摘要
PURPOSE: To provide a manufacture of a microcorner cube. ;CONSTITUTION: Exposure is performed to a layer of a photoresist 20 formed into a fixed thickness on the surface of a transparent board 10 by making use of a microscopic mask 30 in which transmittance or shading rate is reducing gradually by facing toward sides each from the center of a regular triangle and a triangular-pyramidlike microscopic protrusion 20' is formed by the photoresist through development. Since the form 20' of the photoresist is transferred to the transparent board 10 by engraving by performing anisotropic etching after that, the triangular-pyramidlike microscopic protrusion 10' which is comprised by combining three faces of equilateral right-angled triangles with each other in a state meeting at right angles is formed as a part of the transparent board 10.;COPYRIGHT: (C)1995,JPO
