Getter housing for electronic packages

摘要

A package for an electrical or optoelectronic device comprising a hermetically sealed container having a getter for organic impurities and water. The getter, which is composed of a porous material, is relatively fragile and is subject to particulate shedding during use of the device. To prevent failure of components within the container, the getter is contained within a housing that has sufficiently small apertures or interstices that it is permeable to water vapor and organic impurities but it retains any particles separate from the getter.
