    摘要: An exposure method forms a plurality of patterns on a substrate, which is set on a stage of an exposure apparatus, through at least one mask. The method equalizes first positional linear error components of a pattern to be formed by the mask on a first coordinate system defined on the substrate to second positional linear error components of the pattern on a second coordinate system on which the stage is moved, by correcting coordinates for moving the stage on the second coordinate system. The method is capable of aligning the boundaries of patterns with each other on the substrate, to leave only positional linear error components on the patterns. These positional linear error components are removable to leave minimum random residual errors on the patterns, and therefore, the patterns on the substrate are precisely at specified positions.

    摘要: A method of manufacturing a semiconductor device, light is applied through the cell patterns made in master masks, thereby transferring the cell patterns to, and forming the cell patterns on, a wafer. On the basis of layout data representing a layout diagram of the semiconductor device, the pattern data of the device is divided along the boundaries of the function blocks of the device, generating pattern data items. Master masks are prepared in accordance with the pattern data items. Light is applied to the wafer, first through the master mask and then through the master mask. The cell patterns made in the master masks are transferred to the wafer.

    摘要: There is disclosed a method for inspecting a defect in a photomask which is produced by using a graphic data, that matches mask data or is produced by subjecting mask data to correction of a process conversion difference relating to at least a line width. The method includes the following steps. Inspection data is produced by correcting a pattern of mask data so as to substantially match a planar shape of a pattern of a photomask to be produced by using the graphic data. A pattern of a produced photomask is compared with a pattern of the inspection data. Portions where planar shapes of the pattern of the inspection data and the pattern of the produced photomask do not match are extracted. A defect is distinguished from the portions where the planer shapes do not match.
