本論文研製一奈米級長行程精密定位平台,並整合精密控制、精密量測、結構設計與加工組裝等四項主體,其特色是結合X-Y雙軸長行程導螺桿平台、三自由度壓電微動平台、三自由度量測系統與雙軸長行程奈米級精密平台控制系統。藉由X-Y雙軸長行程導螺桿平台進行微米級長行程定位後,再由三自由度壓電微動平台進行奈米級定位,最後經由三自由度量測系統,將量測數據傳送至PID控制系統,使本平台具有300 × 300 mm之長行程定位能力、定位可達10奈米之高精度、可以34.5 mm/s之高速度移動以及可讓偏搖角補償達1 acesec之低角度誤差等特性。
A dual-axis long-stroke-nano-positioning stage was developed in this project. A traditional ball screw and linear guided way, provided by the PMI Co. Taiwan, was employed with a 3-DOF piezo-stage, 3-DOF measurement system and a PID closed-loop countroller for this stage. The working range of the stage can be up to 300 mm × 300mm with a resolution of 10 nm in each linear axis and 1 arcsec in the rotary axis.
