A structure is prepared by preparing a getter assembly by furnishing a single-piece getter base including a getter substrate and a getter-shield precursor, affixing a getter material to the getter substrate, and processing the getter-shield precursor to form a getter shield. The processing is preferably performed by folding at least a portion of the getter-shield precursor to overlie the getter material affixed to the getter substrate. There may be provided a vacuum housing and a device. The getter assembly and the device are inserted into the vacuum housing, and the vacuum housing is evacuated and sealed.
