Title The design and fabrication method of the electric heating micro OFF-switch for smart safe initiator
Abstract
In this paper， it was based on the study of MEMS safe initiator which LASS-CNRS laboratory developed to make a exploratory research of micro OFF-switch applied in smart logic control detonator initiation. The main contents include:
①The action principle of the micro OFF-switch was explained and the structural dimensions and material of the micro OFF-switch were designed.
②The MEMS technology craft involved in the fabrication of the OFF-switch was introduced. They includes: Graphic reversal lithography， magnetron sputtering technology， graphics PCM testing process， thermal oxidation process.
③The micro OFF-switch was fabricated. And the phenomenon during the fabrication was analysed. Then some advice of process optimization was proposed.
④The resistance of the fabricated micro OFF-switch resistive layer was measured and the fusing time was tested when it was under different voltage. Then the effects were tested when the micro OFF-switch worked. The applied voltage of the fabricated micro OFF-switch was about 16V.
