Abstract:
A substrate processing apparatus constructed to process a substrate by supplying a processing solution to said substrate while rotating the same, comprising:a proximity suction part constructed to inject gas between an upper surface of said substrate and a supporting surface of said proximity suction part from a hole provided on said supporting surface opposed to the upper surface of said substrate thereby sucking said substrate through the Bernoulli effect; a rotation part rotating said proximity suction part about a vertical axis; a support member uprightly provided on said supporting surface of said proximity suction part for contacting with a peripheral upper surface of said substrate in a manner enabling transmitting a rotational driving force of said rotation part to said substrate when said proximity suction part contacts said substrate; and a processing solution supply part supplying a processing solution to a lower surface of said substrate rotated in contact with said support member.
