Abstract:
A charged-particle beam exposure apparatus for drawing a pattern on an object to be exposed using a charged-particle beam, comprising:a plurality of driving elements for drawing the pattern on the object while scanning the object with the charged-particle beam; a plurality of driving data memories for storing a plurality of time-series driving data strings for respectively driving said plurality of driving elements; and a clock pattern memory for storing a plurality of operation command data strings obtained by aligning operation commands and non-operation commands in time-series, the operation commands and the non-operation commands constituting each operation command data string being sequentially supplied to a corresponding driving data memory of said plurality of driving data memories, wherein each of said plurality of driving data memory sequentially supplies data constituting the time-series driving data string to a corresponding driving element of said plurality of driving elements in accordance with the operation commands supplied by said clock pattern memory.
