Patent number: 6433716Abstract: A data conversion device for converting analog data to digital data, or digital data to analog data, is composed of a data converter. and a mediator. Plural data groups are fed to the data converter that coverts the data, group by group, upon receipt of a request for converting a particular data group. If plural requests are simultaneously made, the mediator makes mediation among the plural requests to select a data group to be first converted and to set a priority order. A function uniquely corresponding to a combination of the plural requests is generated in the mediator, and the mediation is performed based on the generated function with reference to a preinstalled table showing a relation between the function and the request to be selected.Type: GrantFiled: February 14, 2001Date of Patent: August 13, 2002Assignee: Denso CorporationInventors: Soichiro Arai, Hirofumi Isomura

Patent number: 6072185Abstract: A device exposing a wafer to charged-particle beams in an exposure process generates a plurality of micro beams and controls deflection of each of the micro beams, relative to whether or not the micro beams reach the wafer, in accordance with control data. A data processing unit inserts data-position-adjustment data into the control data for each exposure. A first data-storage unit stores the control data, inserted with the data-position-adjustment data, and outputs the control data at a time of the exposure process. Storage positions of the control data in the first data-storage unit are adjusted by the data-position-adjustment data so that the control data can be continuously read from the first data-storage unit for maintaining a continuous exposure process.Type: GrantFiled: November 18, 1997Date of Patent: June 6, 2000Assignee: Fujitsu LimitedInventors: Soichiro Arai, Kenichi Miyazawa, Hidefumi Yabara, Hiroshi Yasuda

Patent number: 6064807Abstract: The present invention relates to an exposure method of a multi-beam type in which a stage mounting a sample to be exposed is continuously moved in a first direction, and charged-particle beams are controlled so as to form a desired beam shape as a whole, and in which a pattern is formed on the sample by deflecting the charged-particle beams by a main deflector and a sub deflector. Patterns to be drawn are divided into pattern data on a cell stripe basis which corresponds to an area which can be exposed when the sub deflector scans the charged-particle beams one time. The pattern data on the cell stripe basis is stored into a memory. Then, position data indicative of cell stripes is stored, in an exposure sequence, together with address information concerning the memory in which the pattern data is stored. The deflection amount data relating to the main deflector and the sub deflector is calculated from the position data. Patterns are drawn on the wafer by using the pattern data and the deflection amount data.Type: GrantFiled: May 24, 1996Date of Patent: May 16, 2000Assignee: Fujitsu LimitedInventors: Soichiro Arai, Junichi Kai, Hiroshi Yasuda, Shunsuke Hueki, Yoshihisa Oae

Patent number: 6057907Abstract: Before figure data are expanded into a bitmap, a checksum is calculated in unit of bitmap data corresponding to a cell stripe of scanning over which continuous exposure is possible. When the checksum is calculated after expanding the data into the bitmap, the interim calculation result of refocus values is used. In exposure, exposing k number of sub rectangular areas by repeating a sub scanning k number of times, jumping a deflection by a main deflector toward an center of remaining sub rectangular areas whose number is (p-k) inside a main rectangular areas and exposing remained (p-k) number of the sub rectangular areas by repeating the sub scanning (p-k) times after the jumping is settled. In an amplifier & low pass filter for supplying a drive voltage to a sub deflector, the cutoff frequency is lowed during flyback in a sawtooth waveform without changing an amplification factor.Type: GrantFiled: August 12, 1998Date of Patent: May 2, 2000Assignee: Fujitsu LimitedInventors: Takamasa Satoh, Soichiro Arai, Kenichi Miyazawa, Yoshihisa Ooaeh, Junichi Kai, Hiroshi Yasuda
