Abstract
An apparatus and method for a wafer level vacuum package uncooled microbolometer focal plane array (FPA) on a wafer level substrate with a thin film getter-reflector (G-R). The G-R removes gas from the vacuum package and is reflective in the frequency band of the FPA. Sensor pixels are supported about a quarter-wavelength above the G-R which is within the perimeter of the imaging array. The package is evacuated through a single aperture, and vacuum is maintained for the lifetime of the FPA. Imaging sensor size is reduced while maintaining resolution by reducing non-imaging area.
