    摘要: This invention describes a radiation-emitting semiconductor component based on GaN, whose semiconductor body is made up of a stack of different GaN semiconductor layers (1). The semiconductor body has a first principal surface (3) and a second principal surface (4), with the radiation produced being emitted through the first principal surface (3) and with a reflector (6) being produced on the second principal surface (4).The invention also describes a production method for a semiconductor component pursuant to the invention. An interlayer (9) is first applied to a substrate (8), and a plurality of GaN layers (1) that constitute the semiconductor body of the component are then applied to this. The substrate (8) and the interlayer (9) are then detached and a reflector (6) is produced on a principal surface of the semiconductor body.

    摘要: An LED chip comprising an electrically conductive and radioparent substrate, in which the epitaxial layer sequence (3) is provided on substantially the full area of its p-side (9) with a reflective, bondable p-contact layer (6). The substrate (2) is provided on its main surface (10) facing away from the epitaxial layer sequence (3) with a contact metallization (7) that covers only a portion of said main surface (10), and the decoupling of light from the chip (1) takes place via a bare region of the main surface (10) of the substrate (2) and via the chip sides (14). A further LED chip has epitaxial layers only. The p-type epitaxial layer (5) is provided on substantially the full area of the main surface (9) facing away from the n-conductive epitaxial layer (4) with a reflective, bondable p-contact layer (6), and the n-conductive epitaxial layer (4) is provided on its main surface facing away from the p-conductive epitaxial layer (5) with an n-contact layer (7) that covers only a portion of said main surface (8). The decoupling of light from the chip (1) takes place via the bare region of the main surface (8) of the n-conductive epitaxial layer (4) and via the chip sides (14).

    摘要: A method for fabricating a radiation-emitting semiconductor chip having a thin-film element based on III–V nitride semiconductor material includes the steps of depositing a layer sequence of a thin-film element on an epitaxy substrate. The thin-film element is joined to a carrier, and the epitaxy substrate is removed from the thin-film element. The epitaxy substrate has a substrate body made from PolySiC or PolyGaN or from SiC, GaN or sapphire, which is joined to a grown-on layer by a bonding layer, and on which the layer sequence of the thin-film element is deposited by epitaxy.
