As part of our commitment to the latest process technologies, we are currently driving the trend from wet to dry processing. Building on our expertise in thin-film silicon solar, our dry processing technologies are enabling smarter crystalline silicon manufacturing processes. Benefits include lower operating costs plus increased fab efficiency and performance. We also have the experience and expertise to optimise critical process steps such as etching/texturisation, doping, PSG removal, edge isolation, anti-reflective coating (ARC) deposition and various cleaning steps that are essential to cell performance.
We offer the full range of gas and chemical products to support all crystalline silicon cell manufacturing processes:
Ultra-pure bulk gases
Electronic special gases in cylinder and bulk supply
Special and wet process chemicals.
Materials for crystalline silicon cell manufacturing:
| Bulk Gases | Electronic Special Gases |
| Nitrogen | Silane |
| Hydrogen | Ammonia |
| Helium | Fluorine (on-site generation) |
| Oxygen | Sulphur hexafluoride |
| Argon | Chlorine |
| Carbon tetrafluoride | |
| Arsine and phosphine mixtures |
Exact requirements will vary depending on the process and manufacturing region.
Systems and service expertise
In addition, we offer a wide range of professional services to allow you to focus on your core business and keep operations up and running. These extend from turnkey design and installation services to end-to-end management of your gas systems and include:
Bulk gas storage and distribution systems
