  • Patent number: 9219044
    Abstract: Patterned photoresist is used to attach a carrier wafer to a silicon device wafer. In one example, a silicon wafer is patterned for contact bumps by applying a photoresist over a surface of the wafer and removing the photoresist in locations at which the contact bumps are to be formed. The contact bumps are formed in the locations at which the photoresist is removed. A temporary carrier is attached to the photoresist over the wafer. The back side of the wafer opposite the contact bumps is processed while handling the wafer using the temporary carrier. The temporary carrier is removed. The photoresist on the front side of the wafer with the contact bumps is removed after removing the temporary carrier.

  • Patent number: 9202801
    Abstract: Thin substrates and mold compound handling is described using an electrostatic-chucking carrier. In one example, a first part of a plurality of silicon chip packages is formed on a front side of a silicon substrate wafer at a first processing station. An a carrier wafer of an electrostatic chuck is attached over the front side of the silicon wafer. The substrate wafer is moved to a second processing station. A second part of the plurality of silicon chip packages are formed on a back side of the silicon wafer at a second processing station. The electrostatic chuck is then released.

  • Publication number: 20140264954
    Abstract: Embodiments of the invention generally relate to molded wafers having reduced warpage, bowing, and outgassing, and methods for forming the same. The molded wafers include a support layer of silicon nitride disposed on a surface thereof to facilitate rigidity and reduced outgassing. The silicon nitride layer may be formed on the molded wafer, for example, by plasma-enhanced chemical vapor deposition or hot-wire chemical vapor deposition.
