Embodiment Construction

[0045] The present invention provides an apparatus and method for processing small quantities or batches of one or more workpieces, such as semiconductor substrates or wafers, carried on a carrier, such as a cassette or vaporizer, so that Reduce processing cycle time and improve processing uniformity.

[0046] As used herein, the term "small batch" refers to a number of wafers that are less than several hundred wafers in a typical batch system, preferably in the range of 1 to about 53 semiconductor wafers, or where 1 to 50 semiconductor wafers are finished wafers, while the rest are non-finished wafers used for monitoring purposes and as blanker wafers.

[0047] Heat treatment refers to the process of heating the workpiece or wafer to a desired temperature in the range of about 350°C to 1300°C. Thermal processing of semiconductor wafers may include thermal treatment, annealing, diffusion or driving of dopant materials, deposition or growth of layers of material (eg, chemical ...

Abstract

An apparatus (100) and method are provided for thermally processing substrates (108) held in a carrier (106). The apparatus (100) includes a vessel (101) having a top (134), side (136) and bottom (138), and a heat source (110) with heating elements (112-1, 112-2, 112-3) proximal thereto. The vessel (101) is sized to enclose a volume substantially no larger than necessary to accommodate the carrier (106), and to provide an isothermal process zone (128) extending throughout. In one embodiment, the bottom wall (138) includes a movable pedestal (140) with a bottom heating element therein (112-1), and the pedestal can be lowered and raised to insert the carrier (106) into the vessel (101). The apparatus (100) can include a movable shield (146) that is inserted between the pedestal (140) and the carrier (106) to shield the substrates (108) from the heating element (112-1) and to maintain pedestal temperature. A magnetically coupled repositioning system (162) repositions the carrier (106) during processing of the substrates (108) without use of a movable feedthrough into the volume enclosed by the vessel (101), and without moving the bottom heating element (112-1) in the pedestal (140).
