    • A control method for a target supply device may employ a target supply device, provided in an EUV light generation apparatus including an image sensor, that includes a target generator having a nozzle and configured to hold a target material and a pressure control unit configured to control a pressure within the target generator, and the method may include outputting the target material in the target generator from a nozzle hole in the nozzle by pressurizing the interior of the target generator using the pressure control unit, determining whether or not a difference between an output direction of the target material outputted from the nozzle hole that is detected by the image sensor and a set direction is within a predetermined range, and holding the pressure in the target generator using the pressure control unit until the difference falls within the predetermined range.
    • 目标供给装置的控制方法可以采用在包括图像传感器的EUV光发生装置中设置的目标供给装置,所述图像传感器包括具有喷嘴的目标发生器,并且被配置为保持目标材料,压力控制单元被配置为控制 目标发电机内的压力,并且该方法可以包括通过使用压力控制单元对目标发电机的内部进行加压,从喷嘴中的喷嘴孔输出目标发电机中的目标材料,确定输出 从由图像传感器检测到的喷嘴孔输出的目标材料的方向和设定方向在预定范围内,并且使用压力控制单元保持在目标发生器中的压力,直到差落在预定范围内。
