Abstract:
A MEMS-nanoindenter chip performs nanoindentation on a specimen. The MEMS-nanoindenter chip has an intender probe joined with an indenter tip. The indenter tip indents into the specimen. A reference probe is joined with a reference tip, the reference tip touches the specimen. Sensing capabilities are provided to measure the position of the indenter probe relative to the reference probe. The MEMS-nanoindenter chip enables highly accurate measurements since the frame stiffness is not part of the measurement chain any more. Furthermore, thermal drift during the nanoindentation is considerably reduced.
Abstract:
A system for testing MEMS-structures includes a microforce sensor, two or more multi-axis micropositioning units, at least one electrical probe and a sample holder on which a MEMS-structure is mounted. At least one of the multi-axis micropositioning units is motorized and at least one additional micropositioning unit is equipped with at least one electrical probe to apply electrical signals or to measure electrical signals at one or multiple locations on the MEMS structure. The system with the aforementioned components allows a combined electrical and probe-based mechanical testing of MEMS-structures.
