We studied methods for enhancing handling stability of micro-tweezers in terms of tribology. Two items were examined experimentally. One is a method for increasing coefficient of friction on contact surface of the microtweezers. The other is whether making handling force large leads to increase of frictional force in the case of flexible structures like micro-tweezers. As for the coefficient of friction, we put focus on surface roughness of the contact surface processed by DEEP-RIE (ICP etching). We find that coefficient of friction become large by optimizing the surface roughness. As for relation between the frictional force and the handling force, we found that the both were approximately proportional. We think that the handling stability is improved by those methods.
