Patent application numberDescriptionPublished
20090139662SEPARATING DEVICE - A separating device according to the present invention separates a support plate (06-04-2009
20090218050Treatment liquid permeation unit and treating apparatus - A treatment liquid permeation unit (09-03-2009
20090314430Separating apparatus and separating method - A separating apparatus according to the present invention includes a clamp for gripping an outer peripheral end of a supporting plate. The clamp grips the outer peripheral end of the supporting plate and separates the supporting plate from a wafer by gripping the supporting plate. This makes it possible to separate a supporting plate from a wafer without breaking the wafer. With this, a supporting plate can be separated from a wafer to which the supporting plate has been attached, without breaking the wafer.12-24-2009
20090314438Supporting plate peeling apparatus - A supporting plate peeling apparatus in accordance with the present invention has removal means for removing an adhesive agent remaining on a side of a wafer from which a supporting plate has been peeled off, which adhesive agent is removed after (i) a supporting plate which supports a wafer reduced in thickness has been peeled off from the wafer and (ii) the side from which the supporting plate has been peeled off is washed with a washing liquid. The supporting plate peeling apparatus in accordance with the present invention is a supporting plate peeling apparatus which can remove the adhesive agent that remains on the side of the wafer from which the supporting plate has been peeled off that could not be completely removed just by the washing liquid, and which allows satisfactory completion of a peeling step. Hence, a supporting plate peeling apparatus is provided, which peels off a supporting plate for supporting a wafer, while not causing the side of the wafer from which the support plate has been peeled off to deteriorate.12-24-2009
20100000680SEPARATING APPARATUS AND SEPARATING METHOD - A separating apparatus according to the present invention includes a sucking plate for sticking to a support plate by suction. The sucking plate has sucking holes 01-07-2010
20100319209ALIGNMENT APPARATUS AND ALIGNMENT METHOD - Provided is an alignment apparatus including holding and rotating means for holding an alignment object and rotating the alignment object, the alignment apparatus including supporting means for supporting that part of the alignment object being rotated which is different from that part of the alignment object which is held by the holding and rotating means. This makes it possible to align the alignment object highly accurately by preventing the alignment object from being deformed, e.g. bent, due to its own weight.12-23-2010
20110259527STRIPPING DEVICE AND STRIPPING METHOD - A stripping method for stripping a support plate from a laminate including a substrate and the support plate adhered to the wafer via an adhesive layer, in which the adhesive layer is formed from an adhesive compound soluble in a non-polar solvent or a highly polar solvent; and the stripping method includes the step of supplying the non-polar solvent or the highly polar solvent, so that the non-polar solvent or the highly polar solvent is retained at least on an edge portion of that surface of the laminate which faces the support plate, and on a lateral surface of the laminate.10-27-2011

20090218460Sucking and holding device - A sucking and holding device includes: a vacuum chuck for vacuum-sucking a substrate; and a suction assisting device for sandwiching the object between it and the vacuum chuck. The suction assisting device includes a substrate-facing surface. The substrate-facing surface seals a through hole provided in the substrate. With this configuration, the sucking and holding device can vacuum-suck and hold the substrate having a through hole. This leads to an accomplishment of a device which can hold various objects without positional displacement.09-03-2009
