摘要
PURPOSE: A micro-lens array manufacturing method and an optical sensor array manufacturing method using the same are provided to secure an enough active area of an optical sensor by applying a lens array, in which micro-lenses are repetitively and regularly arranged, to a sensor array.;CONSTITUTION: A method for manufacturing an optical sensor array adopting a micro-lens array is as follows. A plurality of optical sensors(310) are arranged on a sensor board(300). A lens array(340), in which micro-lenses are repetitively and regularly arranged corresponding to the optical sensors, is placed on a spacer arranged around the optical sensor array. The micro-lenses have a flat bottom surface and a top surface which has the same curvature even when viewed at any position of the bottom surface.;COPYRIGHT KIPO 2011
