Abstract

PURPOSE:To incorporate the titled drier easily to an automatic treating process, and to dry a wafer readily by bringing the wafer into contact with and holding it to a stopper with the revolution of a rotary stage. CONSTITUTION:A semiconductor wafer 1 is placed eccentrically on a rotary stage 12 while taking a distance (e) between the central point of the stage and the central point of the semiconductor wafer, and three stoppers 13 are fitted in the direction of positional displacement of the semiconductor wafer 1. When the semiconductor wafer 1 having a 5 inch diameter is placed on the rotary stage 12 having a 150mm. diameter, the distance (e) is brought to 5mm.. Consequently, speed is increased slowly from the number of revolution of several dozen RPM up to the number of revolution of 5,000RPM first, and speed is reduced gradually and stopped lastly. According to such a usage, the semiconductor wafer can be held only by fitting the stoppers 13 only at one side end of the fringe of the rotary stage 12 because the semiconductor wafer is pushed against the stoppers and held by centrifugal force by revolution.

(b) Prior Art and Problems When manufacturing semiconductor devices, chemical treatments are repeatedly performed in the wafer process of semiconductor wafers, and cleaning with pure water or alcohol is performed each time. Further, after cleaning, a spin dryer is used to shake off the cleaning liquid in order to quickly remove the cleaning liquid. This is because if the cleaning liquid remains on the surface of the semiconductor wafer for a long time, it is likely to be oxidized or have dust attached thereto.

No. 11m shows a schematic cross-sectional view of such a conventional spin dryer. 1 is a semiconductor wafer, 2 is a rotating stage,
The rotating stage 2 is provided with a plurality of stoppers 3 on its periphery to hold the semiconductor wafer 1, and the semiconductor wafer 1 is rotated together with the stage 2 at high speed (approximately 500 ORPM) and dried by shaking off moisture. . In addition, dry gas (N2 gas, etc.) is blown from above in order to dry it.

By the way, such a conventional spin dryer is provided with a large number of stoppers 3 around the entire periphery of the rotating stage 2, so if the spin dryer is incorporated into an automatic processing process (in-line process), it can be easily attached to and removed from the stage. Rather, some mechanical means is required for this purpose. Therefore, there is a drawback that the non-contact conveyance system (for example, air bearing) which has been used recently cannot be used.

There is also a vacuum chuck method in which a semiconductor wafer is vacuum-suctioned onto a stage and rotated, but the disadvantage of this method is that it is difficult to dry the suction surface.

(dl) Structure of the Invention The object of the invention is that the center of the wafer and the rotation axis of the rotation stage are arranged eccentrically, and a plurality of stoppers are provided only at the periphery of the rotation stage in the eccentric direction from the center of the wafer. This can be achieved by a spin dryer having a structure in which the wafer is held in contact with the stopper as the stage rotates.

FIG. 2 is a schematic sectional view of a spin dryer according to the present invention;
FIG. 3 shows its plan view. As shown in the figure, the semiconductor wafer 1 is placed on the rotating stage 12 with a distance e between the center point of the stage and the center point of the semiconductor wafer.
The semiconductor wafer 1 is placed eccentrically, and three stoppers 13 are provided in the direction in which the semiconductor wafer 1 is displaced. When a semiconductor wafer 1 with a diameter of 5 inches is placed on a rotation stage 12 with a diameter of 150 m++, the interval e is set to 51, for example. Thus, the rotation speed is first gradually increased from a few 1 ORPM to 5000 PPM, then gradually lowered and finally stopped. When used in this manner, the semiconductor wafer can be held by simply providing the stopper 13 at one side end of the periphery of the rotary stage 12. This is because the semiconductor wafer is held against the stopper by the centrifugal force caused by the rotation.

Then, for example, as shown in FIG.
2 and the upper surface of the transfer stage 14 are arranged in parallel and coincide with each other, and the transfer stage 14 is fed from the right transfer stage 14 onto the rotary stage 12 by an air bearing or water bearing, and then, after dry processing, the transfer stage 1 is transferred to the left.
4 can be sent out. At this time, the stop position of the rotary stage 12 is controlled using electrical signals. That is, for feeding from the right, the stopper 13 is placed on the left to stop the rotation stage 12, and for feeding from the left, the stopper 13 is placed on the right and the rotation stage 12 is stopped.
