초록

In this paper, a new structure of probe unit is designed and fabricated with PDMS, which is well-known elastic material, as a buffer layer for increasing overdrive force and mechanical strength. In general, PDMS is widely used as actuation material due to its elasticity and compatibility of fabrication process. In this work, PDMS layer is chosen for mechanical elasticity of the proposed probe unit. We achieved the high overdrive force by placing PDMS buffer layer under the silicon based cantilever due to its elasticity. Moreover, the relation between prove length and overdrive force was measured by experiment in this work. Therefore, the various specifications of the micro prove unit can be designed by using the results of this work.
