  • Publication number: 20070125491
    Abstract: Particles attached to the back surface of a substrate are removed easily, reliably and quickly. An adhesive sheet is placed with an adhesive portion thereof up on a support base, and a substrate is placed thereon. Thereafter, the air pressure on the back surface side of the substrate is reduced lower than the air pressure on the front surface side to allow the adhesive sheet and the substrate to firmly adhere to each other. Then, the pressure difference is removed, and an elevating pin lifts the substrate from below the support base through a hole formed in each of the support base and the adhesive sheet to strip off the substrate from the adhesive sheet. Accordingly, the particles on the back surface of the substrate can be removed quickly, reliably and easily.

  • Patent number: RE40502
    Abstract: A plasma display panel has a good productivity of partition formation and air exhaustion process and realizes a bright and stable display. A discharge gas is filled in a gap between two substrates. A mesh-patterned partition is arranged on the inner surface of one of the substrates for dividing the gap into plural squares corresponding to a cell arrangement. The partition has low portions forming a mesh-like air path that travels through all of the gas-filled space enclosed by the partition, in a plan view. A plasma display panel includes two spaced substrates defining a gap therebetween. The gap is divided by intersecting walls into columns and rows of discharge cells. Portions of a wall that are lower in height than remaining portions of the wall define a flow path. The plasma display panel realizes a bright and stable display.
