Abstract
An optoelectronic component and a method for producing an optoelectronic component are disclosed. In an embodiment a method includes providing at least one light-emitting semiconductor chip comprising a sapphire substrate and an epitaxially grown layer sequence, arranging the light-emitting semiconductor chip with a side facing away from the sapphire substrate on a carrier, detaching the sapphire substrate from the semiconductor chip, applying a converter element on a region of the semiconductor chip in which the sapphire substrate was detached, arranging the semiconductor chip on an auxiliary carrier so that the converter element faces the auxiliary carrier and detaching the carrier from the semiconductor chip.
