Abstract
PURPOSE: To obtain a fine pattern at high efficiency in operation without causing side-etching by making mesa-etching easy to progress, by forming conductive paths, which are provided onto a semiconductor substrate, apart mutually from the substrate surface to the upper part.
CONSTITUTION: On N+-type GaAs substrate 1, N--type layer 2 is grown, and on it, P--type layer 3 is formed to generate a PN junction. Next, electrode 4 of desired size is vapor-deposited or plated on layer 3 through a photoengraving process, and the remaining surface of layer 3 is covered with lst resist film 7. Then, metal thin film 8 is vapor-deposeted, the conductive-path formation region on it is covered with the 2nd resist film 9, and conductive path 5 is adhered onto film 8 by plating. Next, film 9, and films 8 and 7 are removed sequentially, and mesa etching is done reaching even substrate 1, so that the elements can be obtained which have conductive paths 5 away from the surface 1 of its substrate.
