Patent ID: 8310155

Claim:
An encapsulated sealed optoelectronic device comprising: an active device; a cap disposed over the active device to seal the active device and forming a cavity between the active device and the cap; a seal surrounding the active device and forming a sealed region; and a getter composition within the sealed region, wherein the getter composition comprises: a reactive material disposed in the encapsulated sealed optoelectronic device within the cavity, the reactive material comprising one or more of barium oxide, calcium oxide, calcium or barium; and an inert material disposed in the encapsulated sealed optoelectronic device within the cavity, the inert material being meltable in response to energy and formed of a different material from the seal, wherein the active device is at least partially covered by the getter composition, the inert material filling in cavities or indentations present on the surface of the active device and upon melting of the inert material inside of the sealed optoelectronic device the inert material changes shape; and wherein the cavity is arranged between the getter composition and the cap.
