Patent ID: 8610033

Claim:
A rapid thermal process reactor comprising: a table top; a vessel including: a circular bottom wall including a chamber exhaust port; a cylindrical sidewall extending from the circular bottom wall and bounding a first part of a rapid thermal processing reaction chamber; a low profile dome having a height in a range of 0.25 inches to 1.5 inches, and an inner surface; and a flange, surrounding and abutting the low profile dome, having a bottom surface, wherein said inner surface is a part of a spherical surface, and the height is the distance from the bottom surface of the flange to the highest point on the inner surface, and wherein said inner surface of the low profile dome bounds a second part of the rapid thermal processing reaction chamber in the vessel; a rotatable susceptor assembly having a top surface, wherein the top surface is vertically movable and is positionable at a processing position in the rapid thermal processing reaction chamber; a gas ring, mounted about the cylindrical sidewall of said vessel, comprising an injector, the injector having a centerline, wherein said gas ring is mounted between the table top and the flange, and wherein the centerline of the injector is about tangent to the top surface of the rotatable susceptor assembly when the top surface is in the processing position; and a radiant heat source mounted outside said vessel and so radiant energy from said radiant heat source passes through said low profile dome, into said rapid thermal processing reaction chamber, to heat at least one substrate for rapid thermal processing.
