摘要： A method of depositing a high quality low defect single crystalline Group Ill-Nitride film. A patterned substrate having a plurality of features with inclined sidewalls separated by spaces is provided. A Group Ill-Nitride film is deposited by a hydride vapor phase epitaxy (HVPE) process over the patterned substrate. The HVPE deposition process forms a Group Ill-Nitride film having a first crystal orientation in the spaces between features and a second different crystal orientation on the inclined sidewalls. The first crystal orientation in the spaces subsequently overgrows the second crystal orientation on the sidewalls and in the process turns over and terminates treading dislocations formed in the first crystal orientation.

摘要： Methods are disclosed for growing high crystal quality group III-nitride epitaxial layers with advanced multiple buffer layer techniques. In an embodiment, a method includes forming group III-nitride buffer layers that contain aluminum on suitable substrate in a processing chamber of a hydride vapor phase epitaxy processing system. A hydrogen halide or halogen gas is flowing into the growth zone during deposition of buffer layers to suppress homogeneous particle formation. Some combinations of low temperature buffers that contain aluminum (e.g., AlN, AlGaN) and high temperature buffers that contain aluminum (e.g., AlN, AlGaN) may be used to improve crystal quality and morphology of subsequently grown group III-nitride epitaxial layers. The buffer may be deposited on the substrate, or on the surface of another buffer. The additional buffer layers may be added as interlayers in group III-nitride layers (e.g., GaN, AlGaN, AlN).

摘要： One embodiment of a quantum well structure comprises an active region including active layers that comprise quantum wells and barrier layers wherein some or all of the active layers are p type doped. P type doping some or all of the active layers improves the quantum efficiency of III-V compound semiconductor light emitting diodes by locating the position of the P-N junction in the active region of the device thereby enabling the dominant radiative recombination to occur within the active region. In one embodiment, the quantum well structure is fabricated in a cluster tool having a hydride vapor phase epitaxial (HVPE) deposition chamber with a eutectic source alloy. In one embodiment, the indium gallium nitride (InGaN) layer and the magnesium doped gallium nitride (Mg-GaN) or magnesium doped aluminum gallium nitride (Mg-AlGaN) layer are grown in separate chambers by a cluster tool to avoid indium and magnesium cross contamination. Doping of group III-nitrides by hydride vapor phase epitaxy using group III-metal eutectics is also described. In one embodiment, a source is provided for HVPE deposition of a p-type or an n-type group III-nitride epitaxial film, the source including a liquid phase mechanical (eutectic) mixture with a group III species. In one embodiment, a method is provided for performing HVPE deposition of a p-type or an n-type group III-nitride epitaxial film, the method including using a liquid phase mechanical (eutectic) mixture with a group III species.
