Abstract
In this study we investigate the influence of the substrate preparation on the mechanical properties of indium phosphide layers used for hetero-micromachining. These layers were grown on silicon by metalorganic vapour-phase epitaxy. Exploiting the etching selectivity of indium phosphide versus silicon we realized freestanding cantilevers oriented in <100> and <110> crystal directions. Fracture-stress measurements revealed that cantilevers fabricated from a layer grown on structured substrates show a lower value compared to those grown on unstructured silicon.
