Patent ID: 6938653

Claim:
A method for filling a fluidized material into a hole having a bottom, the hole disposed on one surface of a sheet member, the method comprising the steps of: depressurizing a first closed space, which is formed on a first region disposed at a predetermined portion of the one surface of the sheet member, wherein the hole having the bottom is disposed on the one surface of the sheet member; depressurizing a second closed space, which is formed on a second region disposed at another predetermined portion of the one surface of the sheet member, wherein the second region is adjacent to the first region, wherein the second closed space accumulates the fluidized material, and wherein a degree of vacuum in the second closed space is lower than that in the first closed space; displacing the hole having the bottom together with the sheet member from the first closed space to the second closed space, wherein the hole having the bottom is depressurized in the first closed space in the step of depressurizing the first closed space; applying the fluidized material on the surface of the second region of the sheet member, the fluidized material accumulated in the second closed space; and filling the fluidized material into the hole having the bottom, the fluidized material applied on the surface of the sheet member, wherein the one surface of the sheet member, on which the hole having the bottom is disposed, is directed vertically downward, and wherein the first and second closed spaces are disposed vertically under the first and second regions, respectively.
