摘要： Disclosed are a system for compensating dynamic and thermal deformity errors of a linear motion single-plane gantry stage in real time, a stage apparatus using the system, and manufacturing, measuring and inspecting apparatuses using the system. The system includes: a first two-dimensional position measuring unit arranged in each of two linear edge beams respectively positioned in both sides of the linear motion single-plane gantry stage for measuring the position of an X-axially moving gantry beam to provide a feedback of an X-axial motion thereof; a second two-dimensional position measuring unit for measuring the position of a Y-axially moving slider moving on the X-axially moving gantry beam to provide a feedback of a Y-axial motion thereof; a thermal fixing point provided as a thermal reference for measuring a thermal expansion of the X-axially moving gantry beam; and a compensation control unit for controlling an error motion of the linear motion single-plane gantry stage in real time by measuring dynamic and thermal deformity errors based on the data received from the first and the second two-dimensional position measuring unit (FIG. 1).
