Title: PROCESS FOR FABRICATING AN OPTOELECTRONIC DEVICE INCLUDING PHOTOLUMINESCENT PADS OF PHOTORESIST
Abstract:
The invention relates to a process for producing an optoelectronic device (1) including a matrix array of light-emitting diodes (4) and a plurality of photoluminescent pads (61, 62, 63...) that are each located facing at least some of said light-emitting diodes (4), including the following steps: - forming said plurality of photoluminescent pads (61, 62, 63...) by photolithography of at least one photoresist (51, 52, 53...) containing photoluminescent particles deposited beforehand on a carrier surface (3; 3'); and - forming reflective walls (101, 102, 103...) covering the lateral flanks (81, 82, 83...) of said photoluminescent pads (61, 62, 63...), by depositing at least one thin-layer portion (91, 92, 93...) on the lateral flanks (61, 62, 63...).
