Patent ID: 8137462

Claim:
A chemical reactant source vessel in combination with a gas delivery system for a vapor phase reactor for vapor processing of substrates, comprising: a vessel body defining an internal chamber adapted to contain a solid or liquid chemical reactant, wherein the vessel body includes an inlet and an outlet; an inlet passage within the vessel body, the inlet passage extending from outside the vessel body to the vessel chamber; an inlet valve attached directly to a substantially flat surface of the vessel body and configured to regulate flow through the inlet passage; an outlet passage within the vessel body, the outlet passage extending from the vessel chamber to outside the vessel body; an outlet valve attached directly to the substantially flat surface of the vessel body and configured to regulate flow through the outlet passage; a vapor phase reaction chamber for processing substrates; a plurality of gas panel valves collectively operative to convey a carrier gas through the vessel and into the reaction chamber, at least one of the gas panel valves being fluidly interposed between the outlet valve and the reaction chamber; and a heater plate interposed between the gas panel valves and the flat surface of the vessel body, the heater plate configured to heat up the gas panel valves and the vessel; wherein all of the gas panel valves are positioned within about 10.0 cm from the flat surface of the vessel body.
