摘要： A pressure sensitive adhesive sheet according to the present invention is a resin laminate, including a high thermally shrinkable base layer having relatively high thermal shrinkage ratio, having a ratio (A:B) of the thermal shrinkage ratio in a main shrinkage direction [A (%)] to the shrinkage ratio in a direction perpendicular to the main shrinkage direction [B (%)] of 1:1 to 10:1, and a low thermally shrinkable base layer having relatively low thermal shrinkage ratio, the high and low thermally shrinkable base layers bonded to each other via a self-adhesive layer, wherein the resin laminate bends toward the high thermally shrinkable base layer side when heated from any one direction and can automatically curl from one terminal unidirectionally to form a tubular roll by further heating. The pressure sensitive adhesive sheet can be separated from an adherend smoothly when heated from any one direction. Thus, it can be used, for example, as a pressure sensitive adhesive sheet for semiconductor wafer polishing.

摘要： A cooling plate having a cooling pipe mounted therein in a serpentine shape is placed in a stack manner on a rear face of a chuck table for suction-holding a rear face of the semiconductor wafer. A coolant is circulated through the cooling pipe, thereby cooling the chuck table. The semiconductor wafer is suction-held while the chuck table is cooled. In addition, the protective tape is joined to the semiconductor wafer while the chuck table is cooled. That is, the protective tape is joined to the surface of the semiconductor wafer while being cooled indirectly via the semiconductor wafer cooled in advance through direct contact to the chuck table during joining of the protective tape.
