Patent ID: 8575030

Claim:
A semiconductor device manufacturing method comprising: polishing a film on a semiconductor substrate by pressing the film against a polishing pad which rotates in a predetermined direction, wherein polishing the film to be processed comprises performing a first polishing in which an entrance temperature of the polishing pad is adjusted to be equal to or higher than 40° C. and be equal to or lower than 50° C., and an exit temperature of the polishing pad is adjusted to be higher by 5° C. or more than the entrance temperature, the entrance temperature being a temperature of a surface of the polishing pad on an upstream side in the rotational direction of the polishing pad from the film pressed on the polishing pad, and the exit temperature being a temperature of a surface of the polishing pad on a downstream side in the rotational direction of the polishing pad from the film pressed on the polishing pad, and performing a second polishing in which the entrance temperature is adjusted to be equal to or lower than 30° C., and the exit temperature is adjusted to be higher by 5° C. or more than the entrance temperature.
