and a modified portion comprising: at least one first curved portion protruding from the plate-shaped body in a first direction and longitudinally extending in a second direction; at least one second curved portion protruding from the plate-shaped body in the first direction and longitudinally extending in a third direction, wherein the second direction and the third direction are substantially perpendicular to one another. ### Claim 2 (depends on 1) The mask of claim 1, wherein: the at least one first curved portion is one of a plurality of first curved portions; the plurality of first curved portions are spaced apart from one another; and the openings are positioned between respective pairs of the plurality of first curved portions. ### Claim 3 (depends on 1) The mask of claim 1, wherein the at least one first curved portion is disposed in one or more limited areas of the plate-shaped body. ### Claim 4 (depends on 3) The mask of claim 3, wherein the one or more limited areas correspond to a central area of the plate-shaped body. ### Claim 5 (depends on 3) The mask of claim 3, wherein the one or more limited areas are disposed adjacent to one or more edges of the plate-shaped body. ### Claim 6 (depends on 1) The mask of claim 1, wherein the shape of an axial cross-section of the first curved portion is a semicircle, a semioval, or a polygon. ### Claim 7 (depends on 1) The mask of claim 1, wherein: the at least one second curved portion is one of a plurality of second curved portions; the plurality of second curved portions are spaced apart from one another; and the openings are disposed between respective pairs of the plurality of second curved portions. ### Claim 8 (depends on 1) The mask of claim 1, wherein the plurality of second curved portions are disposed in one or more limited areas of the plate-shaped body. ### Claim 9 (depends on 8) The mask of claim 8, wherein the one or more limited areas correspond to a central area of the plate-shaped body. ### Claim 10 (depends on 8) The mask of claim 8, wherein the one or more limited areas are disposed adjacent to one or more edges of the plate-shaped body. ### Claim 11 (depends on 1) The mask of claim 1, wherein the shape of an axial cross-section of at least some of the plurality of second curved portions is a semicircle, a semioval, or a polygon. ### Claim 12 (depends on 1) The mask of any one of claims 1, wherein the first direction extends upward or downward from the plate-shaped body. ### Claim 13 (depends on 1) The mask of claim 1, wherein the modified portion comprises at least one of chromium, copper, nickel, magnesium, iron, tin, titanium, aluminum, and stainless steel. ### Claim 14 (depends on 1) The mask of claim 1, wherein the modified portion is formed from a polymer. ### Claim 15 (depends on 1) The mask of claim 1, wherein the modified portion is formed from the same material as or a different material from the plate-shaped body. ### Claim 16 (depends on 1) The mask of any one of claims 1, wherein the modified portion is configured to stretch under tension of the plate-shaped body to: enable a thickness of the plate-shaped body to be substantially maintained; and enable at least one other dimension of the plate-shaped body to increase. ### Claim 17 A mask, comprising: a plate-shaped body comprising openings; and a modified portion comprising: protrusions protruding from a first surface of the plate-shaped body; and depressions in a second surface of the plate-shaped body, the protrusions overlapping the depressions, wherein the protrusions are disposed in a pattern, the pattern comprising at least one row and at least one column of alternating protrusions and openings. ### Claim 18 (depends on 17) The mask of claim 17, wherein the protrusions are disposed in one or more limited areas of the plate-shaped body. ### Claim 19 (depends on 18) The mask of claim 18, wherein the one or more limited areas correspond to a central area of the plate-shaped body. ### Claim 20 (depends on 18) The mask of claim 18, wherein the one or more limited areas are disposed adjacent to one or more edges of the plate-shaped body. ### Claim 21 (depends on 17) The mask of claim 17, wherein the shape of an axial cross-section of at least some of the protrusions is a hemisphere, a cone, a polygonal prism, or a polygonal pyramid. ### Claim 22 (depends on 17) The mask of claim 17, wherein the at least one row and the at least one column are formed diagonally across the plate-shaped body. ### Claim 23 A mask, comprising: a plate-shaped body comprising openings; and a modified portion comprising at least two curved portions protruding from the plate-shaped body, the at least two curved portions comprising: at least one curved portion protruding in a first direction; and at least one curved portion protruding in a second direction opposite the first direction, wherein the at least two curved portions longitudinally extend in a third direction.
