Abstract:
1. A method for manufacturing an opto-microelectronic device from a first semiconductor substrate, comprising the production of at least one electrode of a pixel after a transfer of the first semiconductor substrate onto a second substrate, the method comprising: a first phase carried out before the transfer and comprising: i) forming at least one pattern made of a sacrificial material in a layer formed in the first substrate surface, ii) a lateral delimitation of the at least one pattern in the layer of the first substrate surface by an edge of a boundary material differing from the sacrificial material, a second phase carried out after the transfer and comprising a substitution of the electrode for the pattern including a removal of the sacrificial material of the pattern by a selective etching so configured as to attack the sacrificial material of the pattern and to preserve the boundary material without using photolithography.
