    摘要: A semiconductor component having a light-emitting semiconductor layer or a light-emitting semiconductor element, two contact locations and a vertically or horizontally patterned carrier substrate, and a method for producing a semiconductor component are disclosed for the purpose of reducing or compensating for the thermal stresses in the component. The thermal stresses arise as a result of temperature changes during processing and during operation and on account of the different expansion coefficients of the semiconductor and carrier substrate. The carrier substrate is patterned in such a way that the thermal stresses are reduced or compensated for sufficiently to ensure that the component does not fail.

    摘要: A semiconductor laser device (5) comprising at least one semiconductor laser chip (7) is provided, wherein the semiconductor laser chip (7) contains an active layer that emits electromagnetic radiation. Further, at least one corner reflector (1) is formed in the semiconductor laser chip (7). The corner reflector (1) has a first and a second reflective surface (14, 15), wherein the first and the second reflective surface (14, 15) are arranged at an angle of less than 90 degrees with respect to one another. This results in an improved emission characteristic of the radiation emitted by the semiconductor laser device (5).
