| Summary: | As the demand for MEMS devices operating in high temperature environment is increasing, it is important to ensure and improve the reliability of the devices. In this project, test structure with integrated metal thin film micro-heater and resistance temperature detector was used for high temperature micro-tensile test.
Instead of furnace which requires heating of other equipment components, localized resistive heating method by using integrated titanium/platinum (Ti/Pt) thin film micro-heater was proposed. This report describes the development of a novel high temperature micro-tensile test and design consideration of the test structure. Electro-thermal performance of the integrated micro-heater was first analysed, followed by the micro-tensile test of single crystal silicon (SCS) test specimen with (100) surface orientation and <110> tensile direction at elevated temperatures, up to 300 °C. Effect of temperature on the Young’s modulus was presented with the experimental results. |
