Abstract
The invention concerns a method of manufacturing an assembly of electronic components on a front surface of a semiconductor substrate comprising a plurality of field areas, each field area comprising at least one field and each field comprising at least one electronic component, the method comprising a plurality of photolithography steps to form a stack of layers forming each electronic component, each photolithography step defining a mask level and comprising the application of a mask successively on each field in photolithography equipment, the positioning of said mask on each field being performed relative to a reference mask level, one of the masks being designated as identification mask. The manufacturing method is remarkable in that:
