Abstract: A method for forming SiGe-based regions with different Ge concentrations is provided. After defining the regions 1, 2 on a SOI substrate, a grating of masking patterns is formed on at least one region 2. After the epitaxial growth of a Ge-based layer in each of the regions, a first vertical diffusion is carried out. A second horizontal diffusion is then carried out such that the Ge diffuses beneath the masking patterns of the region 2. Thus, the region 2 has a Ge concentration that is lower than the Ge concentration of the region 1.
