Abstract:
An ion implanting apparatus comprising:an ion source for producing an ion beam; a process chamber for containing a plurality of wafers to be ion-implanted; a rotating body disposed and rotated in the process chamber; a plurality of wafer holders fixed to the rotating body to support the wafers in an inclined state to a rotating plane of the rotating body; and ion beam irradiation means for irradiating the ion beam from the ion source toward the wafers to be implanted in the process chamber, wherein the wafer holders include a first supporting portion supporting the wafers to be ion-implanted, in a state in contact with a part of a region at a periphery of each wafer to be ion-implanted, and so as to block the wafers to be ion-implanted from moving toward an acting direction of centrifugal force due to rotation of the rotating body during ion irradiation of the wafers by the ion beam irradiation means; and the wafer holders include a second supporting portion supporting an end of each wafer to be ion-implanted, so as to raise the wafers against the first supporting portion, the second supporting portion being supported by a spring attached to the wafer holders.
