A light-emitting diode chip (1), in which over a substrate (2), a series
of epitaxial layers (3) with a radiation-emitting active structure (4)
based on InGaN is disposed. Between the substrate (2) and the active
structure (4), a buffer layer (20) is provided. The material or materials
of the buffer layer (20) are selected such that their epitaxial surface
(6) for the epitaxy of the active structure (4) is unstressed or slightly
stressed at their epitaxial temperature. The active structure (4) has
In-rich zones (5), disposed laterally side by side relative to the
epitaxial plane, in which zones the In content is higher than in other
regions of the active structure (4). A preferred method for producing the
chip is disclosed.
