Abstract : This thesis is intended to deal with reliability of RF-MEMS devices (switches, in particular) from a designer point of view using different fabrication process approaches. This means that the focus will be on how to eliminate or alleviate at the design stage the effects of the most relevant failure mechanisms in each case rather than studying the underlying physics of failure. The detection of the different failure mechanisms are investigated using the RF performance of the device and the developed equivalent circuits. This novel approach allows the end-user to infer the evolution of the device performance versus time going one step further in the Design for Reliability in RF-MEMS. The division of the fabrication process has been done using the Technology Readiness Level of the process. It assesses the maturity of the technology prior to incorporating it into a system or subsystem. An analysis of the different R&D approaches will be presented by highlighting the differences between the different levels in the TRL classification. This thesis pretend to show how reliability can be improved regarding the approach of the fabrication process starting from a very flexible one (LAAS-CNRS as example of low-TRL) passing through a component approach (CEA-Leti as example of medium-TRL) and finishing with a standard co-integrated CMOS-MEMS process (IHP example of high TRL).
