Apparatus, systems, and methods for processing workpieces are provided. An arc lamp can include a tube. The arc lamp can include one or more inlets configured to receive water to be circulated through the arc lamp during operation as a water wall, the water wall configured to cool the arc lamp. The arc lamp can include a plurality of electrodes configured to generate a plasma in a forming gas introduced into the arc lamp via the one or more inlets. The forming gas can be or can include a mixture of a hydrogen gas and an inert gas, the hydrogen gas in the mixture having a concentration less than 4% by volume. The hydrogen gas can be introduced into the arc lamp prior to generating the plasma. The arc lamp may be used for processing workpieces.

Arc lamp with forming gas for thermal processing systems

Systems and methods for reducing contamination of one or more arc lamps are provided. One example implementation is directed to a millisecond anneal system. The millisecond anneal system includes a processing chamber for thermally treating a substrate using a millisecond anneal process. The system further includes one or more arc lamps. Each of the one or more arc lamps is coupled to a water loop for circulating water through the arc lamp during operation of the arc lamp. The system includes a reagent injection source configured to introduce a reagent, such as nitrogen gas, into water circulating through the arc lamp during operation of the arc lamp.

A heating arrangement heats a first major surface of a workpiece with an illumination energy such that a first portion of the illumination energy is directly incident upon the first major surface of the workpiece and a second portion of the illumination energy is directed such that, at least initially, the second portion would miss the first major surface. A reflector, having a central opening, reflects at least some of the second portion of the illumination energy onto the peripheral edge region of the workpiece for preheating compensation. The reflector is configured for shadow-free exposure of a second, opposing major surface of the workpiece to a flash heating energy. A workpiece manipulation arrangement is described to provide for dynamic preheating movement to vary a heating profile across the workpiece and, thereafter, move the workpiece to a flash heating position. Automatic workpiece centering is featured by the manipulation arrangement.
