A comprehensive stress analysis of a Si-SiO2ñbased multilayer membrane has been performed to ensure a high degree of mechanical reliability at a high operating temperature (e.g. up to 400(C). Moreover, optimisation of the layout dimensions of the SOI membrane, in particular the aspect ratio between the membrane length and membrane thickness, has been carried out to find the best trade-off between minimal device power consumption and acceptable mechanical stress. |  | View paper | | ISBN: | 0-9666135-7-0 |
