Evaluation of Silicon Diaphragms for Hermetic Packaging of Microbolometer Arrays
(Chapter, 2020)Hermetic packaging is a critical requirement for microbolometers to maintain long-term reliability. A thinner diaphragm is desirable for vacuum packaging of microbolometers to obtain higher infrared light transmission. ... -
