    Abstract: A pressure sensor (10) for use in a harsh environment including a substrate (14) and a sensor die (12) directly coupled to the substrate (14) by a bond frame (70) positioned between the substrate (14) and the sensor die (12). The sensor die (12) includes a generally flexible diaphragm (16) configured to flex when exposed to a sufficient differential pressure thereacross. The sensor (10) further includes a piezoelectric or piezoresistive sensing element (46) at least partially located on the diaphragm (16) such that the sensing element (46) provides an electrical signal upon flexure of the diaphragm (16). The sensor (10) also includes an connecting component (22) electrically coupled to the sensing element (46) at a connection location that is fluidly isolated from the diaphragm (16) by the bond frame (70). The bond frame (70) is made of materials and the connecting component (22) is electrically coupled to the sensing element (46) by the same materials of the bond frame (70).

    Abstract: A micro mirror structure including a plurality of individually movable mirrors. Each mirror has a generally concave shape from a top perspective at a temperature of about 20 degrees Celsius and has a generally convex shape from a top perspective at a temperature of about 85 degrees Celsius. In one embodiment, the radius of curvature may be greater than about 500 mm at a temperature of about 20 degrees Celsius and may be less than about -600 mm at a temperature of about 85 degrees Celsius at a thickness of about 10 microns. In another embodiment, the invention is a micro mirror structure including a plurality of individually movable mirrors arranged in an array. Each mirror includes a substrate, a diffusion barrier layer located above the substrate, and a reflective layer located above the diffusion barrier layer. The diffusion barrier layer generally limits the diffusion of the top reflective layer through the diffusion barrier layer.
