  • Patent number: 10985108
    Abstract: Provided herein are conductive formulations which are useful for applying conductive material to a suitable substrate; the resulting coated articles have improved EMI shielding performance relative to articles coated with prior art formulations employing prior art methods. In accordance with certain aspects of the present invention, there are also provided methods for filling a gap in an electronic package to achieve electromagnetic interference (EMI) shielding thereof, as well as the resulting articles shielded thereby. Specifically, invention methods utilize capillary flow to substantially fill any gaps in the coating on the surface of an electronic package. Effective EMI shielding has been demonstrated with very thin coating thickness.

  • Patent number: 9230888
    Abstract: A semiconductor assembly comprises a semiconductor wafer, an adhesive coating disposed on the back side of the wafer, and a bare dicing tape, preferably UV radiation transparent. The assembly is prepared by the method comprising (a) providing a semiconductor wafer, (b) disposing a wafer back side coating on the semiconductor wafer, (c) partially curing the wafer back side coating to the extent that it adheres to the back side of the wafer and remains tacky, and (d) contacting the bare dicing tape to the partially cured and tacky wafer back side coating, optionally with heat and pressure.
