Abstract
Ämnesord
Stäng
- Relaxation of SiGe layers grown selectively or non-selectively on oxide-patterned substrates using reduced pressure chemical vapor deposition was investigated. The influences of the buffer layer, the polycrystalline layer on the oxide and the opening size on the critical thickness for relaxation of SiGe layers have been studied in detail. High resolution reciprocal lattice mapping, atomic force microscopy and Normanski optical microscope have been used as the main characterization tools.
