Abstract:
A method of manufacturing an aggregate of semiconductor micro-needles, comprising the steps of:forming on a silicon substrate a dotted mask for covering a large number of dot regions each having a diameter sufficiently small to cause the quantum size effects of said semiconductor, wherein a photoresist film is formed on said silicon substrate and then a part of said photoresist film is mechanically removed by means of a probe needle of a cantilever of an atomic force microscope so that the dot regions remain, the remaining portions of the photoresist film constituting said dotted mask; andetching said silicon substrate by using said dotted mask so as to form a large number of semiconductor micro-needles each extending from the surface of said silicon substrate to a specified depth.
