A method and device for detaching a first substrate, which is connected to a second substrate by an interconnect layer, from the second substrate by embrittlement of the interconnect layer. A method for bonding of a first substrate to a second substrate with an interconnect layer which can be embrittled by cooling. A use of a material which can be embrittled for producing an interconnect layer between first and second substrates for forming a substrate stack. A substrate stack, formed from a first substrate, a second substrate and an interconnect layer located therebetween, the interconnect layer formed from a material which can be embrittled. A wafer chuck for holding a first substrate when the first substrate is being detached from a second substrate with fixing means which can be activated by lowering the temperature.

Methods for separating a plurality of diamagnetic directed self-assembled diamagnetic components are provided. One method includes, for instance: contacting a release substrate to the plurality of diamagnetic components, the plurality of diamagnetic components including a non-diamagnetic component affixed to a diamagnetic portion by a first adhesive, and removing the release substrate, the non-diamagnetic component being affixed to a final substrate by a second adhesive and the release substrate being affixed to the diamagnetic portion by a third adhesive, and wherein the removing removes the diamagnetic portion and at least a portion of the first adhesive from the non-diamagnetic component.

A film peeling apparatus including a peeling unit, a peeling unit position adjusted, and a clamp. The peeling unit has uneven portions at an end portion thereof. The peeling unit is configured to peel off a protection film attached on a display panel. The peeling unit position adjuster is connected to the peeling unit. The peeling unit position adjuster is configured to adjust a position of the peeling unit. The clamp is disposed separately from the peeling unit. The clamp is configured to clamp the peeling unit.

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 which holds the processing target substrate; a second holding unit which holds the supporting substrate; a moving mechanism which relatively moves the first holding unit or the second holding unit in a horizontal direction; a load measurement unit which measures a load acting on the processing target substrate and the supporting substrate when the processing target substrate and the supporting substrate are separated; and a control unit which controls the moving mechanism based on the load measured by the load measurement unit.

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.

Methods, systems and devices to divide a layer of a first material from another material, to which is attached, are provided. Particularly, for the separation of the PVC from a modular carpet. By the use of a parallel blades mechanism that through an opposite counterpart apply at least a shear stress over the material of the modular carpet to tear the PVC layer and divide it. The carpet is preheated to facilitate the process of division and reuse of said PVC.

A method includes: a first step of disposing the superposed substrate at a position where the superposed substrate is not in contact with a first holding unit and a second holding unit in a space between the first holding unit and the second holding unit, and supplying an inert gas into the space; a second step of thereafter relatively moving the first holding unit and the second holding unit in the vertical direction, and holding the processing target substrate by the first holding unit and holding the supporting substrate by the second holding unit; and a third step of thereafter relatively moving the first holding unit and the second holding unit in the horizontal direction while heating the processing target substrate held by the first holding unit and the supporting substrate held by the second holding unit, to separate the processing target substrate and the supporting substrate from each other.

A peeling device for peeling off a substrate to be processed and a support substrate from an overlapped substrate, the overlapped substrate being formed by bonding the substrate to be processed and the support substrate by an adhesive, which includes: a first holding unit configured to heat the substrate to be processed and configured to hold the substrate to be processed; a second holding unit configured to heat the support substrate and configured to hold the support substrate; a moving mechanism configured to horizontally move at least one of the first holding unit and the second holding unit relative to each other; and an inert gas supply mechanism configured to supply an inert gas onto a bonding surface of the substrate to be processed or a bonding surface of the support substrate.
