What is claimed is: 1. A method for determining the two-dimensional coordinates of sequential cross-sectional slices of a fiber bundle which may be used to form a chip or a micro-array comprising: (a) producing a series of sequential cross-sectional slices of a bundle of adhered linearly-aligned fibers, wherein each sequential slice comprises multiple fiber units that are bound or immobilized to each other, and each bound or immobilized fiber unit is produced by the cross-sectional slicing of the individual fibers in the bundle, wherein said fiber bundle comprises fibers containing one or more immobilized biological substance(s) and at least two coordinate reference points, (b) determining the two-dimensional coordinates of each fiber unit within a fiber alignment slice S(h) using the coordinates of the fiber units formed by said two or more coordinate reference points; (c) determining the two-dimensional coordinates of each fiber unit corresponding to those in fiber alignment slice S(h) which are in an adjacent or sequential fiber alignment slice S(i) of said fiber bundle, based on the coordinate data obtained for fiber alignment slice S(h) in step (b) and based on the positions of the coordinate reference points in the adjacent or sequential fiber alignment slice; and (d) repeating steps (b) and (c) to determine the two-dimensional coordinates of fiber units in one or more successive or adjacent fiber alignment slices of said fiber bundle. 2. The method of claim 1, wherein, in step (b), the two-dimensional coordinates of each fiber unit in slice S(h) are first determined relative to an XY plane, and the resulting values are then translated into a coordinate system based on the coordinate reference points in said slice S(h), to form translated coordinates for each fiber in slice S(h). 3. The method of claim 1, wherein said fibers are selected from the group consisting of hollow fibers incorporating an immobilized biological substance, porous fibers incorporating an immobilized biological substance, and porous hollow fibers incorporating an immobilized biological substance, wherein the biological substance is directly immobilized on the fiber, in the fiber, or both on and in the fiber. 4. The method of claim 1, wherein said fibers are fibers retaining a gel which incorporates one or more immobilized biological substance(s), whereby the biological substance is immobilized on the fiber, in the fiber, or both on and in the fiber. 5. The method of claim 2, wherein, in step (c), the two-dimensional coordinates of each fiber unit in slice S(i) are first determined relative to an XY plane, using the corresponding translated coordinates for each fiber in slice S(h), and the resulting values are then translated into a coordinate system based on the coordinate reference points in said slice S(i). 6. The method of claim 3, wherein the one or more biological substance(s) is one selected from a group consisting of: (a) nucleic acid, amino acid, sugar or lipid; (b) a polymer consisting of one or more kinds of ingredients from the substances stated in (a) above; and (c) a substance interacting with substances stated in (a) or (b) above. 7. The method of claim 4, wherein said fibers are selected from the group consisting of solid fibers, hollow fibers, porous fibers and hollow porous fibers. 8. The method of claim 6, wherein the one or more biological substance(s) is nucleic acid. 9.
