Abstract

Abstract A microprobe is constituted by a single crystal having an apex portion surrounded by facets having specific place directions and having specific crystal faces. The microprobe is provided on a part of a main surface of a substrate or a part of a thin film formed on the main surface. In one embodiment the microprobe is provided with a source electrode, a gate electrode, a drain electrode and a thin resistance, so as to form an MOS transistor for amplifying the microprobe.
