The strain imparted to 60 nm wide, silicon-on-insulator (SOI) channel regions by heteroepitaxially deposited, embedded silicon-carbon (e-SiC) features was measured using x-ray microbeam diffraction, representing one of the first direct measurements of the lattice parameter conducted in situ in an SOI device channel. Comparisons of closed-form, analytical modeling to the measured, depth-averaged strain distributions show close correspondence for the e-SiC features but 95% of the predicted strain in the SOI channel. Mechanical constraint due to the overlying gate and the contribution of SOI underneath the e-SiC in the diffracting volume to the measurements can explain this difference. © 2009 American Institute of Physics.
