Germanium epitaxial growth
WebMar 26, 2024 · Abstract Germanium on silicon has the potential to enable growth of high quality group IV semiconductors for the field of silicon photonics by being used as virtual buffers. In addition Ge layers can be used in the fabrication of passive components such as waveguides and resonators. WebThe present invention relates generally to a method and means for growing strained or relaxed or graded silicon germanium (SiGe) layers on a semiconductor substrate using a selective epitaxial growth process. In particular, the present invention provides a method for epitaxially growing SiGe layers at temperatures lower than 600° C. by using …
