    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.

    摘要: In one embodiment, a method of forming an out-of-plane electrode includes forming an oxide layer above an upper surface of a device layer, etching an etch stop perimeter defining trench extending through the oxide layer, forming a first cap layer portion on an upper surface of the oxide layer and within the etch stop perimeter defining trench, etching a first electrode perimeter defining trench extending through the first cap layer portion and stopping at the oxide layer, depositing a first material portion within the first electrode perimeter defining trench, depositing a second cap layer portion above the deposited first material portion, and vapor releasing a portion of the oxide layer with the etch stop portion providing a lateral etch stop.
