    • A relatively light and generally resinous hermetically sealed container is provided for accommodating, supporting and transporting a precision sheet (semi-)product, such as a photomask, safely and in an airtight manner without exerting an inappropriate stress thereto, which precision sheet (semi-)product has such a large planar size that encounters an extreme difficulty in integral resin molding of a half of a container therefor. The container includes a main body and a lid member which are generally symmetrical with each other and respectively have sealing peripheries to be abutted to each other. Each of the main body and the lid member includes a plurality of resin-sheets which are disposed in a plane, abutted to each other at an intermediate joint boundary therebetween and joined with each other at the joint boundary. A reinforcing metal belt member is disposed from outside along the joint boundary and hermetically bolted to the resin sheets.

    • A variably shaped beam EB writing system which draws a pattern, comprises a recognition module, an adjustment module, and a drawing module. The recognition module recognizes at least one of a first length unit to specify a pattern length and a first position unit to specify a position described to a pattern data. The adjustment module adjusts at least one of a second length unit to specify a pattern length which is drawn by the variably shaped beam EB writing system and a second position unit to specify a position thereof to a value of which at least one of the first length unit and the first position unit are divided by a natural number. The drawing module draws a predetermined pattern based on at least one of the second length unit and the second position unit adjusted by the adjustment module.

    • In a method of generating from design data the exposure data necessary for a multistage-deflection charged beam exposure device that has a main deflector and a sub-deflector and forms a pattern, before a shape larger than the size of a minimum subfield area is divided during the generation of subfield exposure data, the process of dividing the shape into shapes equal to or smaller than the size of a subfield area and restructuring the shape is performed. Moreover, after the overlapping cell arrays in the design data are changed into a cell array structure preventing the cell arrays from overlapping, the resulting cell arrays are subjected to a hierarchical shape data operation process and a formatting process, including compression, subfield division, and frame division. This makes it possible to reduce the amount of data supplied without increasing the time required to converting the design data into exposure data supplied to the charged beam exposure device.
    • 在从设计数据生成的方法中,在具有主偏转器和副偏转器并形成图案的多级偏转带电束曝光装置所需的曝光数据在大于最小子场区域的尺寸的形状之前被划分 在产生子场曝光数据期间,执行将形状分割成等于或小于子场区域的尺寸并重构形状的形状的处理。 此外,在将设计数据中的重叠单元阵列改变为防止单元阵列重叠的单元阵列结构之后,对所得单元阵列进行分层形状数据操作处理和格式化处理,包括压缩,子场划分和 框架划分。 这使得可以减少提供的数据量,而不需要将设计数据转换成提供给带电束的曝光装置的曝光数据所需的时间。
