Advanced Getter Solutions for Gas Contaminants Absorption in Optoelectronic Devices

Abstract

Sealed optoelectronic devices may experience performance issues, or failures, due to outgassing and release of gas species like H2O, H2, and VOCs during the operating lifetime. Hermetic packaging is the standard solution for sealing opto-electronic devices in order to protect them from external atmosphere or harsh environments, ensuring higher reliability and longer life. Unfortunately, hermeticity is not effective to prevent the release of gases from materials that are inside the sealed device. Accumulation of H2, H2O or VOCs could significantly affect the devices, leading to poor performances and drift over the lifetime. An effective way to fix this issue is to integrate getter materials. The engineered absorbing materials developed by SAES can be integrated into the packages to selectively absorb gases and preserve the device performances.
