Title:
ADHESIVE SHEET AND METHOD FOR USING THE SAME
Document Type and Number:
Japanese Patent JP2004256595
Kind Code:
A
Abstract:

To provide an adhesive sheet suitably used as a surface-protecting sheet which can sufficiently protect a semiconductor wafer, when or after the backside of the wafer is polished, does not shrink, even when a die-bonding sheet is thermo-compression-bonded to the polished backside, and can therefore minimize the deformation of the wafer.

This adhesive sheet comprising a substrate and an adhesive layer formed on the substrate is characterized by using a substrate having a shrinkage stress of ≤5.0×105 N/m2 measured when heated at 23 to 180°C, held at 180°C for one minute, and then cooled to 23°C, as the substrate.
