  • Publication number: 20110101383
    Abstract: A semiconductor component comprising at least one optically active first region (112) for emitting electromagnetic radiation (130) in at least one emission direction and at least one optically active second region (122) for emitting electromagnetic radiation (130) in the at least one emission direction. The first region (112) is here arranged in a first layer (110) and the second region (122) in a second layer (120), the second layer (120) being arranged over the first layer (110) in the emission direction and comprising a first passage region (124) assigned to the first region (112), which first passage region is at least partially transmissive for the electromagnetic radiation (130) of the first region (112).

  • Publication number: 20100012955
    Abstract: A light-emitting diode arrangement comprising a plurality of semiconductor chips which are provided for emitting electromagnetic radiation from their front side (101) and which are fixed by their rear side (102)—opposite the front side—on a first main face (201) of a common carrier body (2), wherein the semiconductor chips consist of a respective substrateless semiconductor layer stack (1) and are fixed to the common carrier body without an auxiliary carrier, and to a method for producing such a light-emitting diode arrangement.
