This paper reports the efforts to develop a direct strain measurement system for micro/nano scale thin film materials.
Introduction Thin film materials are the basis of microelectronics devices and MEMS fabrication processes.
This is because the governing mechanisms for mechanical behavior of thin films often differ from those of bulk materials.
While tensile test has proven to be a universal method for extracing mechanical properties of materials, it has become difficult to monitor the applied load and displacement in such small scales.
