Abstract

PURPOSE:To smoothly perform a drain drying operation by a method wherein a splash-preventing net is arranged outside a rotary table surrounding the table, and the waterdrops splashed from a carrier plate are caught by the splash- preventing net. CONSTITUTION:A splash-preventing net 8 is arranged outside a rotary table 3 surrounding the table. Air is drawn into the hole 5a of a draining plate 5 by the rotation of the table 3, and the air is forcedly fed into the hole 5a by an air blasting pipe 6. A laminar stream, flowing toward the outer circumferential part from the center part of the table, is formed on the table 3, the water on the carrier plate is turned into waterdrops and they are separated from the carrier plate. Besides, the waterdrops splashed from the carrier plate are caught and collected by the net 8, and it is smoothly exhausted through the hole 7 located at the bottom part 1a of the container 1. As a result, a drain drying operation can be performed smoothly.

Reference numeral 1 in the figure is a box-shaped container, and the bottom 1 of this container I is
A rotation mechanism 2 is provided (spanned) in the bottom portion 1a by penetrating through the bottom portion 1a.
A rotary table 3 is installed on the rotary shaft of the rotary machine (I2).The rotary table 3 is used to rotate a carrier plate on which a polished wafer is attached. , semicircular notches 3a are formed at four equally spaced locations on the outer periphery, and eight protrusions 3b are formed on the outer periphery adjacent to each of the notches 3a. In addition, a support arm 4 is attached to the upper part of one end of the container I so as to be rotatable in the vertical direction.
A thin disc-shaped draining plate 5 having a hole 5a in the center is fixed to the. The draining plate 5 is placed on two sides of the rotary table 3 with a predetermined distance between them by maintaining a horizontal state. Furthermore, a blower pipe 6 supplies clean gas from the outside of the device to the top surface of the draining plate 5 in the state of wood wool.
It penetrates the bottom 1a of the container 1 and is attached to the container 1 so as to be freely rotatable in the horizontal direction. A port 7 for water recovery is connected to the bottom 1a of the container 1. Furthermore, within the container I, a cylindrical nylon net (splash prevention net) 8 is arranged between the rotary table 3 and the side wall 1b.

In the dryer configured as described above, when draining and drying the carrier plate, first rotate the support arm 4 upward to make the draining plate 5 stand up, and move the air pipe 6 in the horizontal direction. A carrier plate for drying is placed on the rotary table 3 in a state in which the carrier plate is rotated to avoid being removed from the rotary table 3. Next, after the draining plate 5 is folded down, the blower pipe 6 is rotated to be positioned above the draining plate 5.

Then, the rotation table 3 is rotated by the rotation mechanism 2.
Along with the filter, drain the water using the air pipe 6 h 5 J
) to supply air. In this case, by rotating the rotary table 30 times, air is sucked in through the hole 5a in the center of the drain plate 5, and the air is forced into the hole 5a of the drain plate 1-5 through the air pipe 6. As the water is supplied, a laminar flow is formed on the rotary table 3, flowing from the center toward the outer periphery, and the water that was attached to the carrier play 1 smoothly turns into droplets and flows onto the carrier. The water droplets that have separated from the plate are reliably blown to the outside of the carrier plate without adhering to the carrier plate again.Furthermore, the water and oil blown off from the gear rear plate are
It is captured by the nylon net 8, collected, and smoothly discharged through the port 7 of the bottom 1a of the container 2:1, and collides with the side wall 11) of the container 21), etc., as in the conventional case. It will not bounce back and stick to the carrier plate again.

"Effects of the Invention" As explained above, according to the present invention, a ricochet prevention net is arranged outside the rotary table on which the carrier plate is placed and rotated, surrounding the rotary table. Therefore, due to the high-speed rotation of the rotary table, the water droplets blown away from the carrier plate 1 are captured by the splash prevention net, so that they do not hit the carrier plate again and drain smoothly. What is the effect of being able to dry?
