Classification: CPC B  H | IPC B  H

Claim 13:
14. A substrate processing method of thinning a substrate, the substrate processing method comprising:
grinding, by using a grinder, the substrate held by a substrate holder,
wherein, in the grinding of the substrate, the substrate is ground by bringing the grinder into contact with the substrate while rotating the substrate held by the substrate holder by a rotation shaft connected to the substrate holder in a state that the rotation shaft is tilted,
a rotation driving force for rotating the substrate holder is applied by a driving device provided independently from the rotation shaft, and
the rotation driving force of the driving device is delivered to the rotation shaft by a driving force transmitter, and the driving force transmitter is configured not to deliver an inclination of the rotation shaft to the driving device,
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 in the grinding of the substrate, 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.
