Abstract:
An ion implanting apparatus comprising:an ion source for producing an ion beam; a process chamber for containing an object to be ion-implanted; a rotating body disposed and rotated in said process chamber; a holding means for holding said object to be ion-implanted with a spacing between an ion implanted area of said object to be ion-implanted and said holding means, said holding means being connected to said rotating body; an ion beam irradiation means for irradiating the ion beam from said ion source toward said object to be ion-implanted in said process chamber; and a heating means for heating said object to be ion-implanted in said process chamber, wherein said holding means includes a first holding portion holding said object to be ion-implanted in a state in contact with a part of a region at a periphery of said object to be ion-implanted, and blocks said object to be ion-implanted from moving toward an acting direction of a centrifugal force due to rotation of said rotating body during ion irradiation of said object by said ion beam irradiation means; and said holding means includes a second holding portion holding an end surface of the object to be ion-implanted at the periphery of said object to be ion-implanted to allow said object to be ion-implanted to move in a direction opposite to the acting direction of the centrifugal force due to rotation of said rotating body during ion irradiation of said object by said ion beam irradiation means.
