摘要： The non-polar or semi-polar Nitride film is grown using Metal Organic Vapor Phase Epitaxy over a substrate. The in-situ grown seed layer comprising Magnesium and Nitrogen is deposited prior to the Nitride film growth. The said seed layer enhances the crystal growth of the Nitride material and makes it suitable for electronics and optoelectronics applications. The use of non-polar and/or semi-polar epitaxial films of the Nitride materials allows avoiding the unwanted effects related to polarization fields and associated interface and surface charges, thus significantly improving the semiconductor device performance and efficiency. In addition, the said seed layer is also easily destroyable by physical or chemical stress, including the ability to dissolve in water or acid, which makes the substrate removal process available and easy. The substrate removal provides the possibility to achieve exceptional thermal conductivity and application flexibility, such as additional contact formation, electromagnetic radiation extraction, packaging or other purposes suggested or discovered by the skilled artisan.

摘要： The current invention introduces a method of crystal film's growth of Gallium Nitride and related alloys over a novel class of the substrates using Vapor Phase Epitaxy technique. This said novel class of the substrates comprises single crystal lattice matched, partially matched or mismatched metallic substrates. The use of such substrates provides exceptional thermal conductivity and application flexibility, since they can be easily removed or patterned by chemical etching for the purposes of additional contact formation, electromagnetic radiation extraction, packaging or other purposes suggested or discovered by the skilled artisan. In particular, if patterned, the remaining portions of the said substrates can be utilized as contacts to the semiconductor layers grown on them. In addition, the said metallic substrates are significantly more cost effective than most of the conventional substrates. The use of Vapor Phase Epitaxy allows growing the epitaxial layers with different and/or variable alloy composition, as well as heterostructures and superlattices.

摘要： A method of providing a metal contact to n-type Gallium Nitride is disclosed. The method does not require high temperatures that often lead to a degradation of semiconductor materials, dielectric films, interfaces and/or metal-semiconductor junctions. The method can be applied at practically any step of a semiconductor device fabrication process and results in high quality ohmic contact with low contact resistance and high current handling capability. Present invention significantly simplifies the fabrication process of semiconductor devices, such as Gallium Nitride-based Light Emitting Diodes and Laser Diodes, while improving the resulting performance of the said devices. The invention can also be applied to improve the performance of electronic devices based on Gallium Nitride material system, especially where an additional annealing step is beneficial during the fabrication process.
