Description of the Invention (//) The electron beams of the axis electronic lens 24 each adjust the focus through several electron beams located at Several holes of the electrode array 26 are blanked. The blanking electrode array control unit 86 is used to control whether a voltage is applied to the deflection electrodes provided near the small holes of the blanking electrode array 26. The blanking electrode array 26 switches whether or not the electron beam is irradiated according to the voltage applied to the deflection electrodes. On wafer 44. The unbiased electron beams passing through the blanking electrode array 26 pass through the third multi-axis electron lens 34. The third multi-axis electron lens 34 reduces the electron diameter of the electron beam passing through the third multi-axis electron lens 34, and the reduced electron beam passes through an opening located on the electron beam shielding member 28. The electron beam shielding member 2'8 shields the deflected electron beam by the blanking electrode array 26. The electron beam passing through the electron beam shielding member 28 is incident on the fourth multi-axis electron lens 36. The fourth multi-axis electron lens 36 independently focuses the incident electron beams, and the electron beam whose focus is adjusted by the fourth multi-axis electron lens 36 enters the deflection unit 38. The deflection control unit 92 controls a plurality of deflectors located in the deflection unit 38 based on the correction chirp calculated by the calculation unit 132, and independently deviates each electron beam incident on the deflection unit 38 to a position to be irradiated on the wafer 44. The fifth multi-axis electron lens 52 is used to adjust the focus of each electron beam passing through the fifth multi-axis electron lens 52 on the wafer 44. Instead, the wafer should be irradiated, and each electron beam having a cross-sectional shape should be irradiated on the position of the wafer to be irradiated. In the exposure process, the wafer stage driving unit 48 preferably moves the wafer stage 46 continuously in a certain direction according to an instruction from the wafer stage control unit 96, and then cooperates with the movement of the wafer to form the cross-sectional shape of the electron beam on the wafer.

Description of the invention (/ 2) The shape should be irradiated to determine the small hole through which the electron beam that should be irradiated on the wafer 44 passes. Then, according to the deflection section 38, each electron beam is deflected to the position where the wafer should be irradiated, so that a desired crystal pattern can be exposed on the wafer. Fig. 2 is an electron beam exposure related to this embodiment. The full diagram of the operation flow of the device 100 is started at S10. In the wafer stage position correction stage (S20), the position of the wafer stage 46 marked with the sfi section 56 is being set. In the irradiation position formation stage (S30), All electron beams are irradiated on the marking portion 56 In order to detect the irradiation positions of all the electron beams, the irradiation positions of the respective electron beams are corrected. In the exposure processing stage (S40), the correction is determined based on the wafer stage position correction stage (S20) and the irradiation position correction stage (S30).値 to perform a predetermined number of exposure processes. At S50, it is determined whether the required number of exposure processes has ended. At S50, it is determined that the required number of exposure processes has not been completed. Then, the predetermined electrons are detected at the irradiation position correction stage (S60). The irradiation position of the beam is used to correct the irradiation position of the electron beam used in the exposure process. Using the correction beams determined in the wafer stage position correction stage (S20) and the irradiation position correction stage (S30), the detected electrons are detected. The beam is irradiated on the marking unit 56 to calculate a correction frame for correcting the offset of the irradiation positions of a plurality of electron beams. Then, in the exposure processing stage (S40), the determination is performed based on the correction frame calculated in the irradiation position correction stage (S6 ()). If it is determined in S50 that the required number of exposure processes have been completed, then the process ends in S70. The correction step is performed via the irradiation position. (S60) When correcting the irradiation position of the electron beam, it is best to do it in batches or slices. Figure 3 is the irradiation position correction stage (S60).

The necessary electron beam irradiation position is determined in S100. Whether the coordinates of the detected electron beam have been detected. When it is determined in S100 that the necessary coordinates of the electron beam irradiation position are not detected, the process returns to the irradiation position detection stage (S80), and the coordinates of other detection electron beam irradiation positions are detected. Then, the coordinates of the detected irradiation position are stored in the irradiation position storage stage (S90). When it is determined that the coordinates of the necessary electron beam irradiation position have been detected in S100, the correction unit calculation stage (SU0) is based on the detected The calculated coordinates are used to calculate the correction position of the electron beam irradiation position other than the electron beam used for detection. In this embodiment, the memory 134 of the collective control unit 130 stores each electron beam irradiation position. The positional relationship of the electron beam exposure device 100 can also be used to calculate the corrections of other electron beam irradiation positions using the positional relationship stored in the memory at the correction stage calculation stage (sno).
