摘要： A method for manufacturing a polishing pad prevents slurry leaks and provides a pad that can be used to provide high optical detection accuracy. The method for manufacturing a polishing pad includes forming a groove for injecting a light-transmitting region forming material on the back surface of a polishing layer; injecting the light-transmitting region forming material into the groove and curing the material to form a light-transmitting region; and buffing the front surface of the polishing layer to expose the light-transmitting region on the front surface.
