Patent number: 5892237Abstract: In a charged particle beam exposure method and an apparatus therefor, wherein the intensity of the charged particle beam used for irradiation is increased to a maximum to improve a throughput for an exposure procedure, accordingly, the temperature of a sample, such as a wafer, is elevated and thermal expansion occurs. The thermal expansion that occurs has reproducibility based on the intensity of the projected charged particle beam. Therefore, a coefficient of thermal expansion is detected by monitoring the intensity of the projected charged particle beam. A shifting distance for each irradiation position which is acquired from the thermal expansion is added as a compensation value for deflection of the charged particle beam, to provide an accurate exposure procedure.Type: GrantFiled: March 11, 1997Date of Patent: April 6, 1999Assignee: Fujitsu LimitedInventors: Kenichi Kawakami, Hiroshi Yasuda, Akio Yamada, Tatsuro Ohkawa, Mitsuhiro Nakano, Atsushi Saito, Yoshihisa Ooae
