Containers for providing vapor phase reactant from liquid sources include bubbler designs and designs in which carrier gas flows over the liquid surface. Among the bubbler arrangements, a bypass conductance is provided to release excess pressure from the gas volume inside the container, or an enlarged bubbler tube is provided with a volume sufficient to accommodate all possible liquid backflow without having the liquid exit the container. Among the overflow designs, flow dividers provide a tortuous path for the gas to increase the time exposure of carrier gas packets to the evaporating liquid surface. The flow dividers can be microporous to encourage capillary action, thereby increasing the evaporating surface. The tortuous gas flow path can be separated from the liquid phase by a breathable semi-porous membrane that permits vapor phase reactant to pass through but prohibits liquid from passing in the other direction.

Provided is an in-situ precleaning method for use in conjunction with epitaxial processes that utilizes temperatures at or below those typically utilized during the subsequent epitaxial deposition under pressure and ambient conditions suitable for inducing decomposition of semiconductor oxides, such as native oxides, from exposed semiconductor surfaces. The reduced temperature and the resulting quality of the cleaned semiconductor surfaces will tend to reduce the likelihood of temperature related issues such as unwanted diffusion, autodoping, slip, and other crystalline stress problems while simultaneously reducing the overall process time. The combination of pressure, ambient gas composition and temperature maintained within the reaction chamber are sufficient to decompose semiconductor oxides present on the substrate surface. For example, the reaction chamber may be operated so that the concentration of evolved oxygen within the reaction chamber is less than about 50%, or even less than 10%, of the equilibrium vapor pressure under the cleaning conditions.

The presence of trace molecules in air is often determined using a well-known device called an ion mobility spectrometer. Such devices are commonly utilized in the fields of explosives detection, identification of narcotics, and in applications characterized by the presence of very low airborne concentrations of organic molecules of special interest. The sensitivity of such instruments is dependent on the method of gas sampling utilized. The vortex sampling nozzle consists of an intake gas flow and a separate coaxial heated, emitted gas flow that is deflected to move with a circular motion. A heated vortex sampling nozzle can greatly improve the sampling efficiency for low volatility target molecules, particularly when the sampling needs to be performed at a distance from the air intake and the vapor pressure of the target molecules is very low. Additionally, the vortex air may contain one or more additional substances that promote vaporization, combine with the target molecule, or provide a known marker in the ion mobility time-of-flight spectrum.

A continuous ink jet printer has a line (69a) for venting at least some of the air that has been sucked along the gutter line (17), and a line (69b) for recirculating back to the printhead (25) at least some of the air that has been sucked down the gutter line (17). Preferably the relative proportions of vented air and recirculated air can be varied, so as to reduce solvent loss during normal operation but allow increased solvent loss if the ink is over-dilute. Preferably the air recirculated to the printhead is connected directly into the flow path from the gutter orifice to the source of gutter suction, without opening into the space containing the ink jet. This reduces the tendency of solvent in the recirculated air condense on the printhead electrodes.
