Popis: This paper presents a new experimental setup dedicated to the evaluation of contact materials for MEMS switches. The setup is an alternative way to more complex equipment like modified SPM or nanoindenter (1-4). It has been designed to test various contact materials upon electrical cycling, without requiring any specific micro-fabricated test vehicles. The setup is compact and housed in a vacuum chamber, which can be filled with gas mixtures to evaluate contact materials under various environmental conditions. The experimental contact is made of a commercial reed blade, contacting on a tip with a curvature radius of a few microns. It mimics a sphere/plane experimental contact, at a scale similar to MEMS switch micro- contacts. The two contact parts are easily removable, and can be covered with the appropriate contact material. Preliminary tests focused on lifetime evaluation of gold contacts under nitrogen. To validate the relevance of this setup, contact degradation is compared to the degradation modes we studied previously in a magnetic MEMS switch (5, 6).
