Abstract

A reticle transport system having a magnetically levitated transportation stage is disclosed. Such a system may be suitable for use in vacuum environments, for example, ultra-clean vacuum environments. A magnetic levitated linear motor functions to propel the transportation stage in a linear direction along a defined axis of travel and to magnetically levitate the transportation stage.
