    Abstract: The invention relates to a process for fabricating a semiconductor including a layer (50) of element-13 nitride comprising active zones (52) for the fabrication of electronic components, and inactive zones (51), the active and inactive zones extending over a front side (53) of the element-13 nitride layer, the concentration of crystal defects in the active zones being lower than the concentration of defects in the inactive zones, the process comprising steps consisting in: using a mask to form, in a starting substrate (10): o first regions for growing the active zones and o second regions (11) for growing the inactive zones, the mask comprising a plurality of apertures each defining an active zone feature on the starting substrate; and growing (700) the element-13 nitride layer comprising the active and inactive zones on the first and second regions, the process being noteworthy in that it furthermore comprises the following steps: receiving a theoretical feature pitch, the theoretical feature pitch corresponding to a desired distance between two adjacent active-zone features on the front side of the element-13 nitride layer; and calculating at least one mask pitch different from the theoretical feature pitch in order to compensate for active-zone feature shifts, the active-zone feature shifts being due to the conditions of growth of the semiconductor, the mask pitch corresponding to a distance between two adjacent apertures in the protective mask.
