Abstract
The invention relates to a method for producing a matrix of electronic components, comprising a step of producing an active layer on a substrate, and a step of individualizing the components by forming trenches in the active layer at least until the substrate emerges. The method comprises steps of depositing a layer of functional material on the active layer, depositing a photosensitive resin on the layer of material in such a way as to fill said trenches and to form a thin film on the upper face of the components, at least partially exposing the resin to radiation while underexposing the portion of resin in 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 after the development step, and removing the remaining portion of resin.
