Alfa Chemistry has the experience and equipment necessary to both prototype and mass produce sub-micron surfaces at industry leading prices. Our expert staff uses 30 years of manufacturing experience and the most advanced equipment to provide various surface structuring services.
As a full-service organization, we provide all aspects from concept to production, including design consulting. Various services can help you complete the entire project. In addition to our standard test mode, we also provide custom services based on end user designs.
Our surface structuring technology can be divided into nano-structuring and micro-structuring. In nanostructures, with the help of multiple technologies, structures with lateral dimensions in the nanometer range (<1 µm) can be created in various layers (such as Si, SiO2 or Al). Both technologies can use various technologies and standard equipment.
ENAS uses nanoimprint lithography (NIL) to create nanostructures and produces high-resolution wafers through electron beam exposure. The positive imprint of the master can be printed into the nano-thick photoresist layer by copying, and the photoresist layer is cured by ultraviolet rays. Finally, these nanostructures can be transferred to various materials by dry etching.
In microstructuring, a polymer or polymer layer can be constructed in the micrometer range by photolithography and imprinting methods. These structures can be transferred to various materials by wet chemistry and dry etching.
