This invention identifies important geometric parameters of an adhesive microfiber with mushroom-shaped tip for improving and optimizing adhesive ability. The magnitude of pull-off stress is dependent on a wedge angle γ and the ratio of the tip radius to the stalk radius β of the mushroom-shaped fiber. Pull-off stress is also found to depend on a dimensionless parameter x, the ratio of the fiber radius to a length-scale related to the dominance of adhesive stress. Finally, the shape of edge tip, where the surface and sides of the mushroom-shaped tip join, is a factor that impacts strength of adhesion. Optimizing ranges for these parameters are identified.

The present invention is a method for controlling flatness of a wafer including the steps of: providing a holding member having a holding surface including a plurality of segments, where each of the plurality of segments includes a dry adhesive fiber structure; making the holding surface of the holding member adhere to a wafer to make the holding member hold the wafer; obtaining information on flatness of the wafer by measuring flatness of the wafer to; and releasing adhesion of the dry adhesive fiber structures to the wafer in a part of the plurality of segments of the holding surface of the holding member based on the information on flatness. This can provide: a method for controlling flatness by which flatness of a wafer can be controlled sufficiently.

A structure (140) for adhering to a surface so as to support a desired weight includes a substrate (110) and a polymer layer (120). The polymer layer (120) is mounted on the substrate (110). A plurality of flaps (142) are drawn from the polymer layer (120). Each of the plurality of flaps (142) have dimensions and a density so that when the plurality of flaps (142) are placed against the surface (400) and when a coherent shear force is applied thereto, the plurality of flaps (142) will adhere to the surface (400) with a strength sufficient to support the desired weight. Each of the plurality of flaps (142) includes a first side (210) and an opposite second side (212). At least one of the first side or the second side is meniscus shaped.
