Cavity-enhanced direct frequency comb spectroscopy (CE-DFCS) has demonstrated powerful potential for trace-gas detection based on its unique combination of high bandwidth, rapid data acquisition, high sensitivity, and high resolution, which is unavailable with conventional systems.However, previous demonstrations were limited to proof-of-principle experiments or studies of fundamental laboratory science.Here, the development of CE-DFCS towards an industrial application-measuring impurities in arsine, an important process gas used in III-V semiconductor compound manufacturing is presented.A strongly absorbing background gas with an extremely complex, congested, and broadband spectrum renders trace detection exceptionally difficult, but the capabilities of CE-DFCS overcome this challenge and make it possible to identify and quantify multiple spectral lines associated with water impurities.Further, frequency combs allow easy access to new spectral regions via efficient nonlinear optical processes.Detection of multiple potential impurities across 1.75-1.95 μm (5710-5130 cm^-1) is demonstrated, with a single-channel detection sensitivity (simultaneously over 2000 channels) of ≈4 × 10^-8 cm^-1 Hz^-1/² in nitrogen and, specifically, an absorption sensitivity of ∼4 × 10^-7 cm^-1 Hz^-1/² for trace water doped in arsine.

Cylinder Materials of Construction for Ultra-High Purity HBr in Advanced Semiconductor Etch Processes

作者: Mark Raynor ; Robert Torres ; P. Jha ; Jianlong Yao ; E. W. Olsen ; Carrie Wyse ; Adam J. Seymour

Anhydrous HBr used in etch processing for the semiconductor industry requires strict impurity control. However, the gas cylinder material of construction plays a critical role in controlling and maintaining purity levels of the delivered HBr process gas and must be carefully selected. In this work Ni-lined AISI 4130 Cr-Mo steel cylinders are compared against the gas industry standard AISI 4130 Cr-Mo steel cylinders with regard to (a) surface roughness/area and oxide layer thickness after exposure to HBr and (b) the concentration of moisture in delivered HBr gas. Over the period of a year, the surface roughness increase of the polished Cr-Mo steel package doubles that of the Ni-lined package and the penetration of the oxide layer into the metal for the Cr-Mo steel is over 10 times that for the Ni surface. Finally the more inert surface of the Ni lining is shown to lower the moisture concentration in the HBr gas by ~4 times. These findings demonstrate that Ni-lined AISI 4130 Cr-Mo steel provides a superior package for Ultra High Purity HBr storage and delivery.

Article

作者: Bertness, Kris A. ; Funke, Hans H. ; Chen, Yu ; Raynor, Mark W.

The presence of trace water vapor in process gases such as phosphine, used for compound semiconductor epitaxial growth, can negatively affect the optical and electrical properties of the final device. Therefore, sensitive H2O measurement techniques are required to monitor precursor purity and detect unacceptable contamination levels. A commercial cavity ring-down spectrometer that monitors an H2O absorption line at a wavelength of 1392.53 nm was investigated for service in high purity PH3. Spectral parameters such as the line shape of water vapor in the presence of PH3 as well as background features due to PH3 were measured at different pressures and incorporated into the data analysis software for accurate moisture readings. Test concentrations generated with a diffusion vial-based H2O source and dilution manifold were used to verify instrument accuracy, sensitivity, linearity, and response time. H2O readings at 13.2 kPa corresponded well to added concentrations (slope = 0.990 ± 0.01) and were linear in the tested range (0–52.7 nmol mol−1). The analyzer was sensitive to changes in H2O concentration of 1.3 nmol mol−1 based on 3σ of the calibration curve intercept for a weighted linear fit. Local PH3 absorption features that could not be distinguished from the H2O line were present in the purified PH3 spectra and resulted in an additional systematic uncertainty of 9.0 nmol mol−1. Equilibration to changing H2O levels at a flow rate of 80 std cm3 min−1 PH3 occurred in 10–30 minutes. The results indicate that cavity ring-down spectroscopy (CRDS) at 1392.53 nm may be useful for applications such as on-line monitoring (and dry-down) of phosphine gas delivery lines or the quality control of cylinder sources.

Outlook on the Helium Global Market to 2030 - Identify Key Drivers and Challenges

Dublin, July 02, 2021 (GLOBE NEWSWIRE) -- The "Global Helium Market Analysis: Plant Capacity, Production, Operating Efficiency, Technology, Demand & Supply, End-User Industries, Distribution Channel, Regional Demand, 2015-2030" report has been added to ResearchAndMarkets.com's offering. Global helium demand is projected to grow at a healthy CAGR of 4.65%. Helium is a chemically inert gas which liquifies at low temperatures. It is commercially available in two forms namely gas and liquid. It has many properties including non-reactive, non-corrosive, and non-flammable properties. Due to these properties, helium finds application in many areas including breathing mixes, cryogenics, leak detection, welding, pressurizing and purging, controlled atmosphere, and others. It has many end use industries such as aerospace, electronics and semiconductors, nuclear power, healthcare, welding, metal fabrication, others. Growing demand from healthcare industry where it is used in magnetic resonance imaging (MRI) for magnet cooling and semiconductor and electronics industry where it is used in the manufacturing of LED screens is expected to drive the demand of helium during the forecast period. Moreover, stringent government regulations regarding usage of helium and expensive extraction process might hinder the demand growth during the forecast period. Additionally, the growing demand for ultra-low temperature freezers is expected to push the demand further during the forecast period.In 2020, the spread of COVID-19 in major global economies caused nationwide lockdowns which had an impact on a number of industries. Medical gases were among the most affected industries during the pandemic. This had an impact on the demand of helium for the first half of 2020. The demand for helium grew during the coronavirus pandemic. However, the demand of semiconductors and electronics fell during the pandemic. This negatively affected the demand of helium.Region wise, Asia pacific region holds the major share of global demand for helium due to increasing demand of healthcare and semiconductors and electronics. Moreover, increasing population and per capita income in emerging economies like India and China coupled with growing number of industries using helium is another factor influencing demand growth in the Asia Pacific region. Objective of the Study: Major players for helium globally include Air Liquide, Exxon Mobil Corporation, Gulf Cryo, Linde Plc, Messer Group GmbH, PGNIG SA, Renergen, Air Products and Chemicals, Inc., Gazprom, Iwatani Corporation, Matheson Tri-Gas Inc., NexAir LLC, Qatargas Operating Company Limited, Weil Group.To extract data for global helium market, primary research surveys were conducted with helium manufacturers, suppliers, distributors, wholesalers and end users. While interviewing, the respondents were also inquired about their competitors. Through this technique, the publisher was able to include manufacturers that could not be identified due to the limitations of secondary research. Moreover, the publisher analyzed various end user segments and projected a positive outlook for Global helium market over the coming years.The publisher calculated helium demand globally by analyzing the historical data and demand forecast which was carried out considering imported helium, prices, materials used for production of helium . The publisher sourced these values from industry experts and company representatives and externally validated through analyzing historical sales data of respective manufacturers to arrive at the overall market size. Various secondary sources such as company websites, association reports, annual reports, etc., were also studied.Key Target Audience: The study is useful in providing answers to several critical questions that are important for industry stakeholders such as helium manufacturers, customers and policy makers. The study would also help them to target the growing segments over the coming years (next two to five years), thereby aiding the stakeholders in taking investment decisions and facilitating their expansion.Key Topics Covered: 1.
