SILSEF is a performing SME specialised in nano-patterned functional surfaces, in particular for optics (anti-reflection, diffraction/decoration) and wetting engineering. It develops innovative and patented technologies to create high performance surfaces combining bulk (chemical) properties with those generated by nano-imprint (physical) patterning on semiconductors, metals, glass and polymers. SILSEF is involved in funded projects (ANR, DGA/Astrid Maturation, Eurostars) and joint- development with customers. It shares a 2.000m2 semiconductor plant with Silicon wafer manufacturer Sil’Tronix near Annecy with cleanrooms and various caharcterisation tools. Wetting control is a strategic area under development through academic partnerships (NILAB open Innovation platform). In particular, SiLSEF currently has a PhD student focused on hydrophobic coatings in collaboration with LMI lab in Lyon.
