Back grinding tape |
| abstract |
The present invention includes a polymer resin layer containing a urethane (meth) acrylate resin containing 10 to 40% by weight of a repeating unit derived from a (meth) acrylate monomer or oligomer having a glass transition temperature of 0 ° C. or higher. The present invention relates to a method for grinding a wafer using a back grinding tape and a back grinding tape in which the glass transition temperature of the polymer resin layer is −30 ° C. to 0 ° C. |
