Abstract
Disclosed is an optical and/or microelectronics hermetic package which includes a member for absorbing hydrogen from the internal package ambient. The member includes a first layer which forms a hydride and, formed thereover, a second layer which forms solvated hydrogen upon exposure to molecular hydrogen in the package. The second layer acts as a one way valve for transporting hydrogen to the first layer which locks up the hydrogen.
Claims10
An hermetic package comprising:
- a housing for enclosing components;
- and
- a member within the housing and separate from the components, said member comprising a first layer of a material which forms a hydride when subjected to solvated hydrogen, and a second layer formed over the first layer, the second layer comprising a noble metal material which forms solvated hydrogen when subjected to molecular hydrogen and prevents formation of an oxide on the surface of the member.
