发明名称 Electron Beam Drawing Apparatus
摘要 The present invention provides an electron beam drawing apparatus which can easily perform beam adjustment and rotating center adjustment without increasing the size of the apparatus. The electron beam drawing apparatus includes an electron beam emitting unit which emits an electron beam, a rotary stage which rotatably supports a turntable for retaining a drawing object, and a sample stage which is supported by the turntable in a range including a rotating center of the turntable to retain an adjustment sample. A rotationally symmetrical pattern such as a concentric pattern and a radial pattern can be drawn in the drawing object by irradiating the drawing object with the electron beam during rotation of the turntable. Before the pattern is actually drawn in the drawing object, beam adjustment and rotating center adjustment are performed using an adjustment sample. The adjustment sample is retained by the sample stage, and the sample stage is supported by the turntable in the range including the rotating center of the turntable. Therefore, the beam adjustment and the rotating center adjustment can be performed using the adjustment sample supported by the turntable, and the different stage for placing the adjustment sample is not required, which allows the apparatus to be miniaturized.
