Abstract: Methods for releasing a device substrate temporarily bonded by a bonding layer to a carrier substrate. A dissolution head is engaged with the carrier substrate and a first dissolution process is performed to partially remove the bonding layer. After the first dissolution process is completed, the dissolution head is disengaged from the carrier substrate, and then re-engaged with the carrier substrate. In response to re-engaging the dissolution head with the carrier substrate, a second dissolution process is performed to further remove the bonding layer remaining after the first dissolution process.
Abstract: A silicon substrate 12 has a main face in a (100) plane, whereby a fracture 17 generated from a molten processed region 13 acting as a start point extends in a cleavage direction of the silicon substrate 12 (a direction orthogonal to the main face of the silicon substrate 12). Here, a rear face 1b of an object to be processed 1A and a front face 10a of an object to be processed for separation 10A are bonded to each other by anode bonding, whereby the fracture 17 reaches a front face 1a of the object 1A continuously without substantially changing its direction. When generating a stress in the object for separation 10A, the fracture 17 has reached a rear face 10b of the object for separation 10A and thus easily extends toward the object 1A.

Abstract: Described methods and apparatus provide a controlled perturbation to an adhesive bond between a device wafer and a carrier wafer. The controlled perturbation, which can be mechanical, chemical, thermal, or radiative, facilitates the separation of the two wafers without damaging the device wafer. The controlled perturbation initiates a crack either within the adhesive joining the two wafers, at an interface within the adhesive layer (such as between a release layer and the adhesive), or at a wafer/adhesive interface. The crack can then be propagated using any of the foregoing methods, or combinations thereof, used to initiate the crack.

Abstract: A process and method for recycling carpet is disclosed. The process and method involves the liberation and separation of desirable carpet face fibers from the carpet backing materials. The present invention eliminates face fiber shearing. In the present process, the secondary layer of the carpet backing is removed either manually or mechanically. Then, the bottom of the primary backing layer of the carpet with the bottom of the face fiber “U's” exposed, is mechanically grip-abraded by a rubber material. The grip-abrasion of the rubber or rubber-like material across the bottom of the primary carpet backing layer loosens the glue and grips and pulls the face fiber from the primary backing without destructing primary or secondary backing. The liberation and separation of face fibers from the backing materials using this method produces the highest yield of usable materials compared to any other method.
