substrate. A carrier substrate is thereafter attached to the laser-ablative adhesive layer. The back side of the semiconductor substrate is thinned by polishing or grinding, during which the carrier substrate provides mechanical support to enable thinning of the semiconductor substrate to a thickness of about 25 ?m. A film frame tape is attached to the back side of the thinned semiconductor substrate and the laser-ablative adhesive layer is ablated by laser, thereby dissociating the carrier substrate from the back side of the C4 grind tape. The assembly of the film frame tape, the thinned semiconductor substrate, and the C4 grind tape is diced. The C4 grind tape is irradiated by ultraviolet light to become less adhesive, and is subsequently removed.
