    Abstract: A method for growing a III-V semiconductor structure on a SinGe1-n substrate, wherein n is from 0 to 1 is provided. The method includes the steps of: (a) bringing a SinGe1-n substrate to a high temperature; (b) exposing the area to a group V precursor in a carrier gas for from 5 to 30 min, thereby forming a doped region at said area; (c) bringing the SinGe1-n substrate to a low temperature; (d) exposing the doped region to a group III precursor in a carrier gas and to a group V precursor in a carrier gas until a nucleation layer of III-V material of from 5 to 15 nm is formed on the nucleation layer; (e) bringing the SinGe1-n substrate to an intermediate temperature; and (f) exposing the nucleation layer to a group III precursor in a carrier gas and to a group V precursor in a carrier gas.

    Abstract: A device and method for manufacturing a Si-based high-mobility CMOS device is provided. The method includes the steps of: (i) providing a silicon substrate having a first insulation layer on top and a trench into the silicon; (ii) manufacturing a III-V semiconductor channel layer above the first insulation layer by depositing a first dummy layer of a sacrificial material, covering the first dummy layer with a first oxide layer, and replacing the first dummy layer with III-V semiconductor material by etching via holes in the first oxide layer followed by selective area growth; (iii) manufacturing a second insulation layer above the III-V semiconductor channel layer and uncovering the trench; (iv) manufacturing a germanium or silicon-germanium channel layer above the second insulation layer by depositing a second dummy layer of a sacrificial material, covering the second dummy layer with a second oxide layer, and replacing the second dummy layer with germanium or silicon-germanium by etching via holes in the second oxide layer followed by selective area growth.
