    Abstract: A vertically integrated micro-bolometer includes an integrated circuit chip, an infrared sensing film, and a metal bonding layer. The integrated circuit chip includes a silicon substrate, a circuit element, and a dielectric layer disposed on the silicon substrate. The infrared sensing film includes a top absorbing layer, a sensing layer, and a bottom absorbing layer. The sensing layer is disposed between the top absorbing layer and the bottom absorbing layer. Materials of the top absorbing layer, the sensing layer, and the bottom absorbing layer are materials compatible with a semiconductor manufacturing process. The metal bonding layer connects the dielectric layer on the silicon substrate in the integrated circuit chip and the bottom absorbing layer of the infrared sensing film to form a vertically integrated micro-bolometer. In one embodiment, the infrared sensing film is divided into a central sensing film, a surrounding sensing film, and a plurality of connecting portions by a plurality of slots. The surrounding sensing film surrounds the central sensing film. Each of the connecting portions connects the surrounding sensing film and the central sensing film. A central distance from the bottom absorbing layer of the central sensing film to the silicon substrate is substantially equal to a surrounding distance from the bottom absorbing layer of the surrounding sensing film to the silicon substrate.

    Abstract: The disclosure relates to a microelectromechanical apparatus including a substrate, a stationary electrode, a movable electrode, and a heater. The substrate includes an upper surface, an inner bottom surface, and an inner side surface. The inner side surface surrounds and connects with the inner bottom surface. The inner side surface and the inner bottom surface define a recess. The stationary electrode is disposed on the inner bottom surface. The movable electrode covers the recess. The movable electrode, the inner bottom surface, and the inner side surface define a hermetic chamber. The heater is disposed on the movable electrode and located above the hermetic chamber.

    Abstract: A calibration system for calibrating pressure sensor comprises communication pipe, base, inlet valve, outlet valve, pump, inlet pipe, heater and reference pressure sensor. The communication pipe has first and second openings. The base comprises chamber body and outlet being disposed at the chamber body. The inlet valve is disposed at the first opening. The chamber body is connected to the second opening so as to define a space between the inlet valve and the outlet valve. The heater is to heat a fluid in the space. The reference pressure sensor is configured to measure a pressure of the fluid. The at least one target pressure sensor is detachably mounted on the chamber body via the base so as to measure the pressure of the fluid in the space.
