20090017248 | LAYERED BODY AND METHOD FOR MANUFACTURING THIN SUBSTRATE USING THE LAYERED BODY - Provided is a layered body including a substrate to be ground and a support, where the substrate may be ground to a very small (thin) thickness and can then be separated from the support without damaging the substrate. One embodiment is a layered body including a substrate to be ground, a joining layer having a curable acrylate polymer and a curable acrylate adhesion modifying agent in contact with the substrate to be ground, a photothermal conversion layer having a light absorbing agent and a heat decomposable resin, and a light transmitting support. After grinding the substrate surface which is opposite that in contact with the joining layer, the layered body is irradiated through the light transmitting layer and the photothermal conversion layer decomposes to separate the substrate and the light transmitting support. | 01-15-2009 |
