摘要： Provided is a substrate for processing a wafer. The present invention can provide a substrate having excellent heat resistance and dimensional stability. The present invention can provide a substrate that has excellent stress relaxation properties, and therefore can prevent a wafer from being destroyed due to residual stress. Also, the present invention can provide a substrate that can prevent a wafer from being damaged or fried off due to a non-uniformly applied pressure during the wafer processing process, and that exhibits excellent cuttability. For these reasons, the substrate can be useful as a sheet for processing a wafer in various wafer preparation processes such as dicing, back-grinding, and picking-up.

摘要： An electrode assembly and a battery are provided. The electrode assembly may be effectively fixed inside a can as a pressure-sensitive adhesive tape attached to an outer circumferential surface of the electrode assembly is formed into a 3D shape by an electrolyte. Thus, the electrode assembly does not move and rotate inside the can due to external vibration or impact and damage of welded regions of a tab or disconnection of inner circuits can be prevented.
