EMBEDDED STRUCTURES FOR HIGH GLASS STRENGTH AND ROBUST PACKAGING
A sensor device is constructed to maintain a high glass strength to avoid the glass failure at low burst pressure, resulting from the sawing defects located in the critical high stress area of the glass pedestal as one of the materials used for construction of the sensor. This is achieved by forming polished recess structures in the critical high stress areas of the sawing street area. The sensor device is also constructed to have a robust bonding with the die attach material by creating a plurality of micro-posts on the mounting surface of the glass pedestal.
INFRARED SENSOR DESIGN USING AN EPOXY FILM AS AN INFRARED ABSORPTION LAYER
A MEMS IR sensor, with a cavity in a substrate underlapping an overlying layer and a temperature sensing component disposed in the overlying layer over the cavity, may be formed by forming an IR-absorbing sealing layer on the overlying layer so as to cover access holes to the cavity. The sealing layer is may include a photosensitive material, and the sealing layer may be patterned using a photolithographic process to form an IR-absorbing seal. Alternately, the sealing layer may be patterned using a mask and etch process to form the IR-absorbing seal.

Systems and methods for nuclear event circumvention in an inertial device
Systems and methods with the ability to raise the set point temperature immediately after a temperature increase due to radiation exposure, thereby reducing T-dot (rate of change in temperature) errors when trying to cool the inertial system back to its original set point temperature. An example system includes an inertial instrument, a sensor that senses if an increased temperature event has been experienced by the inertial instrument, and a controller device that will increase the set point temperature of the inertial instrument based on the determined increase in temperature. The controller device will also maintain the inertial instrument at a temperature associated with at least one of the sensed increased temperature event or the increased set point temperature.
