PURPOSE: A micro-stage having a piezo resistance displacement sensor and a chevron beam structure is provided to amplify displacement of a column driver having a large shift through the chevron beam structure extended from four sides of a platform to vertical and horizontal directions. CONSTITUTION: A micro-stage having a piezo resistance displacement sensor and a chevron beam structure includes a platform(100), an extension beam(200), a chevron beam(300), a piezo resistance displacement sensor, and a column driver(400). The platform has a square shape, and a sample is placed in the center of the platform. The extension beam is extended from one side of the platform. The extension beam includes an electrode for preventing the extension beam from being bent to a specific axis. The chevron beam has a 'V' shape, and the center thereof is connected to the extension beam. The chevron beam draws the extension beam to drive the platform when the piezo resistance displacement sensor is driven. The piezo resistance displacement sensor is driven to a particular direction by generating Joule heat when a voltage is applied thereto. The piezo resistance displacement sensor comprises two integrated column drivers.
