Abstract: The present invention generally relates to methods of cooling a substrate during rapid thermal processing. The methods generally include positioning a substrate in a chamber and applying heat to the substrate. After the temperature of the substrate is increased to a desired temperature, the substrate is rapidly cooled. Rapid cooling of the substrate is facilitated by increasing a flow rate of a gas through the chamber. Rapid cooling of the substrate is further facilitated by positioning the substrate in close proximity to a cooling plate. The cooling plate removes heat from substrate via conduction facilitated by gas located therebetween. The distance between the cooling plate and the substrate can be adjusted to create a turbulent gas flow therebetween, which further facilitates removal of heat from the substrate. After the substrate is sufficiently cooled, the substrate is removed from the chamber.
