Patent number: 6565419Abstract: Disclosed is a method of readily removing particles from a stage, that is, a stage particle removing method for removing particles from a stage that holds a planar workpiece. A resin film is placed on the stage, and collected from the stage. The resin film is coated over at least one surface of the planar workpiece such as a semiconductor wafer or glass substrate. The resin film is brought into contact with the stage. The resin film may not be coated over the planar workpiece itself but may be coated over a dedicated planar piece shaped similarly to the planar workpiece, for example, a thin metallic plate that is very smooth. The used resin film is peeled off from the planar workpiece or dedicated planar piece, and the resin film is coated again. Thus, the planar workpiece or dedicated planar piece can be reused.Type: GrantFiled: February 3, 2000Date of Patent: May 20, 2003Assignees: Advantest Corporation, Fujitsu LimitedInventors: Naoki Nishio, Kazushi Ishida, Yukio Takigawa, Ei Yano

Patent number: 6046459Abstract: With using one scanning stage 19 where a plurality of wafers 16A to 16E is mounted through wafer holders 20A to 20E and balancing stage 21 disposed below scanning stage 19, scanning stage 19 is scanned based on exposure data common to a plurality of charged particle beam exposure apparatus 10A to 10E, and balancing stage 21 is scanned so that barycenter G of scanning stage 19 and balancing stage 21 becomes a fixed point. The positions of reflecting mirrors 70L and 70R secured to stage 19 are measured and based on their values, the expansion/contraction ratio of stage 19 and the positions of samples 16A to 16E are calculated to obtain deviation of the positions from target positions. Stage 19 is modeled such that rigid areas 19A to 19E are loosely connected, and for each area, the positions of three points are measured to calculate deviation of the exposure target position due to rotation of each ridged area. These deviations are corrected by deflectors 18A to 18D.Type: GrantFiled: September 23, 1999Date of Patent: April 4, 2000Assignees: Fujitsu Limited, Advantest CorporationInventors: Nobuyuki Yasutake, Yoshihisa Ooae, Kazushi Ishida, Hiroshi Yasuda, Akiyoshi Tsuda, Hitoshi Tanaka
