Definitions
- the present invention relates to a cleaning member for removing fine foreign matters, a transport member with a cleaning function, and a tiling method for a substrate processing apparatus using the transport member with a cleaning function. More specifically, for example, a cleaning member for removing foreign matter from a substrate or apparatus that dislikes fine foreign matter, such as a semiconductor, a flat panel display, a printed substrate, and a substrate processing apparatus, and a cleaning function having the cleaning member.
- the present invention relates to a transport member and a cleaning method for a substrate processing apparatus using the transport member with a cleaning function.
- each transport system and the substrate are transported without force. At that time, if foreign matter adheres to the substrate or the transport system, the subsequent substrate will be contaminated one after another. Therefore, it is necessary to periodically stop the apparatus and perform a cleaning process. As a result, there is a problem that the operation rate of the substrate processing apparatus is lowered and a great amount of labor is required for the cleaning process of the substrate processing apparatus.
- Patent Document 2 there has been proposed a method (see Patent Document 2) for cleaning and removing foreign substances adhering to the processing apparatus by transporting the substrate to which the adhesive substance is fixed as a cleaning member into the substrate processing apparatus. ing.
- this method is also excellent in the removal of foreign matters, so that the operation rate of the substrate processing apparatus is reduced. All of the problems that a great deal of labor is required for cleaning the substrate processing apparatus can be solved.
- the method of cleaning and removing foreign substances with a cleaning member having an adhesive substance is an excellent method for effectively removing foreign substances, but the adhesive substance strongly adheres to the tailing site. There is a possibility that a problem that it is not peeled off too much may occur, or a problem that the adhesive remains in the cleaning portion and is contaminated. In addition, when the adhesive strength is reduced in order to prevent adhesive residue, there is a problem in that it is inferior in dust removal of important foreign matter.
- the method of wiping alcohol with a cloth soaked in alcohol has a problem that it is inferior in dust removal, such as leaving foreign matter and unevenness in removing foreign matter. It was.

- Patent Document 3 Japanese Patent Laid-Open No. 2004-63669
- the present inventors have provided a plurality of columnar structure protrusions having a specific aspect ratio on the surface of the cleaning layer provided in the cleaning member. As a result, the present inventors have found that the above problems can be solved, and have completed the present invention.
- the cleaning member of the present invention is a cleaning member having a cleaning layer having a plurality of projections having a columnar structure on the surface, and the aspect ratio of the projections of the columnar structure is 5 or more.
- the length of the protruding portion of the convex portion of the columnar structure is equal to or greater than lOOnm.
