    Abstract: The invention relates to two methods for producing a thin-film semiconductor chip based on a III/V-III/V connection semiconductor material, said thin-film semiconductor chip being suitable for generating electromagnetic radiation. According to the first method, an series of active layers (1), capable of generating electromagnetic radiation, is applied to a growth substrate (2), the front face (12) of said series facing the growth substrate (2) and the rear face (11) facing away from the growth substrate (2). At least one dielectric layer (3) is applied to the rear face (11) of the series of active layers (1) as part of a reflective series of layers (51) and energy is applied with the aid of a laser in restricted volumetric areas (8) of the dielectric layer (3) to create at least one opening (4) facing towards the rear face (11) of the active series of layers (1). At least one metallic layer (5) is then applied as an additional part of the reflective series of layers (51) so that the opening (4) is filled with metallic material and at least one rear electrically conductive contact point (6) is configured that faces towards the rear face (11) of the active series of layers (1). A support (8) is then applied to the reflective series of layers (51) and the growth substrate (2) is removed. According to the second method, a reflective series of layers (51) is applied to the active series of layers (1) and energy is then applied with the aid of a laser in a restricted volumetric area (6) of the reflective series of layers (51) to create at least one rear electrically conductive contact point (6) facing towards the rear face (11) of the active series of layers (1).
