Sacrificial Microchannel Sealing by Glass-Frit Reflow for Micromachined Alkali Gas-Filled Cell


A novel sealing technique using sacrificial microchannels was proposed for atmosphere control in a micromachined alkali gas-filled cell used in atomic magnetometer. The microchannels act as feedthrough connecting a cell to outside atmosphere during evacuation and gas-filling steps, and eventually they are sealed by glass-frit reflow. The purposes of this research are optimizing parameters by experiments and simulation using plastic molding CAE software and fabricating atomic magnetometer.
