Techniques for the measurement of trace moisture in high-purity electronic specialty gases

The control of water vapor (moisture) contamination in process gases is critical to the successful manufacture of semiconductor devices. As specified moisture levels have become more stringent, there is a growing demand for more sensitive analytical methods. Instrumental methods currently being used or in development for measuring trace moisture at ppbv levels include Fourier transform infrared spectroscopy, tunable diode laser absorption spectroscopy, cavity ringdown spectroscopy, intracavity laser spectroscopy, electron impact ionization mass spectrometry, and atmospheric pressure ionization mass spectrometry. In addition, sensor-based technologies such as oscillating quartz crystal microbalances, and chilled mirror-, capacitor-, and electrolytic-based hygrometers operate in this regime. These approaches are presented and reviewed. As the success of each trace moisture method is dependent on the degree to which the different process gases interfere with the measurement process, important process gas applications of the techniques are highlighted. Advantages and disadvantages as well as future developments and trends are also presented.

Managers at Work: You Can Measure External Research Programs

External research projects at Air Products are delivering substantial benefits: * We are saving an average of two years of internal effort with each external project. * Most of our external projects save us hundreds of thousands of dollars of net research expenditures. * Our average external project provides novel technology using the unique skills and know-how of our partners and offers a potential revenue increase of tens of millions of dollars per year, or a profit increase of millions of dollars per year. How can we make such bold, sweeping statements? We have developed a simple tool to measure external research projects that provides us with a wealth of useful information. The tool consists of a table of rating scales that are used in conjunction with very brief, perhaps five-to ten-minute, interviews with the technical project champions to rate each project. We have evaluated 42 external projects to date with overall scores running from 8-34 out of a possible range of 2-34. We are confident that these projects will deliver the projected benefits, and we are particularly excited about reflecting the impact of that top-rated project in our bottom line! So far, we have only used this technique for our first annual snapshot review of our external projects, but the tool has provided such useful results that we are confident of its utility for other organizations. We expect to use it in the future to monitor changes in the projects as they go through the stages of development. Furthermore, we anticipate monitoring the follow-up commercial commitment and impact of these projects and look forward to replacing the estimates with actual project performance data. $5.5B Global Company Air Products and Chemicals, Inc. is a $5.5 billion global company producing industrial and specialty gases and chemicals. We perform about $130 million of RD our partners have found areas for research that have real value and uses along with access to additional funding. Our partners include industrial consortia, universities, government labs, and unique (often small) research and development companies. We were confident that we had gained competitive advantages through increased speed, improved probability of success, and reduced overall cost. However, we wanted to quantify these gains from our external technology projects, so we developed the table shown above, which provides a one-page-per-project rating tool.

Impurity Measurement in Specialty Gases Using an Atmospheric Pressure Ionization Mass Spectrometer with a Two-Compartment Ion Source

Using an atmospheric pressure ionization mass spectrometer (APIMS) with a two-compartment ion source, impurity in specialty gases (CH4, SiH4, GeH4) is measured due to a stable ionization reaction with a detection limit of approximately 0.1 to 1 parts per billion (ppb). The form in which the impurity exists in these gases has been clarified. In the case of SiH4, the main impurity is disiloxane (SiH3–O–SiH3). We have also established a method for obtaining the SiH3–O–SiH3 calibration curve standardized for a known concentration of SiH3–O–SiH3 generated from the reaction of SiH4 with H2O. In the case of CH4 and GeH4, the main impurity is moisture (H2O) and it is quantified from the plotted H2O calibration curve.

Trace Moisture Analysis in Specialty Gases

Even though we have been successful in reducing impurities, particularly moisture in bulk gases such as , Ar, and to below the 1 ppb level for semiconductor industry, the same performance has not been achieved in specialty gas delivery systems. This is due to the fact that these specialty gases are very active and corrosive, and they contain trace impurities including moisture. These gases react readily with gas delivery system surfaces and deteriorate the process equipment and performance. In order to reduce impurities in specialty gases, it is essential to improve our methods for measuring the impurity level in these gases, in particular, the residual moisture. The current techniques such as impedance‐type or crystal oscillation moisture detection systems are inadequate because these gases not only attack the system but also dissolve in adsorbed moisture on the sensor, causing the measuring conditions to change drastically, necessitating frequent cleaning and recalibration of the detector. To improve the reliability and the sensitivity of measuring the moisture level in specialty gases, we have developed a method to overcome these difficulties. The concept of the new method is quite simple. First, we pass a specialty gas of interest through tubing to allow the moisture to completely adsorb onto the tubing surface and reach the equilibrium between the gas and the solid surface. Then, we switch the gas and pass a carrier gas such as Ar through the tubing to desorb the moisture. The stripped moisture in the Ar carrier gas is then measured. We have demonstrated this method experimentally to measure the moisture level in and . We heated a piece of stainless steel tubing to 400–450°C and passed ultrahigh purity Ar containing 50 ppt moisture to completely strip off the adhered moisture from the inner surface. Next, the and gas with an unknown moisture level was introduced to the tubing system for a sufficient period of time for all the moisture to adsorb onto the surface and reach the gas and solid equilibrium. Then we switched the gas and passed an ultrahigh purity Ar carrier gas through the system to strip off the adsorbed moisture and subsequently the moisture in the carrier Ar was measured by atmospheric pressure ionization mass spectrometry by using the flow ratio of the Ar carrier gas and the gas. This new method was found to be useful to detect impurities in all specialty gases to ppb level.
