摘要: A semiconductor device fabrication method in which a growing process is followed by a capping process in which a phosphor containing material cap layer is deposited over a final GaAs based layer. The wafer, containing many such substrates, can be removed from the reaction chamber to continue processing at a later time without creating an oxide layer on the final GaAs based layer. In continuing processing, a decomposition process selectively decomposes the phosphor containing material cap layer, after which a regrowing process is performed to grow additional layers of the device structure. The capping, decomposition and regrowth processes can be repeated multiple times on the semiconductor devices on the wafer during device fabrication.

摘要: Embodiments of the present disclosures provide methods and apparatus for manufacturing semiconductor devices such as transistors used for amplifying or switching electronic signals. Specifically, embodiments of the present disclosure generally relate to a semiconductor device having a film stack including an interlayer of semiconductor material and a buffer layer of semiconductor material underneath an active device layer. In various embodiments, the interlayer may include group III-V semiconductor materials formed between a first surface of a silicon-based substrate and the buffer layer. In certain embodiments the buffer layer may comprise group IV semiconductor materials. The interlayer may have a lattice constant designed to mitigate lattice mismatch between the group IV buffer layer and the silicon-based substrate. The buffer layer may provide improved integration of the active device layer to improve the performance of the resulting device.

摘要: Techniques are provided that can impart sufficient electrical conductivity to a semiconductor crystal exhibiting low doping efficiency for silicon atoms, such as InGaAs, by implanting only a small amount of silicon atoms. Such a semiconductor wafer may include a first semiconductor crystal layer, a second semiconductor crystal layer exhibiting a conductivity type that is different from the first layer, a third semiconductor crystal layer exhibiting the conductivity type of the first layer and having a larger band gap than the second semiconductor crystal layer, and a fourth semiconductor crystal layer exhibiting the conductivity type of the first layer and having a smaller band gap than the third semiconductor crystal layer. The fourth semiconductor crystal layer contains a first element that generates a first carrier of a corresponding conductivity type and a second element that generates a second carrier of a corresponding conductivity type.
