INNOVATIVE COMBO-LID SOLUTION TO ENTRAPPED GASES IN HERMETIC PACKAGING


Materion solves the problem of trapped gas within hermetic packaging with our unique Getter Combo-Lids™. This product combines our popular Combo-Lid™ (which is comprised of a ceramic or metal cover lid with an AuSn solder frame tack-welded to it) enhanced with a getter appropriate to the application. Getter is a material formulation that is applied for the purpose of absorbing gases within an enclosed cavity. In marrying the two, Getter Combo-Lids™ resolve the on-going problem of gas entrapped within a package that negatively impacts electronics.

Certain applications are especially dependent on high reliability, such as certain GaAs electronic devices, MEMS devices and other delicate sensors. To function successfully, they must be hermetically packaged within a sealed cavity completely free of hydrogen or other gases. Failure to eliminate all gases, particularly hydrogen in GaAs devices, can cause degradation in long-term functionality.

ADVANTAGES OF GETTER COMBO-LIDS™

Materion is an established leader in microelectronic packaging and thin film technology. Our innovative product offers many benefits for hermetic packaging, including:

  • Superior protection for all electronic devices
  • Multigas getters remove all gases (except noble gases) to create a vacuum in the sealed cavity
  • Hydrogen getters compatible with standard AuSn sealing ambient (like nitrogen)
  • Compatible with MEMS and GaAs devices
  • Longer-term vacuum stability
  • ISO 9001:2008, ITAR compliant available

GETTERING OPTIONS AVAILABLE DEPENDENT ON APPLICATION

Whether hermetic packaging requires gettering hydrogen alone, or needs to eliminate all gases (except for noble gases), we have a solution.

For gettering hydrogen:
Materion can weld a getter foil to the ceiling of the metal cover lid. This foil will getter hydrogen but is not affected by the ambient nitrogen used to reflow the Ausn solder during lid sealing.

For gettering all gases (except noble gases):
A thin film NanoGetter® is deposited onto the ceiling of a metal or ceramic cover lid. The getter will be activated during the reflow of AunSn solder to seal the lid. A Combo-Lid™ enhanced with NanoGetter® should be sealed in an ambient of vacuum or argon so it can preserve the vacuum in the sealed cavity.

LEADING THE INDUSTRY FOR A WIDE RANGE OF APPLICATIONS

Our innovative Getter Combo-Lids™ offer hermetic packaging solutions for multiple applications. They increase reliability and performance in products such as: GaAs electronic devices, MEMS devices, chemical sensors, IR detectors, accelerometers and gyroscopes, bolometers, resonators, pressure & flow sensors and more.
