  • Publication number: 20200273757
    Abstract: Among other things, one or semiconductor arrangements, and techniques for forming such semiconductor arrangements are provided. For example, one or more silicon and silicon germanium stacks are utilized to form PMOS transistors comprising germanium nanostructure channels and NMOS transistors comprising silicon nanostructure channels. In an example, a first silicon and silicon germanium stack is oxidized to transform silicon to silicon oxide regions, which are removed to form germanium nanostructure channels for PMOS transistors. In another example, silicon and germanium layers within a second silicon and silicon germanium stack are removed to form silicon nanostructure channels for NMOS transistors. PMOS transistors having germanium nanostructure channels and NMOS transistors having silicon nanostructure channels are formed as part of a single fabrication process.
