摘要
The present invention generally relates to methods and apparatus for thermally processing substrates. The apparatus include an energy source, a plurality of chambers, and one or more energy switches. The one or more optical switches are adapted to direct an amount of energy emitted from the energy source to one of the plurality of chambers, and then change switch positions to direct the energy to a second of the plurality of chambers at a preselected time. The plurality of chambers may each include a heated support and a plurality of lamps therein to heat a substrate. The methods generally include thermally processing a first substrate in a first chamber while preheating or aligning a second substrate in a second chamber. After the first substrate is thermally processed, the second substrate is processed in the second chamber using the same energy source as was used to process the first substrate.
