Problems solved by technology

However, for this cleaning wafer, since the foreign matter is retained and removed by the voids of the dot pattern, only foreign matter having a particle diameter of about tens of microns can be removed, and it is difficult to sufficiently remove fine foreign matter of a submicron size.

Embodiment 1~4

[0090] As catalyst metals, cobalt / molybdenum was dissolved in ethanol and coated on silicon wafers. Oxidation treatment is carried out at 250°C, so that the metal microparticles are uniformly formed on the silicon wafer. The ethanol was then heated to 700°C using an electric furnace to turn it into a vapor, forming multiwalled carbon nanotubes (MWCNTs) vertically oriented on the catalyst metal. In this way, cleaning members (1) to (4) having a layered member provided with a plurality of protrusions of a columnar structure as a carbon-based nanostructure on the surface were produced.

[0091] The multilayered carbon nanotube structures formed in the cleaning members (1) to (4) were observed with a scanning electron microscope (SEM). Table 1 shows the maximum diameter of the obtained multilayer carbon-based nanostructure and the length of the protruding part, and the density of the carbon-based nanostructure on the surface of the layered member. In addition, the dust removal p...

Abstract

A cleaning member that is free from staining at cleaning sites, being capable of simple and easy, unfailing, satisfactory removal of minute foreign matter, preferably foreign matter of submicron level; a delivery member with cleaning function including the cleaning member; and a method of cleaning a substrate processing apparatus with the use of the cleaning member or delivery member with cleaning function. There is provided a cleaning member comprising a layer member furnished on a major surface thereof with multiple protrusions of columnar structure, wherein the protrusions of columnar structure consist of a carbon nanostructure.

Description

technical field [0001] The present invention relates to a cleaning member for removing fine foreign substances, a conveying member with a cleaning function, and a cleaning method for a substrate processing apparatus using the cleaning member or the conveying member with a cleaning function. More specifically, the present invention relates to a cleaning member for removing fine foreign matter from a substrate or device from which fine foreign matter is to be avoided, such as semiconductors, flat panel displays, printed substrates, substrate processing equipment, etc., a conveying member with a cleaning function having the cleaning member, And a cleaning method of a substrate processing apparatus using the cleaning member or the conveying member with a cleaning function. Background technique [0002] In semiconductors, flat panel displays, printed circuit boards, and other manufacturing equipment and inspection equipment, various substrate processing equipment that avoids fore...
