Products & solutions

Products — Our product portfolio includes UV-LED exposure systems for photolithography (UV-EXP), IR microscope for wafer inspection (IR-M), and vapor phase chemical etcher (VPE) for silicon-based devices. Since 2016, we also provide ion implantation services and machines for the surface treatment of materials.

Solutions — One of idonus' strengths lies in its ability to customize its products according to the needs of each client. The vertical integration of the company enables a fast prototyping, which results in short lead times for the customer.

Virtual tour

[21.02.2019] — Open house (PDF file, in French)

Customer feedback

Here is a collection of customer feedback about the HF vapor phase etcher.

EPFL is vey satisfied with the idonus HF Vapor etcher. The tool is very efficient and very complementary to other techniques like liquid HF etching followed by supercritical CO₂ drying. The HF vapor is able to release tiny structures on sacrificial SiO₂ layers with more success than any other known technique. The tool is safe and its price is very affordable.
— Dr. Philippe Flückiger, Director CMI - Center of MicroNanoTechnology , EPFL Lausanne, Switzerland.

I would like to congratulate you on the conception of this apparatus for its simplicity and safety. It is perfect for our applications as well as for the essential task of teaching the techniques of microfabrication.
— Philippe Vasseur, Laboratoire de Microfabrication de l'Ecole Polytechnique de Montréal, Canada.

The low spring constant of the structures made the release process difficult and a commercial vapour HF etcher made by idonus gave the best results.
