[SPI.NANO]Engineering Sciences [physics]/Micro and nanotechnologies/Microelectronics - Abstract
International audience; This paper demonstrates the validity of a new methodology using a commercial nanoindenter coupled with electrical measurement on test vehicles specially designed to investigate the micro-scale contact physics. Dedicated validation tests and modelling are performed to assess the introduced methodology by analysing the response of gold contact with 5 µm² square bumps under various levels of current flowing through contact asperities. Contact temperature rising is measured leading to shifts of the mechanical properties of contact material and modifications of the contact topology. In addition, the data provide a better understanding of micro-contact behaviour related to the impact of current at low- to medium-power levels.

[SPI.NANO]Engineering Sciences [physics]/Micro and nanotechnologies/Microelectronics - Abstract
International audience; For the DC contact RF MEMS, it has been identified that most of the limitations are related to the quality and the repeatability of the contact that drive the RF performances and the reliability. In order to propose new generation of RF MEMS devices, it is important to get a deeper insight on the physic of contact in order to choose appropriate materials. As part of our study on the electrical contacts of RF MEMS micro switches, the need of multiphysics software offering a well developed solver to simulate many mechanical contact problems coupled with other physics, with a reduced time of calculation and good accuracy on the results is under investigation. As a first step, we need to validate the results of the numerical platforms existing in our laboratory. To do so, a static Hertz contact problem is simulated using ANSYS 10 and COMSOL 3.3 and we compared the results of the simulation with the analytical model. The second step consists of comparing the capabilities of each software to model interaction between objects and solve a variety of contact problems. Then we compare the facilities for the user to fit the contact parameters in the model in order to obtain an accurate solution of our problem. This study permits us to choose the software the most efficient for our application. The accuracy of ANSYS, the various methods available to solve the wide variety of contact problems and with a minimum effort from the user, makes of ANSYS's solver an excellent candidate to be used in our project. Especially, the real topography of the contact surfaces can be included in finite element simulations.

[SPI.NANO]Engineering Sciences [physics]/Micro and nanotechnologies/Microelectronics - Abstract
RF MEMS devices have already demonstrated very attractive performances to introduce some intelligence in the front end architectures. The insertion of RF MEMS into real architecture will necessitate reduced actuation voltage, dimensions and a better control of the electrical and electromechanical behavior that will give more importance to surface effects and their understanding and modeling. So far, surface effects were ignored in the analysis, because of the difficulty to generate a rough surface model and also to simplify the model in order to reduced computation times. With the increase of computation capabilities, the topography of the surface can be included in finite element simulations if appropriate simulation methodology is implemented. In order to give an explanation to the microcontact degradation phenomenon, gold DC contact switches are tested on an experimental set up in NOVAMEMS that allows the switch ageing under controlled atmosphere and makes possible the analysis of contact behavior with cycling. A correlation is established between the electromechanical characterizations and finite element simulations. From the surface characterization, we generate the real shape of both rough surfaces that come into contact and to predict the real contact area and size of each contact spots. The obtained results show actually an increase in contact resistance with cycling. However, the variation isn't as large as the experimental measurements. Other failure phenomena have to be taken into account such as organic deposits, contamination or hardening to complete the analysis.
