    • PURPOSE: An electron beam writing device and an electron beam writing method reduce the drift of an electron beam due to reflected electrons or secondary electrons by applying a positive voltage to an electrostatic lens. CONSTITUTION: A sample (216) is placed on an XY stage (105). An electron body tube (102) includes an electron gun (201) and a lens. The lens includes an electrode aligned in an axial direction of an electron beam (200). A shielding plate (211) is placed between the XY stage and the electron body tube, and reduces reflected electrons or secondary electrons which are generated by irradiating the electron beam to the sample. An electrostatic lens (210) is placed immediately above the shielding plate and changes a focal position of the electron beam. A voltage supply unit (135) applies a positive voltage constantly to the electrostatic lens.

    • 目的:电子束写入装置和电子束写入方法通过向静电透镜施加正电压来减少由反射电子或二次电子引起的电子束漂移。 构成:样品(216)放置在XY台(105)上。 电子体管(102)包括电子枪(201)和透镜。 透镜包括沿电子束(200)的轴向排列的电极。 屏蔽板(211)被放置在XY平台和电子体管之间,并且减少通过向样品照射电子束而产生的反射电子或二次电子。 静电透镜(210)被放置在屏蔽板的正上方并改变电子束的焦点位置。 电压供给单元(135)将恒定的正电压施加到静电透镜。 (附图标记)(110)控制计算器; (112)写入数据处理单元; (120)偏转控制电路; (121)变形量计算器; (124)偏转信号发生单元; (130,131,132,133)DAC放大器单元; (135)供电装置; (143)检测器; (145)激光长度测量单元
