Apparatus and method for removing a film from a surface

After molding a substrate located between first and second molds of a molding system, a used release film that is in contact with the substrate during molding is removed from the molding system with a gripper assembly, which is reciprocally movable between a retracted position outside the molding system and an extended position in a space between the first and second molds when the first and second molds are opened. A carriage mechanism on which the gripper assembly is mounted moves the gripper assembly towards the first or second mold until the gripper assembly contacts the used release film, before an actuator actuates the gripper assembly to clamp onto a part of the used release film. The carriage mechanism also conveys the gripper assembly away from the first mold or second mold to remove the used release film from the molding system.

Separation apparatus, separation system, and separation method

A separation apparatus for separating a superposed substrate in which a processing target substrate and a supporting substrate are joined together with an adhesive, into the processing target substrate and the supporting substrate includes: a first holding unit that includes a heating mechanism heating the processing target substrate and holds the processing target substrate; a second holding unit that includes a heating mechanism heating the supporting substrate and holds the supporting substrate; a moving mechanism that relatively moves at least the first holding unit or the second holding unit in a horizontal direction; and a porous part that is annularly provided along an outer peripheral portion of the first holding unit and formed with a plurality of pores, and supplies an inert gas to the outer peripheral portion of the first holding unit holding the processing target substrate.

High-temperature, spin-on, bonding compositions for temporary wafer bonding using sliding approach

New compositions and methods of using those compositions as bonding compositions are provided. The compositions comprise a polymer dispersed or dissolved in a solvent system, and can be used to bond an active wafer to a carrier wafer or substrate to assist in protecting the active wafer and its active sites during subsequent processing and handling. The compositions form bonding layers that are chemically and thermally resistant, but that can also be softened to allow the wafers to slide apart at the appropriate stage in the fabrication process.

Adhesive-film exfoliating device and manufacturing method of liquid crystal display panel using the device

An adhesive-film exfoliating device includes an absorption stage 6 for absorbing a liquid crystal display panel 4 in which a polarizing plate 3 is adhered to a glass plate 2, a clamping unit 7 for clamping a corner 3a of the polarizing plate 3 exfoliated from the glass plate 2 and a ball screw shaft 11 for moving the absorption stage 6 relatively to the clamping unit 7. A ball screw nut 14 in screw-engagement with the ball screw shaft 11 is fixed on a back surface of the absorption stage 6. With the rotation of the ball screw shaft 11, the absorption stage 6 integral with the ball screw nut 14 is slid in a direction to exfoliate the polarizing plate 3 exfoliated from the glass plate 2. In a manufacturing method of the liquid crystal display panel 4, a process of exfoliating the polarizing plate 3 from the glass plate 2 includes steps of moving the absorption stage 6 while allowing the clamping unit 7 to clamp the corner 3a of the polarizing plate 3.

Prepreg debacker and method of layup

A method of removing backing film from a sheet element is provided. The sheet element has a preimpregnated layer, and sheets of backing film are adhered to the top and bottom of the preimpregnated layer. The backing film has a different coefficient of thermal expansion than the preimpregnated layer, and a plane of the sheet element is defined by the peripheral edge. A shear strain is created between the backing films and the preimpregnated layer by cooling the sheet element. A fluid stream is directed at a portion of the peripheral edge, the fluid stream being directed in the plane of the sheet element. The fluid stream causes the backing films to separate from the top and bottom of the preimpregnated layer. A differential pressure is simultaneously applied to the backing films relative to the fluid stream to cause the backing films to be removed from the preimpregnated layer.

Method of making post-bonded grooved elastic materials

An elastic nonwoven laminate that contains an elastic film laminated to one or more nonwoven facings is provided. The nonwoven facing contains a conventional polyolefin and can also contain a polyolefin-based plastomer. The laminate is activated by grooving to decouple the nonwoven facing from the elastic film. To reduce fiber-pull out that can result due to activation by grooving, the laminate can be post-bonded at room or elevated temperatures and a specific range of pressures to compact the fibers of the facing and minimize fiber pull-out/fuzziness while not sacrificing the softness, elasticity, and feel of the laminate.
