Publication number: 20030105843Abstract: In a multi-computer system having a plurality of computers, an input/output device configuration definition table and an input/output device configuration reference table are adapted to be collectively managed. A configuration management program manages the configuration definition of all input/output devices of a plurality of computers by using the input/output device configuration definition table, and generates a changed data file when an input/output device configuration is changed. Dynamic system alteration is effected by changing the contents of the input/output device configuration reference table stored in a shared memory, in accordance with the changed data file. The input/output device configuration definition table and the input/output device configuration reference table each have an input/output device information part and an input/output device connection information part arranged in a matrix form to allow addition/deletion of an input/output device and a computer.Type: ApplicationFiled: January 7, 2003Publication date: June 5, 2003Inventors: Toshio Yamaguchi, Kazuo Imai, Masatoshi Haraguchi

Patent number: 6319642Abstract: A pattern lithography system for lithographing a pattern with reference to a pattern data by deflecting an electron beam includes a controller, an extracting unit, a dividing unit, and an expansion unit. The controller analyzes the pattern data and determines stripes of the pattern to be successively lithographed. The extracting unit extracts parts of the pattern data corresponding to stripes of the pattern in response to commands from the controller and sends the data to the dividing unit. The dividing unit divides the part of the pattern data into a plurality of sub-patterns. The sub-patterns are sized smaller than a minimum deflection range of the electron beam. The expanding unit expands the sub-patterns in accordance with a command from the controller to produce stripe data for driving a lithographing unit to lithograph the stripe. Stripes may have at least one sub-pattern in common such that multiple lithography is performed.Type: GrantFiled: March 23, 1999Date of Patent: November 20, 2001Assignee: Kabushiki Kaisha ToshibaInventors: Shigehiro Hara, Eiji Murakami, Hitoshi Higurashi, Toshio Yamaguchi, Kazuto Matsuki, Souji Koikari, Shuichi Tamamushi, Kazuyuki Okuzono

Patent number: 5760410Abstract: An electron beam lithography apparatus is provided for drawing a exposure pattern on a sample by dividing the exposure pattern into a plurality of pattern elements and individually directing the electron beam to the sample at the pattern element. The size of the pattern element is adjusted in accordance with a gradient of a spatial variation of a back scattering dose. By doing so, it is possible to suppress distortion at the exposure area of one shot and to suppress an uneven edge of an exposure area row. If the size of the pattern element is made uniformly smaller, the drawing throughput is markedly lowered. The sizes of the pattern element varies in accordance with the gradient of a spatial variation of the back scattering dose and it is, therefore, possible to suppress a fall in the drawing throughput.Type: GrantFiled: April 24, 1997Date of Patent: June 2, 1998Assignee: Kabushiki Kaisha ToshibaInventors: Kazuto Matsuki, Shuichi Tamamushi, Toshio Yamaguchi, Ryoichi Yoshikawa
