Abstract:
1. A method for the thermal treatment of a planar substrate, comprising: providing a reactor having one or more furnace bodies, the one or more furnace bodies each having a substantially flat boundary surface; heating the one or more furnace bodies to a predetermined furnace body temperature; placing the substrate adjacent to and essentially parallel to the one or more furnace bodies such that a planar surface of the substrate faces the boundary surface of each of the one or more furnace bodies; keeping the substrate adjacent to the boundary surface of each of the one or more furnace bodies during a heat-up time to allow the substrate to heat up to a substrate temperature, wherein the substrate temperature is less than the furnace body temperature of each of the one or more furnace bodies by about 20° C. or more; and subsequently removing the substrate from the reactor while the substrate temperature is still less than the furnace body temperature of each of the one or more furnace bodies by about 20° C. or more.
