By selectively adsorbing hydrogen, we solve problems related to hydrogen!
Using Pd or Pt as gate materials, the degradation caused by hydrogen in sealed packages containing gallium arsenide (GaAs) discrete FETs is a well-known phenomenon. The noble metal of the gate converts H2 molecules into H2 atoms, which then diffuse into the semiconductor material, leading to a reduction in current and device gain. Saes Group's hydrogen removal film, Rel-Hy, is a state-of-the-art getter solution. It is optimized to fully meet the very stringent requirements of microelectronic sealed packages suffering from hydrogen-related issues. Phenomena such as gate failures in gallium arsenide-based microelectronic devices caused by hydrogen, or degradation of insulation in ultra-adiabatic low-temperature systems, can be resolved by introducing getters that can selectively adsorb gases. Through Rel-Hy, Saes Getters provides getter solutions with excellent performance to the market, fully accommodating sealed packages such as those mentioned below.

basic information
Hydrogen gas can potentially cause degradation of particulate materials such as Pd and Pt when used in specific devices like GaAs devices. Hydrogen gas is well known for its ability to transfer heat efficiently, but it is also known to create dangerous situations, such as explosions, when large amounts of hydrogen are stored in sealed or semi-sealed containers. Additionally, hydrogen gas can be generated by the decomposition of moisture, which can lead to the expansion of the outer casing of semi-sealed electrochemical devices like Al capacitors and supercapacitors. In response to these technical needs, Saes has developed an efficient hydrogen getter. Saes' hydrogen getter does not require thermal activation and can withstand harsh environments and production processes. Furthermore, it features high adsorption performance per unit area.
