  • Patent number: 8052505
    Abstract: A wafer processing method for processing a wafer (20) having bumps (B) formed on a front surface (21) comprises the steps of: holding on a table (51), a bump region-conforming member (40) that has an outer shape conforming only to a bump region (25) where said bumps are formed in the wafer; forming a resin layer (29) by applying resin around the bump region-conforming member up to a thickness equal to or greater than that of the bump region-conforming member; grinding the bump region-conforming member along with the resin layer to a predetermined thickness; removing the bump region-conforming member from the table to form a concave part (45) in the resin layer; applying a film (11) on the front surface of the wafer; and disposing the wafer in the concave part of the resin layer and holding the wafer on the table so that a back surface (22) of said wafer faces upward. After that, the back surface of the wafer can also be ground.

  • Publication number: 20110269381
    Abstract: For complex CMP processes requiring the removal of different dielectric materials, possibly in the presence of a polysilicon material, a slurry material may be adapted at the point of use by selecting an appropriate pH value and avoiding agglomeration of the abrasive particles. The in situ preparation of the slurry material may also enable a highly dynamic adaptation of the removal conditions, for instance when exposing the polysilicon material of gate electrode structures in replacement gate approaches.

  • Publication number: 20110237163
    Abstract: A substrate polishing apparatus includes a substrate holding mechanism having a head for holding a substrate to be polished, and a polishing mechanism including a polishing table with a polishing pad mounted thereon. The substrate held by the head is pressed against the polishing pad on the polishing table to polish the substrate by relative movement of the substrate and the polishing pad. The substrate polishing apparatus also includes a substrate transfer mechanism for delivering the substrate to be polished to the head and receiving the polished substrate. The substrate transfer mechanism includes a substrate to-be-polished receiver for receiving the substrate to be polished, and a polished substrate receiver for receiving the substrate which has been polished.

  • Patent number: 8025553
    Abstract: A back grinding method for a wafer includes covering a face-side surface of the wafer with a resin film, and cutting the surface of the resin film to form a flat surface parallel to the face-side surface of the wafer. The wafer is held with the surface of the resin film in contact with a suction surface of a chuck table in a grinding apparatus, and the exposed back-side surface of the wafer is ground. Unevenness in thickness of the resin film is suppressed, whereby the thickness of the wafer subjected to back grinding is made to be uniform.
