About SAL

Surf's Up

The project “Surf’s Up” is committed to the development of a new generation of radio-frequency filters and resonators based on a new technology of layer transfer and epitaxial nitride films fabricated by magnetron sputtering.

Project goals

This project aims to:

  • Innovate the current technology of RF filters based on bulk acoustic waves in piezoelectric materials (e.g. AlScN)
  • Investigate the relations between all the components of the film stack such as electrode layers and acoustic mirror
  • Develop epitaxial Al0.7Sc0.3N on commercially available substrates in an industrial scale via magnetron sputtering
  • Develop a new microfabrication process including the layer transfer of an epitaxial Al0.7Sc0.3N thin film for high-quality resonator structures
  • Demonstrate the performance of Al0.7Sc0.3N and interdigitated transducer (IDT) structures for opto-acoustic applications

ENLIGHTEN

The ENLIGHTEN project strengthens Europe's independent access to space by developing a sustainable liquid hydrogen engine demonstrator. For this, SAL is developing a cost-efficient fiber optic multiplex laser ignition system that supplies multiple ignition points from a single laser source and will be tested under demanding engine conditions up to TRL 5….

Mag-TF

The Mag-TF initiative aims to establish a pilot facility for the development, manufacturing, and characterization of advanced magnetic thin films for spintronic and MEMS applications. This includes the acquisition of specialized equipment for thin film deposition as well as for wafer-level magnetic device characterization. The Mag-TF infrastructure will be integrated into the existing SAL microfabrication facility.

NOVETROL

Within the NOVETROL project, a novel, fast, passive, and self-regulating current limiter for DC networks is being investigated. This device is based on the extraordinary magnetoresistance effect occurring in semiconductors with very high charge carrier mobility. The component functions similarly to a thermistor: instead of increasing its resistance with rising temperature, the resistance increases in response to the magnetic field generated by the fault current that the system is intended to limit….
