    摘要: A method for production of a plurality of semiconductor chips (6) in a wafer composite. A semiconductor layer sequence (2) is grown on a growth substrate (1), metallization (3) is applied to the semiconductor layer sequence (2), a metal layer (4) is electrochemically deposited onto the metallization (3), and the semiconductor layer sequence (2) is then structured and separated to form individual semiconductor chips (6). The electrochemically applied metal layer (4) is particularly suitable for use as a heat spreader, for dissipation of the heat produced by the semiconductor chips (6).

    摘要: An optically pumped semiconductor laser device having a surface-emitting vertical emission region (1) and at least one monolithically integrated pump radiation source (2) for optically pumping the vertical emission region (1). The semiconductor laser device is distinguished by the fact that the pump radiation enters the vertical emission region (1) in the form of partial bundles of rays of radiation with different radiation directions so that the pump radiation and the fundamental mode of the vertical emission region (1) have an overlap which is suitable for the excitation of this fundamental mode. This device is based on the fact that the fundamental mode of the vertical emission region (1) is preferably excited when the spatial intensity distribution of the pump radiation matches the profile of the fundamental mode.
