摘要:
A mover device and an ion implanter apparatus having a processing base that reciprocates at a high speed without undesirable noise and vibration are provided. The mover device includes: a fixed base; a movable base that is linearly movable with respect to the fixed base; a processing base that is linearly movable with respect to the movable base; a main linear motor that generates a moving force to move the processing base with respect to the movable base, thereby moving the processing base with respect to the fixed base; and a velocity control unit that controls the moving velocity of the processing base with respect to the fixed base. In this mover device, the movable base is moved by virtue of a reaction force caused by the moving force to move the processing base.

An ion implantation device is equipped with a high-speed driving device which causes rotation of a disk that supports semiconductor wafers around its outer periphery. A center position of the disk is the axis of the high-speed rotation. A low-speed driving device causes relative movement of the disk in a radial direction. The ion implantation device calculates the movement speed of the low-speed driving device with reference to different spacings between wafers about the outer periphery and the distance from the center of the disk to the ion implantation position and controls the low speed scan speed so that ions are uniformly implanted into the wafers.

Embodiments of the invention are directed to a method of controlling a mover device The method includes generating a moving force from a moving force generating unit to move a processing base with respect to a movable base, thereby moving the processing base with respect to a fixed base as a result of the movement of the processing base with respect to the movable base; moving the movable base on the fixed base in the opposite direction to the moving direction of the processing base by virtue of a reaction force caused by the moving force generated from the moving force generating unit to move the processing base, so that the movable base moves in the opposite direction to the moving direction of the processing base on the fixed base. The method further includes controlling the moving velocity of the processing base with respect to the fixed base.

A method of controlling a mover device that includes: a fixed base; a movable base that is moveable in a linear direction with respect to the fixed base; a processing base that is movable in a linear direction with respect to the movable base, the linear direction being in parallel with the linear moving direction of the movable base; and a moving force generating unit that is provided between the processing base and the movable base, and forms a main moving unit in cooperation with the processing base and the movable base, includes the steps of: generating a moving force from the moving force generating unit to move the processing base with respect to the movable base, thereby moving the processing base with respect to the fixed base as a result of the movement of the processing base with respect to the movable base; moving the movable base on the fixed base in the opposite direction to the moving direction of the processing base by virtue of a reaction force caused by the moving force generated from the moving force generating unit to move the processing base, so that the movable base moves in the opposite direction to the moving direction of the processing base on the fixed base; and controlling the moving velocity of the processing base with respect to the fixed base.
