Design small, think big

Digital technologies have grown exponentially over the past decade, revolutionizing every industry on the planet and the way the world works and connects. At the basis of these technologies, semiconductors are the building blocks for producing data processors, memories, displays and photovoltaic cells that equip our computers, internet servers, smartphones, etc. Air Liquide's Electronics business line designs and supplies technological solutions based on very high purity gas and advanced materials, which help to produce semiconductors that are ever more performant and energy efficient, thus helping to meet the climate challenge.

Collaboration and inventiveness

Products manufactured by Electronics customers respond to increasingly challenging consumer demands for improved mobility, connectivity, computing power and energy consumption. These technological advances are made possible thanks to the innovative materials and gases used in semiconductors production.

In response, many of the advanced materials developed by Air Liquide have gone on to become industry standards, as a result of the Group’s early engagement with its customers. When new challenges arise, inventive answers are required. Air Liquide materials scientists and engineers turn these design challenges into solutions through innovation.

Our values

Working hand in hand with its customers every step of the way, Air Liquide invents the advanced solutions they need to accelerate innovation from the research laboratory to full-scale fabrication.

Our products and services offer

Carrier gases

Manufacturing electronic devices in a sterile environment is fundamental. Our ultra-pure gases (nitrogen, oxygen, argon, hydrogen, helium, CO2) guarantee the cleanliness and stability of our customers’ processes. Air Liquide supply these gases in bulk, via pipelines or via production with on-site dedicated plants.


Advanced materials

Delivered in canisters in small quantities, advanced materials are the basis for manufacturing ever more compact and powerful semiconductor chips. These highly complex processes are the key to improving the performance of electronic devices.


Specialty materials

Electronics specialty materials are the key process gases and chemicals to be used in the process for manufacturing of electronic components included anywhere from 20 to 250 steps.


Equipment & Installations

We also supply equipment for the distribution of gas and chemical products and install them at our customers’ facilities.


Customers rely on our expertise for the daily management of gases and chemical products on their sites, as well as to provide cutting-edge analytical services to continuously improve their production processes.
