    摘要: A microelectromechanical system (MEMS) device includes a high density getter. The high density getter includes a silicon surface area formed by porosification or by the formation of trenches within a sealed cavity of the device. The silicon surface area includes a deposition of titanium or other gettering material to reduce the amount of gas present in the sealed chamber such that a low pressure chamber is formed. The high density getter is used in bolometers and gyroscopes but is not limited to those devices.

    摘要: A method for fabricating a semiconductor device includes patterning a sacrificial layer on a substrate to define a bolometer, with trenches being formed in the sacrificial layer to define anchors for the bolometer, the trenches extending through the sacrificial layer and exposing conductive elements at the bottom of the trenches. A thin titanium nitride layer is then deposited on the sacrificial layer and within the trenches. The titanium nitride layer is configured to form a structural support for the bolometer and to provide an electrical connection to the conductive elements on the substrate.
