Abstract:
A method for polishing the surface of a semiconductor device substrate, comprising the steps of:providing a substrate having a thin film on the surface thereof; holding the back surface of said substrate with a substrate-holding carrier installed in a polishing equipment; and polishing said substrate so that the reaction force to said substrate generated when said substrate is pushed against an inner guide provided so as to surround said substrate for preventing said substrate from deviating from said carrier due to a friction force generated by the relative movement between said substrate and a polishing member provided on said polishing equipment, is dispersed, when said substrate is rotated while being integrated with said carrier while holding said substrate, and pushing said substrate against said polishing member provided in said polishing equipment, wherein an outer guide is provided outside of the inner guide in said carrier for keeping said carrier at a distance from said polishing member.
