Abstract:
A rapid thermal process reactor for processing a single substrate having a diameter selected from a group of diameters including 125 mm, 150 mm, 200 mm, 250 mm, and 300 mm diameters, said rapid thermal process reactor comprising:a rapid thermal process reaction chamber;a rotatable rapid thermal process susceptor mounted within the rapid thermal process reaction chamber, and having a first surface adapted for mounting said single substrate having a diameter selected from the group of diameters including 125 mm, 150 mm, 200 mm, 250 mm, and 300 mm diameters thereon and a second surface; anda rapid thermal process radiant heat source mounted outside said rapid thermal process reaction chamber so that radiant heat from said rapid thermal process radiant heat source directly heats said rotatable rapid thermal process susceptor and said single substrate,wherein said rapid thermal process radiant heat source raises the temperature of said single substrate to a substantially uniform processing temperature in a time period characteristic of a rapid thermal process reactor; andsaid rapid thermal process reactor can process substrates having diameters including 125 mm, 150 mm, 200 mm, 250 mm, and 300 mmdiameters so that said rapid thermal process reactor can be used to process substrates having a multiplicity of diameters.
