Abstract:
A component for forming a sealed package that includes a microelectronic device, comprising:a housing member; and sequentially deposited layers of metal layers attached to the housing member, to be positioned within the package when components of the package are assembled to form the package, said sequentially deposited layers of metal layers comprising a first layer of a first metal, closest to the housing member, adhering to the housing member and which traps hydrogen; a second layer further from the housing member than the first layer, said second layer being of a second metal for adsorbing larger amounts of hydrogen than trapped by said first layer, and an outermost layer of a third metal that converts hydrogen molecules to hydrogen atoms and also absorbs hydrogen, adjacent the second layer, the first, second and third metals being different metals; wherein said sequentially deposited layers further include at least one further layer of the first metal, between the first layer and the second layer, and at least one further layer of the second metal, between the first layer and the second layer.
