Abstract
A method for mounting a semiconductor wafer on a polishing block to hold the semiconductor wafer during polishing. The method comprises the steps of providing a polishing block having a surface for mounting the semiconductor wafer, coating the polishing block surface with a bonding agent, applying radiant heat to the polishing block and bonding agent to soften the bonding agent, and applying the semiconductor wafer to the softened bonding agent. The step of applying radiant heat to the polishing block and bonding agent is performed by a radiant heater in a dry environment.
