An improved hydrogen generation system and method for using the same are provided. The system includes an HDS unit configured to remove sulfur, a first and second pre-reformers configured to pre-reform a process gas and fuel gas, respectively, a first and second heat exchangers configured to dry and heat the pre-reformed fuel gas, respectively, and a reformer configured to produce a syngas and flue gas. The method includes using a process stream selected from the group consisting of air, PSA off-gas, hydrocarbon gas, and combinations thereof to dry the fuel gas and using a process stream selected from the group consisting of the flue gas, the syngas, and combinations thereof to heat the dry fuel gas. The second pre-reformer is a low-pressure pre-reformer, so that the heat contents of the fuel gas is increased through converting heavy hydrocarbons in the fuel gas to CO and Hby the second pre-reformer.

A chemical storage device and a method for monitoring chemical usage are described herein. The device and disclosed method utilize a chemical storage canister and a load cell integrated into one transportable unit. The load cell is capable of compensating for the added weight of attached dispensing devices used in the semiconductor industry. Additionally, the load cell continuously displays the weight of the chemicals as they are withdrawn from the chemical storage device. These functionalities are included in the control logic of the load cell which is incorporated into the load cell itself.

Provided is a novel chamber effluent monitoring system. The system comprises a chamber having an exhaust line connected thereto. The exhaust line includes a sample region, wherein substantially all of a chamber effluent also passes through the sample region. The system further comprises an absorption spectroscopy measurement system for detecting a gas phase molecular species. The measurement system comprises a light source and a main detector in optical communication with the sample region through one or more light transmissive window. The light source directs a light beam into the sample region through one of the one or more light transmissive window. The light beam passes through the sample region and exits the sample region through one of the one or more light transmissive window. The main detector responds to the light beam exiting the sample region. The system allows for in situ measurement of molecular gas impurities in a chamber effluent, and in particular, in the effluent from a semiconductor processing chamber. Particular applicability is found in semiconductor manufacturing process control and hazardous gas leak detection.

Provided is a novel system and method for delivery of gas from a liquefied state. The system includes (a) a delivery vessel holding a bulk quantity of liquefied gas therein; (b) a heat exchanger disposed on the delivery vessel to provide or remove energy from the liquefied gas only; and (c) a pressure controller for monitoring and adjusting the energy delivered to the vessel. The system and method allow for controlled delivery of liquefied gas from a delivery vessel at a predetermined flow rate. Particular applicability is found in the delivery of gases to semiconductor process tools.

A circuit board is wave soldered as it is carried by a conveyor through a solder wave established in a solder reservoir. Disposed on both sides of the solder wave are gas plenums which discharge shield gas. Each gas plenum includes a top wall, a side wall, and a bottom wall. The side wall is spaced horizontally from the wave, and the bottom wall is submerged within the solder. The side and (optionally) top walls include orifices for directing shield gas (i) at high velocity toward the solder wave to protect the solder wave with an atmosphere of shield gas, and (ii) upwardly toward an underside of the circuit board to strip entrained air therefrom. Instead of being submerged within the solder, the bottom wall could be spaced above the solder and provided with orifices to emit shield gas downwardly between the plenum and solder reservoir to create an inert atmosphere above the solder. Dividers disposed within the plenum form sub-chambers communicating with orifices in respective walls of the plenum so that different gas velocities can be entitled from the orifices. The gas plenums can be rotatably adjustable and further adjustable either vertically or horizontally.
