Abstract
A method of manufacturing an optoelectronic device, including: a) transferring, onto a surface of a control circuit, a diode stack including first and second semiconductor layers of opposite conductivity types, so that the second layer is electrically connected to metal pads of the control circuit; b) forming in the active stack trenches delimiting a plurality of diodes connected to separate metal pads of the control circuit; c) depositing an insulating layer on the lateral walls of the trenches; d) partially removing the insulating layer to expose the sides of the portions of the first layer delimited by the trenches; and e) forming a metallization coating the lateral walls and the bottom of the trenches and contacting the sides of the portions of the first layer delimited by the trenches.
