    Abstract: An apparatus and a method for controlling critical dimension (CD) of a circuit is provided. An apparatus includes a controller for receiving CD measurements at respective locations in a circuit pattern in an etched film on a first substrate and a single wafer chamber for forming a second film of the film material on a second substrate. The single wafer chamber is responsive to a signal from the controller to locally adjust a thickness of the second film based on the measured CD's. A method provides for etching a circuit pattern of a film on a first substrate, measuring CD's of the circuit pattern, adjusting a single wafer chamber to form a second film on a second semiconductor substrate based on the measured CD. The second film thickness is locally adjusted based on the measured CD's.

    Abstract: A method for forming a layer of material on a semiconductor wafer using a semiconductor furnace that includes a thermal reaction chamber having a heating system having a plurality of rotatable heaters for providing a heating zone with uniform temperature profile is provided. The method minimizes temperature variations within the thermal reaction chamber and promotes uniform thickness of the film deposited on the wafers.
