Classification: CPC B  H | IPC B  H

Claim 0:
1. A substrate processing system configured to thin a substrate, the substrate processing system comprising:
a substrate holder configured to hold the substrate;
a grinder configured to perform a grinding of the substrate held by the substrate holder;
a rotation shaft connected to the substrate holder and configured to rotate the substrate holder;
a driving device provided independently from the rotation shaft and configured to apply a rotational driving force for rotating the substrate holder; and
a driving force transmitter configured to deliver the rotational driving force of the driving device to the rotation shaft and configured not to deliver an inclination of the rotation shaft to the driving device,
wherein the substrate is ground by bringing the grinder into contact with the substrate in a state that the rotation shaft is tilted,
wherein the driving force transmitter comprises:
a first driving force transmitter provided at a side of the rotation shaft; and
a second driving force transmitter provided at a side of the driving device,

wherein a hollow portion is formed between the first driving force transmitter and the second driving force transmitter, and
wherein the substrate is ground by bringing the grinder into contact with the substrate in a state that the first driving force transmitter is tilted in the hollow portion.
