  • Apparatus and method for screening using electrostatic adhesion
    Patent number: 5891543
    Abstract: The present invention relates generally to a new apparatus and method for screening using electrostatic adhesion. More particularly, the invention encompasses an apparatus that uses an electrostatic charge during the screening process for a semiconductor substrate. Basically, a backing layer is adhered to a green ceramic sheet using an electrostatic charge, while the green ceramic sheet is processed.

  • Apparatus and method for screening green sheet with via hole using porous backing material
    Patent number: 5759669
    Abstract: The present invention relates generally to a new apparatus and method for screening using porous backing material. More particularly, the invention encompasses an apparatus that uses a porous backing material which is adhered to a green sheet during the screening process. Basically, a backing layer having a very high porosity is adhered to a green sheet, while the green sheet is screened. During the drying process of the green sheet some of the screening fluids are absorbed by the porous backing layer, which allows the screened vias of the green sheet to have a smooth surface.
