Abstract

PURPOSE:To obtain a flat photoresist film for formation of a metal bump as well as to form an anodic oxide film or an anodic sulfide film on the sidewall part of a mesa using a simple process by a method wherein, before the performance of mesa etching, a flat metal film to be used for a bump is formed in advance on the substrate having a P-N junction. CONSTITUTION:After a semiconductor crystal layer 23, having the conductive type opposite to that of a substrate or the crystal layer 22 on the substrate, has been formed on a compound semiconductor substrate 21 or on the semiconductor crystal layer 22 formed on the substrate 21, a metal film 24 to be used for a bump is formed on the substrate. Then, the photoresist film 25 of a prescribed pattern is formed on the metal film 24, and the substrate or the crystal layer 22 is mesaetched until a P-N junction part 26 is exposed using said photoresist film as a mask. Subsequently, a protective film 27 is formed on the part other than the above-mentioned P-N junction exposed part 26', and after an anodic oxide film or an anodic sulfide film 28 has been formed on the exposed P-N junction part 26 ' using the protective film 27 as a mask, the unnecessary protective film 27 formed on the metal film 24 is removed. The above-mentioned protective film 27 is formed by conducting ECR-plasma CVD method, for example.
