Claim 0:
1. A substrate processing apparatus comprising:
a conveyor belt on which a substrate is seated;
a polishing head which is connected to a driver and configured to face the substrate; and
in order between the substrate and the polishing head which faces the substrate:
a polishing pad having a temperature; and
a polishing pad fixing member which fixes the polishing head and the polishing pad to each other, directly receives heat from the polishing pad and has a temperature, the polishing pad fixing member extended in a plane between the polishing head and the polishing pad;
and

a temperature sensor which is adjacent to and spaced apart from the polishing pad fixing member, in the plane, the temperature sensor sensing the temperature of the polishing pad fixing member,
wherein the temperature of the polishing pad is defined by the sensed temperature of the polishing pad fixing member.
