Disclosed is a device for treating a semiconductor substrate. The device comprises a rotational support plate in which at least one mounting recess is formed at the periphery thereof, and support blocks disposed on the periphery of the support plate within said mounting recess for supporting the semiconductor substrate. Each of the support blocks comprises a positioning portion on which the semiconductor substrate is positioned. An insertion portion which has a shape complementary to the shape of the mounting recess is disposed under the positioning portion where it is inserted into the mounting recess.
