To provide a pattern generator for solving the problem of stitching error.
An apparatus and method of forming a pattern on a work piece are provided. The apparatus includes a light source for radiating a wide range of light from extreme ultraviolet ray to infrared ray; a spatial light modulator configured to be mounted on a precision stage, to have many modulation elements, and to be illuminated by the radiated light; a projecting system for forming the image of the spatial light modulator on the work piece; an electric data processing and transmitting system for receiving the digital expression of the pattern to be written to modulate the pattern to a modulation signal, and to supply the modulated signal to the space light modulator; a high precision mechanical system for mutually positioning the work piece and/or projection system; an electronic control system for printing a pattern to the work piece by regulating the position of the work piece, the supply of modulated signal to the spatial light modulator, and radiation intensity; and a means for rotating the system of coordinate of the pattern to be printed against the system of coordinate of the work piece on a positioning stage.
