Abstract:
1. A substrate rotating and oscillating apparatus for a rapid thermal process (RTP), comprising a substrate rotating unit connected to a substrate supporter which supports a substrate so as to rotate the substrate by rotating the substrate supporter; an oscillation plate that supports the substrate rotating unit; and a substrate oscillating unit that oscillates the substrate by horizontally oscillating the oscillation plate, wherein the substrate rotating unit comprises: an oscillation motor of which rotational shafts comprise a lower center rotational shaft, an eccentric shaft, and an upper center rotational shaft, the lower and the upper center rotational shafts mounted on a central axis of the motor and the eccentric shaft mounted between the lower and the upper center rotational shafts to be deviated from the central axis; an elevating unit moving the oscillation motor up and down; an oscillation cam mounted to the eccentric cam; and the oscillation plate having an oscillation hole for inserting the oscillation cam therein.
