Method for surface treatment |
摘要 |
A method for surface treatment includes: a first step in which a surface treatment apparatus 1 and a substrate 10 in a state where a front surface 102 of the substrate 10 faces the surface treatment apparatus 1 are conveyed to the inside of a decompression chamber to decompress a plurality of concave portions 32 (enclosed spaces); a second step in which the surface treatment apparatus 1 and the substrate 10 are brought out from the inside of the decompression chamber to environment under atmospheric pressure in a state where the substrate 10 is being attracted to the surface treatment apparatus 1 with the use of a difference between negative pressure inside the concave portions 32 and atmospheric pressure; and a third step in which the surface treatment is carried out to a back surface 101 of the substrate 10 with the substrate 10 being attracted by the surface treatment apparatus 1.
