Importance of Getters

STAYDRY products are developed to meet stringent industry requirements enabling hermetic package manufacturers security and peace of mind to meet industry reliability standards; including JEDEC, MIL STD 883 and NASA outgassing requirements.

Many hermetic packages and modules containing integrated microelectronic devices may out gas H2, H20, CO2 and other species over time. These outgassed species inside a hermetic package may degrade functionality of the device or specific components. Specific enabling technology products support stringent industry reliability standards; including JEDEC, MIL specification and Bellcore.

Outgassing in Hermetic Packages

Hydrogen outgassed from the hermetic package itself is a primary concern to long-term device reliability of GaAs devices which are susceptible to hydrogen poisoning. Hermetically sealed packages with semiconductor devices containing Pd or Pt gate metallization can have the hydrogen diffuse in the gate metallization and cause current or gain reduction of the device. Hydrogen trapped inside a hermetic package may degrade device functionality due to hydride formation with other metal substrates within the package. In some cases hydrogen can also create moisture in the presence of O2.

The Role of STAYDRY Getters in Hermetic Packages

STAYDRY getters capture, and in many cases, convert harmful species that are outgassed or present in a hermetic package. STAYDRY getters have been a proven solution to eliminate harmful contaminants for over 20 years in the aerospace, medical and telecom markets.

Depending upon your outgassed material concerns, manufacturing process and end-use device requirements, MacDermid Alpha has a STAYDRY getter product to maximize total cost of ownership while meeting life-time requirements.
