    Abstract: The invention relates to a light-emitting diode chip (1), comprising a series of epitaxial layers (3) arranged on a substrate (2), which are equipped with an InGaN-based active structure (4) that emits radiation. A buffer layer (20) is provided between the substrate (2) and the active structure (4). The material or materials of the buffer layer (20) are selected in such a way that their epitaxial surface (6) is untensioned or slightly tensioned for the epitaxy of the active structure (4) at the epitaxial temperature(s). The active structure (4) has zones (5) rich in In that are arranged laterally adjacent to one another in relation to the epitaxial plane. The In content in said zones is greater than in the other zones of the active structure (4). The invention also relates to a preferred method for producing the chips.

    Abstract: The optoelectronic semiconductor chip has a growth substrate (1) with a structured growth surface, which has multiple projections (4) and hollows (3). An active series of deposits (5) are applied on the growth surface. The surface area of the active series of deposits is larger than the area of the lateral cross section (Q) of the growth substrate. The growth substrate consists of gallium nitride, silicon carbide, sapphire, indium gallium nitride, indium aluminum gallium nitride nad zinc oxide.

    Abstract: The method involves making a substrate with an epitaxial functional semiconductor layer sequence (2). The substrate (1) has a separation zone (4) provided by ion implantation, where the ion implantation follows epitaxial growth into the substrate (1) and takes place via the functional semiconductor layer sequence (2). A carrier substrate (6) is applied on the functional semiconductor layer sequence (2). The separation zone (4) is separated from the carrier substrate (6). The substrate (1) and the functional semiconductor layer sequence (2) have the same grating space.
