A vaporization chamber for a substrate processing system includes a main body, a cover member and a transition member. The main body is made of aluminum and defines a first inner surface, which defines, at least in part, a cavity. The cover member is also made of aluminum. The cover member defines a second inner surface, which also defines, at least in part, the cavity. The cover member includes a carrier gas cover inlet, a liquid source cover inlet, a source cover outlet which extends from a first outer surface through the cover member to the second inner surface. The transition member is made of stainless steel and has a transition outer surface and a transition inner surface. The transition inner surface is aluminum cladded. The cover member includes a carrier gas cover inlet, a liquid source cover inlet, a source cover outlet which extend from a first outer surface through the cover member to second inner surface. The transition inner surface and the cover outer surface are welded together.

One or more of three different measures are taken to preheat a wafer before it is loaded into direct contact with a wafer holder, in order to provide optimal throughput while reducing the risk of thermal shock to the wafer. The first measure is to move the wafer holder to a raised position prior to inserting the wafer into the reaction chamber and holding the wafer above the wafer holder. The second measure is to provide an increased flow rate of a heat-conductive gas (such as Hpurge gas) through the chamber prior to inserting the wafer therein. The third measure is to provide a power bias to radiative heat elements (e.g., heat lamps) above the reaction chamber.

A substrate holder for processing a semiconductor substrate that minimizes substrate non-uniformities as well as backside damage. The substrate holder includes one or more support elements, such as a plurality of veins configured in an annular ring to support an outer edge of a substrate. The veins are configured to support a substrate of a particular size in a support plane defined by the top surfaces of the veins. The substrate holder also has one or more annular grooves formed in the top surface of the holder. In a preferred embodiment, the substrate holder also has a raised annular ring positioned radially inward of the grooves and the support elements. The top surface of the raised annular ring is no higher that the top surfaces of the veins.
