AFM/STM probes are based on whiskers grown by the vapor-liquid-solid (VLS) mechanism. Silicon cantilevers oriented along the crystallographic plane (111) are prepared from silicon-on-insulator structures that contain a thin layer (111) on a (100) substrate with SiO2 interposed layer. At removal of solidified alloy globules inherent in the growth mechanism sharpening of the whiskers takes place and, in such a way, the probes are formed. Cross-sections of the wiskers grown by the mechanism on the cantilevers can be controllably changed during the growth process so that step-shaped whiskers optimal for fabrication of the probes can be prepared. Also, whiskers with expansions/contractions can be formed that are important for fabrication of probes suitable for investigations in coarse surfaces, complicated cavitites, grooves typical for semiconductor microelectronics, etc. |
