Method for producing a matrix of individual electronic components and matrix produced thereby

A method for producing a matrix of individual electronic components comprising a step of producing an active layer on a substrate base, particularly by epitaxy, and a step of individualizing said components by forming trenches, particularly by etching, in the active layer, said individualization step leading to reveal at least the substrate base, further comprising the steps of:

• depositing a layer of functional material on the active layer;
• depositing a resin photosensitive to a preset radiation on the layer of functional material in such a way as to fill said trenches and to form a thin film on the upper face of the electronic components;
• at least partially exposing the resin to said radiation while underexposing the portion of resin filling the trenches;
• developing the resin in such a way as to remove the properly exposed portion thereof;
• removing the functional material layer portion that shows through following the development step;
• and
• removing the portion of residual resin.
