In LSI manufacturing, these clean benches are installed inside a clean room, which is a building, and are installed in order to locally create a cleaner area than the clean room.
The duct adhesion to the wafer can be minimized by covering the entire apparatus with the clean bench or by using the area where the clean bench is provided as the working area. It is also possible to install a clean bench in a normal building that is not clean in other fields.

When attempting to move a wafer between devices, the wafer will exit the most cleaned area and pass through a slightly dustier area, which is traditionally based on the concept of a clean tunnel or clean booth. A general method is to clean the entire space and ensure the highest cleanliness even when moving between devices. The disadvantage of this method is that it leads to an increase in the cost of equipment and power, and there has been a demand for a method that can obtain the same degree of cleanliness with a cheaper method.

(Embodiment) FIG. 1 shows a configuration of an embodiment of the present invention, (a) is a side view and (b) is a plan view. The overall size and weight is such that it can be pushed and moved by humans, for example 400 mm x 4
If you use something like 00mm x 1200mm, it will be easy to handle. In FIG. 1, 1 is a pre-filter, 2 is a blower, and 3 is a main filter. By operating the blower 2, outside air is taken in through the pre-filter 1 and purified air is passed through the main filter 3 at the lower part. Clean space area 4
Send to. The lower clean space region 4 is made by this clean bench, and a processed product such as a semiconductor wafer which is difficult to duct is put in the clean space region 4 to secure cleanliness during the process. The lower clean space region 4 is a partition plate 5 for placing articles.
To provide. The partition plate 5 was provided with punching holes for uniforming the wind direction, and an air vent hole 6 was provided at the bottom of the bench in order to allow the wind to escape. A door 7 is provided for loading and unloading articles into and from the clean space area 4. However, if the door 7 is provided on two opposite surfaces, the clean bench can be placed directly on the front surface of the apparatus transfer section so that it can be installed from one side. An operator can insert an item into the device without reaching in and exposing the item to unclean air. A rechargeable battery 8 is installed below the clean space region 4 to supply power to the blower 2.
In addition, since the wheels 9 are provided at the bottom of the clean bench,
Can be easily moved.

(Effect of the Invention) Since the present invention is a simple portable clean bench for protecting the wafer cleanliness, unlike the conventional case, when the wafer is moved between the devices protected by the fixed clean bench, the wafer has a lot of dust. Since it does not pass through the area and does not necessarily require a large clean tunnel or clean booth, the clean room facility can be simplified and the power cost can be reduced.
