Abstract

A method for producing optoelectronic devices and a surface-mountable optoelectronic device are disclosed. In an embodiment the method includes applying semiconductor chips laterally adjacent one another on a carrier, wherein contact sides of the chips face the carrier, and wherein each semiconductor chip comprises contact elements for external electrical contacting which are arranged on the contact side of the semiconductor chip and applying an electrically conductive layer on at least sub-regions of the sides of the semiconductor chips not covered by the carrier, wherein the electrically conductive layer is formed contiguously, and wherein protective elements prevent direct contact of the contact elements with the electrically conductive layer. The method further includes electrophoretically depositing a converter layer on the electrically conductive layer and removing the electrically conductive layer from regions between the converter layer and the semiconductor chips.
