摘要： An ion implantation apparatus includes a beam scanner, a beam measurement unit that is able to measure an ion irradiation amount distribution in a beam scanning direction at a wafer position, and a control unit that outputs a control waveform to the beam scanner for scanning an ion beam. The control unit includes an output unit that outputs a reference control waveform to the beam scanner, an acquisition unit that acquires the ion irradiation amount distribution measured for the ion beam scanned based on the reference control waveform from a beam measurement unit, and a generation unit that generates a correction control waveform by using the acquired ion irradiation amount distribution. The control unit outputs the correction control waveform so that the ion irradiation amount distribution becomes a target distribution and the ion irradiation amount distribution per unit time becomes a target value.

摘要： An ion implantation method includes measuring a beam energy of an ion beam that is generated by a high-energy multistage linear acceleration unit operating in accordance with a tentative high-frequency parameter, adjusting a value of the high-frequency parameter based on the measured beam energy, and performing ion implantation by using the ion beam generated by the high-energy multistage linear acceleration unit operating in accordance with the adjusted high-frequency parameter. The tentative high-frequency parameter provides a value different from a value of the high-frequency parameter for achieving a maximum acceleration in design to a high-frequency resonator in a part of stages including at least a most downstream stage. The adjusting includes changing at least one of a voltage amplitude and a phase set for the high-frequency resonator in the part including the at least most downstream stage.
