Facilitating innovation of the electronics industries

Long-term provider of innovative solutions for the markets of semiconductors, photovoltaics and flat panel displays, we contribute to the innovation of the world’s most advanced companies in the electronic industry. As a world reference in the design, manufacturing and delivery of molecules, we conceive for our clients the infinitely small and enable them to think amazingly big.


In the world of the semiconductor industry, size always matters. Integral to everything from processors found inside smartphones or computers to memory chips and image sensors, the use of semiconductor chips or integrated-circuits is now spreading outside the digital world. With every new application and end-user expectations for more performances come ever-greater challenges to produce smaller and more cost-efficient semiconductor chips. Manufacturers can rely on Air Liquide to allow them to develop their technical road map.

Air Liquide accompanies semiconductor manufacturers, delivering the ultra-high purity carrier gases needed to keep their manufacturing processes clean and stable over time. We also supply the specialty and advanced electronics materials (also called precursor molecules) to produce the semiconductor chips, and provide the equipment and services for the safe and optimum analysing handling and distribution of our products.

Our ALOHA™ and Voltaix™ product lines are designed for the most sensitive stage of the microchip manufacturing process, with the nano-scale transistors industrialization. For each new generation of semiconductors, Air Liquide invents and produces electronics advanced materials with specific chemical, thermal, physical and high-purity properties for the semiconductor industry.

We are also partnering with leading customers and technology centers of excellence to conceive new molecules like our enScribe™ family of products for new etching applications and material that respond to emerging semiconductor industry technology challenges.

We provide core capabilities that cover all major stages of semiconductor production, including:

  • Carrier Gases (generated on-site or delivered in bulk) including nitrogen, oxygen, hydrogen, helium and argon
  • Electronics advanced materials for chemical vapor deposition (CVD) and atomic layer deposition (ALD)
  • Electronics specialty materials such as silane or halogen gases that can be supplied in large containers
  • Analytical services to improve our customers’ process and production yields
  • Total Gas and chemical management to ensure the safe, reliable, and cost-effective management of the gases and chemicals needed on a daily basis in the production of electronics materials.
  • Equipment & Installations to offer the right equipment, uncompromised safety, best-in-class reliability, and greater all-round control.

Flat panel displays

The need to continuously improve the user experience creates demand for a new generation of displays that are cheaper, thinner, lighter, more energy-efficient, flexible and higher in resolution. Already, advances in display technology have enabled the creation of curved television sets or flexible screens that offer very deep contrast and smart-phones that run twice as long.

100% of flat panel display production capacity is shared between Korea, Japan, Taiwan, China and Singapore. Screens are produced in semiconductor-like fabrication plants, also called fabs, which require about 20 electronics specialty materials (also called precursor molecules) in very large volumes.

Air Liquide supports the needs of these manufacturers for producing next-generation displays and continues to invest in large high purity nitrogen on-site gas production units to accompany their rapid growth over the long term.


As the world turns to renewables, solar photovoltaic system installation has been steadily increasing. The global solar photovoltaic end-market has maintained double-digit growth in certain geographies, sometimes with various financial supports from governments. After a long period of evolution, solar photovoltaic manufacturing has split into two main fields: crystalline silicon (c-Si) with 95% of the global production, and thin film (TF) solar.

To provide more affordable solar energy, the entire photovoltaic supply chain is in need of new materials and technologies that drive panel performance up and costs down.

Since investing in monosilane production in Japan for the semiconductor and photovoltaic industries in 1987, we have been committed to accompanying the industry towards sustainability, profitability and growth. Our recent investment in a crystalline silicon solar cells demonstration and pilot production line, extensive R&D and academic collaborations, and innovative product offerings, are just some examples of our work in the field.

As the worldwide leader in gas supply to the photovoltaic industry, Air Liquide is able to respond promptly with the right solution for technology problems and, most important of all, create value for its customers.
