【Abstract】 At present, the line-space of super large scale integrated circuit (SLSI) has been less than about 0.1μm. Manufacturing the SLSI, to expose 300mm silicon wafer, a step-and-scan photolithography has to have a long stroke within 400mm,and the system precision of localization and movement is required from several nm to dozens of nm, furthermore, it must have good dynamic answer performance of velocity, acceleration and the variety of acceleration. The existing multi-coordinate motion system, with ordinary transmission parts, is hardly to meet the requirements. So, a multi-coordinate motion system with high performance, high speed and super precision is becoming the throat (key technology) of SLSI manufacture. A structure design of 6-coordinate system exposure chuck has been introduced in detail in this paper. The exposure chuck system is the key sub-system of 0.1μm lithography. LinerMotor, voice coil motor and lorenz plane motor are adopted to constitute multilevel execution parts to ensure the realization of high performance, high speed and super precision.更多还原
