英文摘要: As the improving of the integration and complexity of the NEMS semiconductor devices, the flexible operation technology based on SEM has become one of the key technologies of semiconductor manufacturing. Under the background, this research put forward a kind of inertia stick-slip driven trans-scale precision motion technology based on SEM, in view of high integration and high vacuum degree environment. Starting from research inertia stick-slip driving mechanism, put forward the kinematic model of the high integration of inertia stick-slip driven trans-scale precision movement in different frequency range. From the study of the movement contact friction interface conversion mechanism in high vacuum environment, the different contact surface texture friction mechanics model is set up. Combined with the electromechanical coupling model of the driving source, the dynamics research of the inertia stick-slip driven trans-scale precision motion for SEM was proceed. Eventually, a platform with high precision and high integration is suitable for high vacuum environment for precision movement based on SEM is built, at the same time for movement more than 10 mm, the total size less than 20 mm×20 mm×15 mm. This technology provides new ideas and methods for trans-scale precision motion based on SEM and to provide an effective movement and positioning tool for nanomanipulation.
