    摘要: A method for fabricating a semiconductor layer comprising: a) growing a semiconductor layer on a foreign substrate; b) forming at least one opening on the semiconductor layer, wherein the opening exposes the interface between the semiconductor layer and the foreign substrate; and c) removing at least part of the semiconductor solid state material along the interface between the semiconductor layer and the foreign substrate. The removing step c) is preferably achieved by selective interfacial chemical etching. The semiconductor layer may be utilized as a substrate for fabrication of a wide variety of electronic and opto-electronic devices and integrated circuitry products.

    摘要: The present disclosure involves an apparatus. The apparatus includes a photonic die structure that includes a light-emitting diode (LED) die. The LED die is a vertical LED die in some embodiments. The LED die includes a substrate. A p-doped III-V compound layer and an n-doped III-V compound layer are each disposed over the substrate. A multiple quantum well (MQW) layer is disposed between the p-doped III-V compound layer and the n-doped III-V compound layer. The p-doped III-V compound layer includes a first region having a non-exponential doping concentration characteristic and a second region having an exponential doping concentration characteristic. In some embodiments, the second region is formed using a lower pressure than the first region.
