Disclosed is a substrate rotating and oscillating apparatus for a rapid thermal process (RTP), that oscillates an oscillation plate using an oscillation motor moved by an elevating unit. Rotational shafts of the oscillation motor comprise lower and upper center rotational shafts mounted on a central axis of the motor, and an eccentric shaft mounted between the lower and the upper center rotational shafts as deviated from the central axis. An oscillation cam is mounted to the eccentric cam. The oscillation plate has an oscillation hole for inserting the oscillation cam therein. A bearing is mounted between the oscillation cam and the eccentric shaft such that the oscillation cam rotates independently from the eccentric shaft. The oscillation plate supports the whole multipole-magnetized magnetic motor or maglev motor. Accordingly, the substrate can be uniformly heated by both rotating and all-directionally oscillating the substrate.
