GETTER HAVING TWO ACTIVATION TEMPERATURES AND STRUCTURE COMPRISING THE GETTER

摘要

PROBLEM TO BE SOLVED: To provide a getter which is easy to implement, is made very compact and enables the pressure in the closed cavity of a structure to be controlled.

SOLUTION: The structure comprises the closed cavity under a controlled atmosphere, in which a monoblock getter with a first getter layer 9a is arranged. The first getter layer 9a presents at least first 9a1and second 9a2getter areas which have different activation temperatures. The second getter area 9a2is formed on an adjustment sub-layer 10 of the getter material activation temperature.
