Filed: 1988-07-21
Abstract: PURPOSE:To reduce the memory capacity of an exposure device while facilitating the positive-negative inversion of patterns by a method wherein the beam are scanned in the same way as that of the vector scanning making reference to vector data processed from raster data. CONSTITUTION:A host computer 2 converts any gerber data read out of a magnetic tape 1 into raster data and after deciding if the data are to be inverted to negative or positive, the vector data are processed sideways from the raster data. After finishing the conversion, the host computer 2 transmits the vector data to an exposure device 4. The deflection signals shifted from the starting position X0 to the position X1 wait for the response time of a system and, after the beams are turned ON, to be shifted to the next position X2 where the beams are turned OFF and the deflection signals are shifted to the next position X3. The Y coordinates of the positions X2 and X3 are the same. Later, the same procedures are repeated to draw pictures on the specified patterns. At this time, the vector data are required simply of the coordinate of fulcrum and the length so that the memory 6 capacity of the exposure device 4 may be reduced while facilitating the negative and positive inversion.
